No computer system that goes online can be without an anti-virus application.  Luckily, there are anti-virus applications that you can download free. Here are two of the latest ones released.

Note that in a business environment Beanstalk Computing recommends a more professional antivirus solution.  This is for personal use only.

Published by AVG Technologies just this 11th of November, AVG Free 9 will work on Windows 2000, XP, Vista, and Windows 7. It has been optimized to use less memory and slow down your computer much less than previous versions, and is trusted by many users as they are already in their ninth version.

AVG 9 also has new features such as anti-phishing and  screening websites that you visit. Furthermore, it comes with a convenient safety ranking ratings for search engines which can save you a lot of time.

Looking at the new free anti-virus of Microsoft, Microsoft Security Essentials (MSE) Version 1.0, you might be even more impressed. It works best on Windows XP, Vista, and Windows 7.

Trying MSE, you will notice that it is has a simple, clear graphic interface that is very user-friendly. It comes with a green/red taskbar icon that quickly lets you know the status of antivirus quickly and easily.

For a free anti-virus software, MSE is surprisingly adept at what it does, and out chases AVG 9 as far as its friendly interface is concerned. Of course, AVG 9 has one solid wall to lean on: Its trust and history with users which can be hard to compete with.
