how to get rid of NTOSKRNL-Hook Trojan Horse

Asked by: kdschool

I have NTOSKRNL Hook that shows up when I run current version of McCaffee that is up to date.  I also ran Maleware Bot and it does not locate this.  It only shows up on Virus Scan.  Says it's removed but shows up everytime I run it.  It's doing something weird on my start up.

Please help in how to get this off.

Run your antivirus/antimalware scans in Safe Mode. Prior to that though, disable System Restore.
System Restore. Directions can be found here:
http://support.microsoft.com/kb/310405
Once System Restore is disabled, reboot into Safe Mode (F8 at startup) and run a scan.
Example with solution of your issue can be read about here.

I followed exactly what you said and when I ran the virus scan in safe mode it did not find or clean the virus.  I re-booted and ran it again and it was still there.  Saying it could not remove it.

if you tried Malwarebytes and the infection is still there & the infection is not showing up during safe mode scans

superantispyware did the trick as per this post on Mcafee forums

http://forums.mcafeehelp.com/showthread.php?t=227241

if the problem persists, please use combofix as already suggested.

this one know matter how many times I install and execute closes will not execute. Give error message.
Spyware Doctor Setup has encountered a problem and needs to close. We are sorry for the inconvenience.

Please note that the proper place to download ComboFix is:
 
http://download.bleepingcomputer.com/sUBs/ComboFix.exe 
 
That website that ends with ".org" should never be recommended.
 
Thanks,

Could you please rename Combofix & Superantispyware programs before running them ? 

preferrably download on a clean machine, rename them first then transfer to the infected machine.

Hurrah!!!  It fixed everything doing it this way.  I had to rename the combofix to execute it.  Thank you so much for hanging in there with me on this.
