$500 fee and I don't work weekends. 😀
Seriously if you really have a Malware, am out. But if this is happening RIGHT NOW, I would first disconnect myself from the Internet, do a reboot, and note whether it's doing it again, and look for files that are being modified, say the last 30 minutes, the file name(s) and location(s) may give you a clue whether it's some run-away application you just installed.
p.s.: Oh there is another thread about the machine indexing, u may want to turn it off.
