protection and top-notch scan speed, but some nontechies might find its interface frustrating.
2. Alwil Avast Antivirus Home Edition Free Antivirus Software Avast Antivirus Home Edition provides solid antimalware protection and a good set of features, but its outdated interface needs a makeover.

3. Comodo Internet Security Free Antivirus Software Comodo Internet Security is not a good antivirus choice, owing to its lackluster malware detection and its tendency to produce false positives.
4. PC Tools Antivirus Free Edition Software PC Tools Antivirus, which neglects to detect spyware, allows far too many pieces of malware through for it to realistically protect any PC.

5. PC Tools Threatfire 4.5 Free Antivirus Software PC Tools' free behavior-based antivirus utility serves as a great supplement to your existing security software.

6. Panda Cloud Antivirus (Beta) Free Software Panda Cloud Antivirus provides great protection in an easy-to-use application, but it's still too deep in development to recommend.

7. Microsoft Security Essentials (Beta) Free Antivirus Software An effective but somewhat slow utility, Microsoft Security Essentials will be a solid contender when it comes out of beta around the end of 2009.

8. AVG 8.5 Free Antivirus Software Though AVG 8.5 Free has a good, straightforward interface and useful blocking of Web-based attacks, its malware blocking is below average.

9. Clamwin Free Antivirus Software This open-source antivirus software fails to get the job done, with disappointing malware detection and no real-time scanning.
