I have the same problem. I actually ran avast twice after it found the malfunction and it found a virus (I think it did) so I ran it again while the computer rebooted, it found nothing. When it started again it instantly told me, once again, that I had the truminfi malfunction. I ran avast again. It once again told me I had a virus. So I´m thinking it only has the malfunction.
I´ll run the OTS recomended here, but like the post above I´m a novice so I really don´t know what to do next.
