Will there be conflict if avast and avg anti-virus run simultaneously?

Question

what other anti-virus is good for window vista OS?

Answer 1

Every anti virus would  conflict if you installed  another while one is existing.

Answer 2

Wow, it's so weird I stumbled across this question because I just deleted my AVG free and downloaded Avast tonight.

If you have AVG 8, I would highly suggest getting rid of it. You don't need the two programs when they both do the same thing. Plus, it'll bug out with other programs. Avast is much better than this new version of AVG, there have been tons of problems with it.

Just run Avast and check Windows Defender regularly. It will inform you if you need to update anything and they will run great together.
