I haven’t even personally tested them all but I can still give you very good review on them. See what suits your needs best.
I used to use this along my other purchased anti-virus. It has ALMOST all main features you could possibly need. The bad side with free version happens to be few missing feature such as Root-kit scan, firewall and “web shield”. So it leaves some chances of infection. Still it is possibly the one of best free anti-viruses there is.
My friend has this. No significant problems, but I’m a bit sceptical. I don’t know why. It has although all features (even the ones AVG doesn’t have). If you want something simple, here you go.
Many people tell me that this is actually very good program and it has high detection rates, it also lacks some features such as firewall and web-guard.
