How to remove .sys file?
We really need more information to be able to help you. Your antivirus software says the file is malicious, the program must give some details. We might be able to help you if you post the details here (filename etc.)
You really need to replace it with the original. This is quite easy if you have your orginal Windows install disc.
Run the following from the command line:
That should find the file causing the problem and revert it back to its original state.
Unfortunately, sfc (System File Checker) isn't perfect and you might need to do it manually by first booting into safe mode, replacing the file in %SYSTEMROOT%\dllcache then deleting the file from %SYSTEMROOT%.
Note: %SYSTEMROOT% is Windows\System32. Just type it into the address bar though because dllcache is hidden by default.
There is also the possibility that the .sys file is just an addition and not a replacement in which case you can do the same as above, just deleting the file in dllcache instead of replacing it.
Also, I take no responsibility if you hose your system by deleting the wrong stuff!

can't the anti virus delete it? try it from the dos mode then... use an windows xp cd or windows 98 cd to boot from the DOS mode. good luck
You can try to use this file killer program Killbox! from: http://killbox.net/
This software can delete any file that runs when your system starts. However, you will still need to kill all other files related to that sys file if that file keeps reappearing after using the file kill program. Don't worry this program works and best of all it's FREE

Why not try booting your system into safe mode (try hitting F8 when its booting up, just after the BIOS stuff)? You should be able to delete it then.
Hi filet
Now that you have checked the file is not really a system file, you just need to delete it.
Safe Mode is good and simple way to delete things that can't be deleted when Windows is running normally, but doing a Clean Boot is an excellent alternative.
Please consult my post “How to Run a Full Computer Backup or Virus Scan Efficiently” on the Computers -> Software forum (http://www.frihost.com/forums/vp-679307.html). If you run your virus scan as I suggest, for sure you will be able to delete any infected files.
Good luck
