I think free Avira is good, AVG is not good ... Kaspersky is good but the scan time is too long
I use free avira since 2008 & until this moment my computer is safe
Hopely my opinion useful
Thanks

AVIRA ANTIVIR FREE is the best.
I have been using Avast for quite a while and found it quite satisfactory
i run win 7 with avira on desktop pc
on my laptop i have xp+avira+zone alarm free firewall
i dont use zone alarm on win 7 because daemon tools dont work with it
AVG is good but he use a lot off resource specially the last version
AVAST is good to but he didn't detect some threat detected buy AVG and other ANTI virus
A month ago I'm trying Panda Cloud Antivirus Free and by the moment I'm very satisfied with it. The main feature is its low resources consumption.
nod32 is good.. i got no problems
If it would be for free, I would have to go with BitDefender. If I would have to go with a paid version, I would go with Symantec antivirus ( not Norton ) lately known as EndPoint Protection.
I use avast free with real time shield & web shield. It's very fast and low on resources for pc. So my tablet pc with 1gb ram & 1.1ghz processor is not slow.
