I previously received help from Gringo over on this thread (http://www.bleepingcomputer.com/forums/topic413593.html
), but since removing (I think) the malware, I've run into a new problem: the computer has, each of the past few days, suddenly shut down. Gringo suggested that I post a new topic here in the Vista forum.
I looked at the Event Log and it mentions kernel power. I also see this error message in the log: "The speed of processor 0 is being limited by system firmware. The processor has been in this reduced performance state for 2 seconds since the last report."
The other very weird behavior that I can't find the source for is that one of the svchost.exe processes seems to take up 300,000 -- even when no programs are running. I can't figure out why the CPU is working so hard.
Please let me know what additional information I can provide, and I am happy to do so. Thank you!
