AVG Antivirus Review

I'm using AVG free for years now, i've never had a problem accept the mistake they made with the windows dll wich caused my computer to fail booting .. It doesn't slow my computer down (i've heard otherwise but that is maybe because some people still use old computers) It is very easy to use, and its free.. so honestly i think it's the best you can get for ZERO money .. I have tried avast in the past but to my opinion it wasn't up to point yet. Now i hear avast might my as good as AVG and that might be absolutly so but i'm happy with AVG. i'm glad it didn't destroy important data years ago i understand if a lot of users switched to another program but in my opinion everybody can make a mestake, computers and programs are only as smart as what humans put into it :) If somebody disagrees i would like them to prove it to me.
