RKill

One way that malware protects itself is by avoiding detection by antivirus software and other antivirus tools that are installed on the PC. Sometimes it does this by blocking the software. RKill is a lightweight program that scans your Windows operating system for these kinds of processes and temporarily disables them so that you can properly rid your PC of any malware.

Keep in mind, this application doesn't remove malware of any kind; it just stops the malware processes. This means once you restart your computer, the malware in question will run again if it is able to. Basically, RKill is a great supplemental application and should be used along with the antivirus software you have installed.
