Rkill
Malware Process Terminator and Anti-Malware Assistant. Stops the process so you can run Malware cleaners.
WHAT IS RKILL?
Rkill is created by Microsoft MVP Lawrence Abrams (also known as Grinler in several security forums). Rkill is malicious software process killer and anti-malware assistant because it will terminate the active processes of malware that is blocking your anti-malware, anti-virus, Task Manager, Process Explorer, Registry Editor, browsers and any other programs in loading. When it finished unloading or terminating malicious processes associated to rogue or malicious program, you can proceed to scan and clean the system using anti-malware or anti-virus program
It's available in a number of downloads.
NOTE:
You do not need to run each file format of rkill, use one at a time; if the first one will not run at all (if the command prompt window displaying rkill is in the process of terminating the malicious processes is not shown).
You may need to try and run the file a few times if it doesn't run, if that doesn't work, move on to the next file such as the .com.
Try the next file format.
If you using Windows Vista or Windows 7 with UAC enabled, you will need to right-click rkill and choose to run as admin.
The file size is less than 300kb only (257kb to be exact). To use Rkill, simply execute rkill.exe. You should see the command prompt window indicating that rkill is terminating known malicious processes. The command prompt will disappear when it finished and you will find ncmd.cfxxe, rkill.reg and pev.exe which are created by rkill. If you will execute rkill.exe again, those files will be removed by rkill. You can also manually delete rkill and other files it added after you’ve finished in using or cleaning the system.
