    Just find CIS greatest in the list, I love its powerful firewall and the scan engine. However, it’s little bit larger than the previous version.

    This list is good but seems a little old. I’m actually following the top ten antivirus list here: http://www.toptenantivirus.net/ and planning to buy either of the two: norton antivirus or bitdefender antivirus. Both have very good user reviews of the net. I have used AVG in past but no longer like it because of its false positives.
