My Avast! scan logs keep saying I have a rootkit called "MBR:\\.\PHYSICALDRIVE0" which I've tried to send to chest several times to no avail. It doesn't show up on the boot scans and I've had blue screen twice so far; once last night when I first got the rootkit and again today when I turned on my networking. When I managed to get it into safe mode, my laptop restarted itself before I could do anything.
Any help on fixing this will be much appreciated.
