Avast! Problem

Hello,

i have been using avast for like 4 months, it was fine. but today it started deleting alot of files in my C:\program files\ and also some files from my system folder >:( whats wrong with it??

Maybe you have virut ( file infector ). What are names and locations of the infections

avast! doesn’t delete files just by itself. Does it report any viruses? (if yes, what’s the name?)
