Why not? AVG is good enough for me 
Since I am using (over an year now) it I don’t have any problems with viruses and Troyan horses like I used to have before.
Besides this is avast forum, I’m an ex AVG user and I can’t compare them as avast is superior in my opinion: configurability, languages available, number of servers available to update (update reliability), flexibility, specific providers (like WebShield), etc.
AVG isn’t bad. It is just not better than avast 8)
