The thing is, I have Windows 7 and don't have MV C++ 2010 and have Avast 6 installed and mine is working fine with 2008. I think 2008 is all that is required. How long did you have Avast installed before having problems?
can you go into programs and features and screenprint everything that has to do with Microsoft Visual C++? Just want to see what is there. I may be barking up the wrong tree on this. Not for sure.
