I have 2 frinds to send difrente jpg files, and the all fails when I use this settings in MSN to run Avast: C:\Program Files\Alwil Software\Avast4\ashQuick.exe

I do not think this is a ashquick.exe fault, it is saying the path is not found, could you try changing where msn saves the files that are uploaded to you please (i.e. desktop or my received files for example), i have a feeling this will solve the problem.
