I have a problem in that my computer periodically freezes. Last time it happened, I did CTRL+ALT+DELETE to see what programs were running in the background. One came up that I did not recognize - sychost.exe. After doing some research on this, I found out it was a virus. However my OneCare does not detect/remove it. Also, doing a search of the C and D drives reveals nothing. How do I remove this virus? Why doesn't OneCare take care of this?
