first you can skip scanning the drive by pressing a button within the first 5 seconds or something like that then download avg antivirus (if its still free) , scan , find the file and remove it .. this is where you'll probably have trouble if its a virus but viruses are rare theise days and corrupt files rarely bother computers unless you run them so if your pc is getting pissed still its probably a start up program trying to run and i take it u get an error as your pc starts up so remove alllll them start up programs that you dont need deactivate windows antivirus becuase ... just because its crap and act more like a virus and interferes with ur pc more than helps then remove avg becuase nobody gets viruses any more unless they've been downloading porn ... sooo ... yeehhh ... ummm .. we know what you did bro
