AVG Anti-Virus 7.5 Professional Edition intrigues consumers because of the popularity of the free version. However, reviews are very mixed. Every professional review rates AVG Anti-Virus Professional as average or worse. AVG earns mixed results in other lab tests as well. False positives are a weakness cited in one test. Many reviews say there's not enough difference between the free version and the paid version to merit the upgrade.

1. PC World
In conjunction with AV-Test.org, PC World tests eight antivirus applications under Microsoft Windows Vista. The reviews are comprehensive and detailed, except that compatibility with third-party anti-spyware and firewall programs isn't tested. Grisoft AVG 7.5 Anti-Virus Professional is ranked seventh of eight programs. Ineffectiveness and complexity of use don't offset the low cost.

This site ranks 17 antivirus programs, but testing details are sparse and most programs are rated excellent in most categories (only three of 60 ratings are below "very good"). AVG Anti-Virus Professional ranks eighth. Editors report that AVG Anti-Virus flunked a lab test conducted by West Coast Labs.

CNet does not test effectiveness in preventing malware; it relies on the independent lab tests, but Robert Vamosi evaluates other factors of usage. He thoroughly measures how each program affects computer speed. AVG Anti-Virus 7.5 Professional finishes last in the roundup of eight antivirus software programs.

A couple of dozen readers review AVG Anti-Virus Professional at CNet.com, but all customer reviews are favorable to the degree that the average rating is excellent. Several users are thrilled after switching from Norton and McAfee.

The university-based AV-Test.org does not review products; rather, it sells its performance-test results to other publications. PC Magazine commissioned a limited test that only determined each program's ability to detect malware (but not remove it). AVG is above average in this regard.
