Avast should work just fine for you, and is better than AVG.
There were quite a few people that switched to Avast (myself included) when AVG 8 came out. AVG has had it's problems.

For the past few days AVG wouldn't update on my Vista Home Premium system. The icon was grey and when I tried to manually update, it said the program was already running (I kept it on all day long with no change and even had to use task manager to shut AVG down.) Today I installed Avast free version and uninstalled AVG. So far so good. I left the program way it came without setting anything up or modifying it. Hope this will take care of general av needs on the computer.
