Just installed XP and first scan I run in NOD32 finds an infection. Can't delete the file, NOD32 scan in safe mode crashes. Also can't delete the file in safe mode.

Here is my HJT log:

The problem is clearly the O20 - Winlogon Notify: byXNeEUm - C:\WINDOWS\SYSTEM32\byXNeEUm.dll, but I thought I'd check here to get rid of everything that looks suspicious.

Symptoms: slow connection to the internet occasionally. Windows Explorer error messages forcing me to restart explorer.exe.

Thanks!
