So now I'm back to AVG free and so far so good. Faster than either Avast or MS.

I don't believe that Microsoft's Security Essentials is slowing your PC.
I have Microsoft's Security Essentials running and also Avira .. and the PC is very fast. Es mentioned before, I had AVG running for some time. When I changed to AVG 9.0 I had some problems and removed it. I have Vista SP2, 64 bit.
