cheeriokilla: where did you read that "AVG Free is best free AV" ?
this is what Pc Pro says: AVG is perhaps the best established free antivirus package, with a service record more than a decade long. With longevity like that, it must be doing something right.
Indeed, in our malware tests it detected a credible 93% of threats - rubbing shoulders with commercial packages from Eset and Kaspersky."
what a joke....
a good antivirus / antimalware-program like fx. a2 detects over 99% !
a2 typically detects 99,8%....
