Hi,

the solution for this problem is to remove a hidden PNP driver.
Open XP Device Manager.
Select "Show Hidden Devices" from Menue.
Open PNP Tree and look for a driver named lime "swuurqlm.sys".
Disable or delete this driver and Reboot.
Voila.

Regards
Martin

Martin,

>> Open PNP Tree and look for a driver named lime "swuurqlm.sys".


You meant Non-Plug and Play Drivers, right ?

This system should *not* be Trusted. If a hidden driver was found on the
system then the likelihood that there may be other other hidden drivers,
basically a Rootkit or a rootkit-like component, present, too.
There's really no way to be 100% certain that all RKs have been removed.
Either *never* enter any personal information on this system, never do
any online banking, or better yet, *flatten it and reinstall the OS.*

Was it infected with the latest 'Antivirus 200x' malware ?
