While PC Tools Internet Security and Spyware Doctor with Antivirus are truly 2 awesome anti-malware applications their free antivirus is not.
It’s now clear to me that the power of PC Tools comes from the fantastic detection and removal technology of Spyware Doctor. I downloaded the latest version of the Free antivirus from pctools.com and put it to task on my latest infected pc.
PC Tools Free Antivirus detected and removed over 40 viruses, but left everything else behind and was continuously corrupted (see screen shot below). In my test I had to re-install PC Tools Free Antivirus 2 times…on the 3rd time I halted the review.

If you’re looking for some good free antivirus then choose Avira AntiVir.
