alright im pretty computer illiterate. i have AVG antivirus, the free version, and my computer a while back started giving these error reports every time i try to open a program, program works after i click okay. "DLL C:\WINDOWS\system32\w8c6s4xcm66s.dll is not a valid Windows image." my computer has now started to pretty randomly restart for what i can see no reason. please help. i don't care if i have to wipe the hard drive. if the solution is free im okay with it.
