I found a couple of strange entries in Sysinternals Autoruns first in the Driver Autorun image path >> "usbohci__________File not found: C:\WINDOWS\System32\Drivers\usbohci.sys" Also this.... Boot execute, Autorun, Boot Execute, image path >> "NaBootMir_____File not found: NaBootMir" located at "HKLM\System\CurrentControlSet\Control\Session Manager\BootExecute" Looked there and yes was found via regedit.These entries were not there a few days ago. My system is XP pro SP3. If anyone has any ideas would be much appreciated. And yes did lots of searches but to no avail.
