Hello, I have searched hundreds of threads here and have not seen this problem mentioned, which I take as a bad sign. A computer running Windows XP had a problem after choosing a user. The mouse pointer left a trail behind it, and the computer was very slow to respond. The mouse pointer looked fine before choosing a user though, for what it's worth. I ran ESET NOD32 EAV. The scan showed 1900 infectious items and counting when I left it for the night. In the morning, I expected to see the total count finished, but instead, the computer kept trying to reboot. It must have been trying all night. I see the manufacturers logo, and the XP logo. It hangs there and starts over again. I tried starting in "safe mode", and tried having it use the "last good configuration" option, but no changes. Any ideas? Any information that I forgot to give? Thanks!
