Look at his system infections, I doubt it will even update. Avasts service is even showing its infected on the list from what i can read…
Maybe prepare yourself, I would get ahead on the ball and maybe download this program

Download Malware bytes
http://www.techspot.com/downloads/4716-malwarebytes-anti-malware.html

Run a scan and when the items present themselve try removing them with malware bytes, save a log and post it here when completed

After the log completes I highly suggest checking back here, this issue is out of my experience and looks severe, Essexboy has been notified, he’s the malware expert on the site, he will advise you on the steps to take after the malware bytes scan.
