/>ClamWin is an open source program designed to work on Microsoft Windows operating systems.&nbsp; ClamWin will run on Windows 98/ME/2000/xp and 2003 versions.&nbsp; ClamWin is based on the open source ClamAV engine but with a graphical interface to make it much more user friendly.&nbsp; The only downside to using ClamWin is that it does not offer any real-time protection.&nbsp;In other words, it does not scan your system unless you ask it to.&nbsp; If you have less critical systems in your server room like a backup DNS or DHCP server then this could be a possible solution for you.&nbsp; As long as you schedule a scan manually as often as you feel it is needed, this could save you some bucks the next time your antivirus renewal comes up. <br
/>&nbsp; <br

Antivirus protection can be installed anywhere in the network, but is most efficient when implemented at both the perimeter firewall and the endpoints, such as desktop and laptop computers.</p><p><b>Security at the Firewall</b></p><p>Having antivirus protection at the perimeter firewall, rather than just on servers or endpoints using software-based solutions, is good for both saving costs and maintaining security. You can rely on perimeter antivirus on the firewall to protect your network and save money by keeping your bandwidth use down.</p><p><b>Integrated Security from Computer Protection Experts</b></p><p>A firewall performs many necessary security functions: intrusion detection, stateful packet inspection, network address translation, policy enforcement, and VPN tunneling. Though independent of antivirus protection, these jobs are consistent with the security you need from antivirus protection. Firewall manufacturers work with the best antivirus companies to bring you integrated, seamless security against viruses, worms, and other malware. This suite of protection-firewall and antivirus together-is referred to as Unified Threat Management.</p><p><b>Efficient Security Increases Network Performance</b></p><p>Perimeter antivirus stands as a central signature and heuristics engine that allows hourly updates, as well as streamlined installation and update management. It also gives<div

This takes the load off your servers by providing bandwidth-saving, centralized updating and variable scanning. All this is controlled by experts in security who understand how to balance risk against system performance. The hourly updates also provide an added security bonus-faster updates reduce the window of vulnerability to emerging threats.</p><p><b>What is the Best Way to Implement Antivirus Protection?</b></p><p>Antivirus software protects using two different basic methods: signature-based detection and heuristic detection.</p><p>Signature-based detection identifies viruses and other malware by comparing the contents of a file to a list of signatures. Good signature detection searches inside files to look at embedded files. This method can only be used on known threats, and requires frequent updates to remain viable.</p><p>Heuristic detection can be used to identify unknown viruses, sometimes called zero-day threats. File emulation is an approach that executes a suspected program in a virtual environment and logs what actions the program performs.</p><p>The only way to properly implement antivirus protection is to protect both the entry point to your network, the firewall, and your endpoints, such as servers, computers, and laptops with protection that defends you by deeply searching all inbound traffic via a firewall-based antivirus solution, and maintaining a complimentary (but not identical) solution locally. This is especially important when using laptops and other computers that travel outside your protected network.</p><p><b>How Infinitely Virtual, Juniper Networks, and Kaspersky Labs Protect Your Business</b></p><p>Infinitely Virtual chose Juniper Networks and its firewall-based antivirus solution from Kaspersky Labs to provide the best protection without sacrificing virtual server performance. Your virtual servers are protected from intrusion, viruses, and malware from the outside. This includes that carried over email and web traffic, the most common malware attack vectors, all without slowing down or crowding out the traffic you need to do business on your virtual servers.</p><p><p>Lisa Gecko is a staff writer for InfinitelyVirtual.com.<br

One cannot possibly comprehend the extent of damage that a single malicious code or a worm can do to a network of computers. Once the virus hits the primary nodes of the network like the server or the backup node, it is impossible to correct the damage caused. Though the situation can be brought under control and data recovered in most cases, it can result in a downtime of days to get the systems up and running.No related posts.]]></description> <content:encoded><![CDATA[<p><em>By: <b>David C Borderson</b></em><div

In a multitude of forms, it can remain hidden away in your system but far from dormant. Though a standalone PC is affected, the client-server network remains the worst affected since every single node in the network is targeted by the virus.

If malware was to find its way into the network, not only could confidential data be compromised, it may result in a situation where your local area network of PCs becomes inoperable for days or even longer. The loss of communication facilities can have a devastating effect on your turnover.</p><p>There are both free and subscription based server security packages currently available. Those designed specifically for servers will be different than what has been created to protect personal computers from threats. A server is a lot more complex and has a different set of security dynamics than a regular computer.</p><p>Before you install any antivirus software, you will need to be clear on your server&#8217;s exact specifications. The memory, operating system, hard drive size, and other features will need to be noted before choosing the right security application. Do not rush into making a purchase, take your time to compare as many different software as you can. As a general rule, free antivirus applications are not going to be comprehensive enough to offer complete protection. The only value of a free package would be as a trial before investing in a subscription.</p><p>The application you choose needs to automatically update its virus signatures on a daily basis. Usually, the problem of an infection occurs within seventy two hours of the code going live, it would be of no use if your firewall only identifies the problem a week after it has become widespread.

You would not want the software to protect your server, but at a cost of causing extremely slow network connections. For this reason, it can be worthwhile testing a number of applications to find out which uses up the least amount of resources.</p><p>How easy to use is the interface? This should be straightforward and simple to customize. Most antivirus security applications have a host of features, not all of which may be of value to you. For example, anti-spamming, internet scanning, and other tools may not be important. Being able to quickly alter the scan settings is essential.</p><p>You should not be overly concerned about the price of a business digital security suite. At the end of the day, the cost of downtime and lost data can be massive. For an investment of a couple of hundred bucks, you can have peace of mind that your hardware is as secure as theoretically possible.</p><p><p>David Borderson is a business Internet security consultant who helps businesses setup <a

If I remember well, April 2009 is the moment when Panda Security announced the first Cloud Antivirus software, in Beta stage at that time, a free security solution that benefits of another technology developed by Panda, the Collective Intelligence.

</script></div><p>It&#8217;s been a while since the cloud computing security services appeared for the first time as a magical security solution for computer users. If I remember, April 2009 is the moment when Panda Security announced the first Cloud Antivirus software, in Beta stage at that time, a free security solution that benefits of another technology developed by Panda, the Collective Intelligence. In a few words, it&#8217;s about a huge database built with results of analyzed samples received by Panda Security Labs during years, results that are accessible by all the users from the cloud automatically and almost instantly. To have an idea about the size of this database, consider that Panda analyzed hundreds of millions of samples until now, and the new samples are analyzed and classified in a few minutes.</p><p>In this way, in the moment when a new threat is identified, let&#8217;s say a possible new trojan or virus variant, named sometimes a zero-day malware, the signature and the disinfecting or removing instructions for that new trojan is automatically available for all the users of the cloud antivirus software, beating the common update technology of a classic antivirus.</p><p>Theoretically, this approach must lead to a lower computer resource(CPU and RAM memory) consumption, since the files analyzing job is passed to the Cloud servers. Maybe you will ask: What is the bandwidth consumed by this process of submitting files data to the servers, it must be huge? Well, it&#8217;s not the case, because the scanned files are not submitted to the servers in their int<div

When a connection attempt to a an IP or domain known to be used by the cloud antivirus will be detected, the HTTP requests for that IP will be blocked. Separately, the upload process of dubious files to the antivirus cloud servers is blocked.To accomplish this task, the trojan is looking for certain keywords in the HTTP requests, if a keyword is found then the subsequent communications with the sever are supressed. The cloud antivirus will be unable to access the &#8220;cloud knowledge&#8221; and as a consequence the end users are not protected anymore for the newest threats. This trojan could be the start of a nightmare for the cloud antivirus system developers and a big threat to the technology itself, because it highlights the weaknesses of this security system.</p><p>I agree that using these methods, a classic antivirus can also be blocked to update itself, but for a cloud antivirus the connection with the servers is of an utmost importance, it is the heart of its technology.</p><p>The Bohu trojan is presented to the supposed victim as a high-definition video player or video codec, of course fake, tricking the user to install it in the computer, so the social engineering is used as method of infection.</p><p>During the installation process several files with semi-random names and <em>.xml</em> extension, together with an executable file are dropped in <em>%Program Files%Baidu</em> folder and using these files, a new executable file is generated also with random name, which is the actual body of the <strong>Baidu trojan</strong>.</p><p>For example, Rising AV detect it as:</p><p><em>Dropper.Win32.Bobohu.a</em></p><p>Kaspersky AV as:</p><p><em>Trojan-Dropper.Win32.NSIS.tw</em></p><p>and Microsoft as:</p><p><em>Trojan:Win32/Bohu.A!Installer</em></p><p>to name only a few of its given names.</p><p>This newly created trojan will drop other malware files, which are actually its components:</p><ul><li>siglow.dll</li><li>siglow.sys</li><li>newnetgar.dll</li><li>spass.dll</li><li>dsetup.exe</li></ul><p>&#8230; and will add a registry entry with a random name &amp; value to run at computer start-up:</p><ul><li>HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRun<em>randomValue_here</em></li></ul><p>Until now, only 3 antivirus software vendors were affected: Kingsoft, Rising and Qihoo, all from China.</p><p>Meanwhile, they solved the problem providing signatures and solutions to neutralize this trojan, but the problem is conceptual and can be resumed in a few words: there is not a 100% reliable solution to protect a computer as far as it goes online, only an up-to-date antivirus, an up-to-date system and the common sense are the things which can protect us. Maybe the last one is the most important, because the common sense tells us to do not install any software in the computer, without knowing its origins and its reputation.</p><p><p>John Barrett, Editor at <a

</script></div><p>In the past, I&#8217;ve written about some of the things you can do to stave off the most common home-user issue: virus infection. Well, if so many home-users are infected so often, what do businesses -some with hundreds of computers &#8211; do to stay virus-free?</p><p>There&#8217;s a big difference between the typical business computer and the typical home computer: the network it sits on. Because most business PCs are part of a large, server-based network, there are some things that we can do to protect them. Note: &#8220;server-based&#8221; means that a powerful computer/server is responsible for &#8220;serving&#8221; the needs of the network.</p><p>1) Desktop Antivirus. We install antivirus software on every computer on the network. We use the same packages available to home-users. However, being part of a larger network, we can use the server to monitor the individual computers for antivirus compliance. Meaning: Using one server, we can make sure every computer on the network is up-to-date with its antivirus software &#8211; we don&#8217;t need to rely on each user to install/check their software themselves.</p><p>2) Email Scanning. Since many businesses use a central server to store their email, we can strip off viruses at that email server before the recipient gets it. So, if we keep that one email server updated with proper antivirus software, we can effectively strip off any virus coming over email (that, alone, solves 95% of the antivirus problem!).</p><p>3) Gateway Scanning. Many home users use a router to share the internet connection with se<div

Names like Linksys, Netgear and Belkin are very common. Business uses similar routers, but they have 2 big differences: They cost a lot more and they allow us to block certain types of content. So, we can install software on the router to block viruses from getting past the internet connection. It&#8217;s the equivalent of Comcast blocking the virus before it gets to your home network!</p><p>To sum it up: In a business setting, we can force computers to keep their antivirus software current, we can strip viruses out of email before they reach the recipient, and we can block viruses from entering the internet connection in the first place.</p><p><p>Have an IT question you&#8217;d like answered?

</script></div><p>It is quite possible you are inundated on a daily basis with spam mail and unwanted pop-ups which advertise the latest in spy-ware and antivirus protection. As un-amusing and counterintuitive as it may be, competition and the effective differences between competing antivirus application developers is so tight, that even the manufactures of antivirus programs are willing to exploit your computers weaknesses to advertise their solutions.</p><p>The sheer size and efficiency of the internet as well its billion-plus users makes new computer viruses more dangerous and virulent than ever. Viruses can literally spread around the globe in only minutes, effecting thousands of unprotected and unprepared users and businesses virtually instantly and simultaneously. The need for antivirus protection is of paramount concern for virtually all PC users.</p><p><strong>First Things First: What IS a Computer Virus?</strong></p><p>To be considered a true computer Virus, a program needs the ability to replicate itself and trigger its activity at specified events. A computer virus is just one of three types of programs known as &#8220;maliceware&#8221;. &#8220;Maliceware&#8221; are applications designed to damage, delete or steal your information, hijack your computer and even damage or destroy your computers hardware. The three types of &#8220;maliceware&#8221; you need to concern yourself with are Viruses, Trojans and Worms. Most antivirus programs are designed to detect and defend your PC from all three threats.</p><p><strong>What Does an Antivirus Program Do?</strong></p><p><div
class="new_content"><a
href="http://dgtgjmvkdtza0.cloudfront.net/wp-content/uploads/cc/Antivirus_On_Servers57.jpg"><img
src="http://dgtgjmvkdtza0.cloudfront.net/wp-content/uploads/cc/Antivirus_On_Servers57.jpg" alt='Antivirus On Servers' /></a></div>Antivirus programs take two common approaches to recognize threats to your computer.</p><p>1. Signature Detection: Via Signature Detection an antivirus application scans your computer, drives and storage devices for files that contain a code it recognizes as a virus variant.</p><p>2. Activity: An antivirus application will monitor the activity on your computer for suspicious behaviors i.e. modification of system files or folders and unauthorized connections to the internet to name two.</p><p>Signature detection generally requires the manufacturer of an antivirus application to obtain a copy of a specific virus and then reverse-engineer it to obtain markers relevant to its programming. These markers are then loaded into your antivirus software via updates. Signature detection is a sound methodology for detecting and protecting against computer viruses, however it can be rendered useless when faced with a virus for which is has no definition.</p><p>Antivirus applications that scan for potential computer virus activity can be more useful at detecting the latest threats than those reliant on signature detection. It is important to note that because many applications perform the same activities as a virus &#8211; writing and changing system files for example &#8211; a user can quickly become inundated with numerous and unnecessary warnings by antivirus applications that utilize this method for detection.</p><p>Most of today&#8217;s &#8220;solid&#8221; antivirus programs utilize a combination of both signature detection and virus activity to protect your computer against threats.</p><p><strong>How to Choose the Antivirus Program that is Right for You.</strong></p><p>If you try surfing the web for insight into what is the best antivirus program or manufacturer, you will quickly find yourself neck deep in a sea of advertisements which profess themselves to be legitimate and impartial evaluators of the available programs. The truth is, of the major manufacturers, no one solution can provide for all of your potential needs. They all have instances where they are not as effective as the competition at detecting or eliminating a specific infection or threat. There are many good Antivirus applications and manufacturers all vying for your business, be it for personal or business use, and choosing the correct application or manufacturer for your computer security can generally come down to a few simple questions.</p><p><strong>How at Risk are You?</strong></p><p>Asking yourself this question is perhaps the first and most important step toward choosing what degree of protection you need, and how much money you are willing to spend, on Antivirus protection. Risk generally equates to your computers exposure to outside applications, files or connections. If you were to operate a computer that would never come into contact with any program or file not manufactured by a secure source, then you have virtually no need for an Antivirus application. Simply put, if you never plan to connect your computer to the internet, download files with it or upload &#8220;at risk&#8221; files from outside data sources, you should have no need for Antivirus software.</p><p>If you are a casual user who perhaps connects to the internet on occasion through a temporary or dial up connection and only download or upload files and programs from reasonably secure sources, your need for an antivirus program is clear, however, your risk may be minimal. In this situation the types and range of protective applications can be kept to a minimum; a basic antivirus program designed to regularly scan your hard drive for infections should offer you the protection that you need. There are many good antivirus programs that will fit this need available as shareware &#8211; a free download &#8211; throughout the internet.</p><p>Now, if you are like what I would consider to be the majority of today&#8217;s computer users, you are a high risk user and need a wide variety of the most up to date antivirus programs available. If you have a broadband internet connection which keeps your computer connected to the internet 24/7. If you regularly upload and download files and applications from random and un-trusted sources, you need to invest in very thorough security for your computer. High risk users should invest in an antivirus program that offers real time scanning of all incoming and outgoing connections or files, a firewall to prevent unauthorized access to your PC via an open broadband connection, a pop-up blocker that prevents your computers web browser from being hijacked and adware scanners that detect pop-up, spy-ware, tracking and redirection software.</p><p><strong>Are you Purchasing for Business or Home?</strong></p><p>Antivirus software manufactured for business and home can be two very different applications both in cost and effectiveness. Home versions generally cost less and come with fewer options than business based antivirus programs. Generally the home user does not need the added functionality built into business versions and as such, I would not recommend that a home user invest in an antivirus solution designed for business.</p><p>Good antivirus software designed for business is focused on security, both from external and internal threats, as well as ease of maintenance. Most corporate versions of antivirus applications allow for a central point of control over entire networks. Protection can be divided between internet or application servers and individual PCs. New software updates are generally &#8220;pushed&#8221; from a central application server through the entire network, allowing for simplicity and assure-ity of a network&#8217;s protection. Most times, corporate versions of antivirus applications do not allow individual users within a network to make changes to their protection settings; this is of key importance when considering overall network security and stability.</p><p>As a business purchasing a corporate class antivirus suite, it is important that your protection extends to each individual user that will access your network. Exchange/mail and internet server protection is a must, as well as protection for mission-critical file and application servers. It is a good rule of thumb for IT managers within corporate environments to assume that all their users will do everything within their power to infect corporate equipment with viruses and threats. Though this most certainly is not true, assuming that users know how to protect themselves or their corporate computer environment from infection is in most cases professional suicide for the IT manger in charge.</p><p>Antivirus software for business is generally loaded with more options than software built for home, and as such is often times much more expensive on a whole. Usually business antivirus programs come as a server based application. Clients, or additional licenses, are purchased for each computer or user that connects to the antivirus server.</p><p><strong>With Regard to the Antivirus Program Itself:</strong></p><p>Determining the true quality and effectiveness of an antivirus program can sometimes come down to how often the manufacturer releases updates to the program. New viruses are introduced to the web on most certainly a daily, if not hourly basis. The best antivirus manufacturers release updates on a daily basis and often offer updates to their programs on a real-time, as needed basis. The ability for an antivirus software manufacturer to release constant, and relevant, updates to their programs should be of great concern to the user. Not having the latest updates can almost be as dangerous as having no protection at all.</p><p><strong>Other Important Factors to Consider:</strong></p><p>1. The programs compatibility with your current set up and operating system? &#8211; If you are still using Windows 98 and you are purchasing an antivirus software manufactured in 2006, chances are it is not compatible with your computer.</p><p>2. How much in the way of system resources does the program use? &#8211; Just like all applications and operating systems, antivirus applications will use your computers processing power, memory and storage space to function. Keeping this use to a minimum will help to keep your computer operating at peak performance.</p><p>3. What kind of protection does the software offer? &#8211; Does the program offer protection against multiple threats such as Worms and Trojans? Will the program scan incoming and outgoing text messages and e-mails?</p><p>4. Cost &#8211; How much will the protection cost you over the life of your usage? &#8211; Most antivirus programs require that you subscribe to their service and then purchase updates on a yearly basis. The costs of these updates can vary widely between manufacturers and should be considered when making your final decision.</p><p>Answering these questions truthfully though an honest assessment of your PC usage will help to guarantee that you invest the proper amount of money and time into ensuring your PC and data are safe and secure.</p><p><p>Copyright 2006 <a

</script></div><p>Whether you&#8217;re preparing to pass the Network+ or Cisco CCNA certification exam or not, you must not underestimate the importance of antivirus programs and virus definition updates.  With all the attention we pay to viruses and their prevention, I feel a little silly even saying that.  But&#8230;.</p><p>If there&#8217;s one thing you must have working at full capacity in your network, it&#8217;s the antivirus programs.</p><p>If there&#8217;s one thing that is commonly overlooked when it comes to updates, it&#8217;s the antivirus programs.</p><p>In today&#8217;s world, your network must be protected from both internal and external antivirus threats.  By implementing and executing an aggressive antivirus strategy, you can greatly reduce your network&#8217;s chances of being hit with a virus.  Literally hundreds of millions of dollars in productivity are lost every year due to virus attacks, along with a few jobs.  Make sure both your network and career are protected!</p><p>You may be asking yourself what this has to do with the CompTIA Network+ certification exam.  To earn this important computer certification, you&#8217;ve got to display knowledge of threats to your network and how to stop them &#8211; and viruses are at the top of that list.</p><p>Before we discuss how to stop viruses, let&#8217;s discuss exactly what a virus is.  All of the following are bad, but they&#8217;re not all viruses.</p><p>Just as a human virus is spread through contact, so is a computer virus.  A virus is a program that gets onto a computer without a user&#8217;s knowle<div
class="new_content"><a
href="http://dgtgjmvkdtza0.cloudfront.net/wp-content/uploads/cc/Antivirus_On_Servers56.jpg"><img
src="http://dgtgjmvkdtza0.cloudfront.net/wp-content/uploads/cc/Antivirus_On_Servers56.jpg" alt='Antivirus On Servers' /></a></div>dge and then performs an action that can range from mischievous to destructive.  For a virus to be spread, there has to be some kind of contact between an infected user and another user &#8211; generally, that contact is the forwarding of an email that has an attachment that contains a virus.</p><p>A worm is a type of virus, but a worm can spread on its own without any &#8220;help&#8221; from the infected host.  Even worse, a worm can replicate on its own, resulting in many more worms attacking other hosts.  A common worm attack involves the worm sending a copy of itself to every single user listed in the infected host&#8217;s email address book.</p><p>A third, more insidious attacker is the Trojan Horse.  In history, the Trojan Horse was presented as a gift to Troy by the Greeks, and it was filled with Greek soldiers who attacked once the Horse was taken inside the city&#8217;s defenses.  Today&#8217;s Trojan Horses attack in much the same fashion.  The program installed by the user may look legitimate and innocent, but there&#8217;s another program inside just waiting to attack the user&#8217;s computer.</p><p>It&#8217;s a good idea to periodically remind your end users about some basic steps they can take to help prevent unleashing a virus:</p><p>Don&#8217;t open email attachments from anyone outside the company.</p><p>Don&#8217;t download software and install it, especially what I call &#8220;fun and free&#8221; software such as gaming programs, animated cursors, etc.  Most of that software is safe, but a minority of those programs contain adware and could unleash a virus on your network.</p><p>Don&#8217;t open email from anyone you don&#8217;t know, especially if the subject line doesn&#8217;t make any sense. Just trash it.</p><p>End user education is important, but we have to face facts &#8211; it&#8217;s not perfect. That&#8217;s true for virus protection as well as network security.   I personally wish I had a dime for every password I&#8217;ve seen written on a sticky note that was attached to the monitor!  As network admins and engineers, we&#8217;ve got to be aggressive in the fight against viruses and not depend on others.</p><p>While we should certainly have an antivirus program on every server in our network, there is one point of communication that we&#8217;ve got to be particularly sensitive to, since this is where most viruses and worms make their way into our network &#8211; the email server.</p><p>We&#8217;ve got to be particularly vigilant about the email server&#8217;s antivirus protection, since this is where users come in contact the email attachments that can lead to so much trouble.  When a host is receiving email from an email server, the antivirus program on the client should scan that email even before it&#8217;s opened.</p><p>Attachments are a major source of viruses, and many networks now have a firewall strip attachments off before they even get to the email server.  Firewalls are devices used to filter traffic, and a firewall can be set to remove incoming attachments.  If attachments aren&#8217;t allowed to enter the network, end users can&#8217;t launch them and their potential viral payload.</p><p>This common configuration also gives you the option to reject incoming email that has an attachment, along with the option of notifying the sender that the email was filtered for that reason.</p><p>Bottom line:  every email attachment is a virus threat.</p><p>So how do you best protect your network against viruses, Trojan horses, and the like?

You should take the different precautions necessary to combat each threat. One safety measure that people take these days is to use a proxy server. Proxy servers are available all over the Internet and they have been right from its birth back in the mid 1990s.</p><p>A proxy allows you to remain anonymous online so that websites that you visit cannot see any of your details like your IP address, MAC address, browser type, geographical location etc. Usually when you want to visit a website, a request will be passed via your ISP across a network of computers so that you can receive the data. If you use a proxy, however, things change. The request goes via your ISP and then via the proxy. This effectively keeps you invisible from the sites you are visiting as the proxy website is acting as a middle man. The websites that you visit can no longer see your details. They can only see the details of the proxy. This is a fantastic advantage for privacy.</p><p>It is very easy to find a proxy website. Finding a reliable one, that you can trust however, is a different matter. If you use some common sense and do some research you will be able to find a decent one quite quickly. You should check websites forums, newsgroups, yahoo answers etc and find out what other people say about proxies and what they would recommend. This should help you determine if a proxy is reliable or not. Usually, if the proxy has b<div

Always make sure that your firewall is set to enabled and that you have a good antivirus package installed. Please remember to get regular updates on the antivirus package because there are new threats and viruses that evolve all the time. Ideally, the updates should be completely automatic too. This will save you lots of time.</p><p>If you want added protection then you should consider investing in a product that offers encryption. This will keep all data transmitted between you and its server encrypted and no one will be able to make sense of what is being sent and received. Even your ISP, who keeps logs of your Internet activities, will not be able to make sense of it. Please be aware that there is no reason why your ISP or someone could not decrypt it. This is possible so make sure that the product you are using or intent to use is reliable, trustworthy and that it does its job properly. Using all of these things in conjunction with one another should give you bullet proof protection and ensue you maximum privacy against snoops, viruses and all of the other threats that exist on the Internet today.</p><p>The author lives in the UK and has his own portfolio of websites online. One of them provides some reviews on some good products that help keep you more private and secure. You can go and take a look at them by visiting the web based proxy for some more information.
