My friend borrowed my USB to transfer files from her email to another computer for a presentation. The computer used to retrieve the files from her email was a school computer, probably loaded with viruses... But... as a friend, I couldn't say no. So she gave me back the USB after the presentation and I forgot to format it before inserting it back into my computer. Guess what? Avast scared the crap out of me when I heard "Warning you have a virus." So now, I'm stuck with a laggy computer, whose CPU is almost as stressed as I am. By the way, I've attached a ComboFix log as well as a Hijackthis Log. I'd love it if you have any tips or solutions leading to the cleaning of this computer!
