As shown in the screenshot above, Avira appears to be the best followed by G Data (dual antivirus engine) and then Kaspersky. Do note that being at the top of the chart means there are more false positive as well, meaning to say ‘some’ viruses caught by these antivirus might not be a virus, this will cause some problem for system admin as they run back and forth explaining and monitoring the situation whenever a false positive occurs.

p.s. I was using Norton Antivirus on computer 1 and AVG on computer 2, while transfer my entire backup files, both failed to detect a ‘keygen’ as Trojan. When I purchased my new Sony Vaio FW55GF, it comes installed with Avira Free, it caught the Trojan. Not sure if it a false positive.
