In the event that your PC has been infected by some malware and you're having issues with your antivirus or anti-malware application removing it, it might be necessary to use a program like RKill to actually kill the process so that it may be removed.
With RKill, you are normally able to forcefully stop running processes which wouldn't be possible with Windows Task Manager. RKill may also perform some system optimizations so that you antivirus program may continue with quarantine or removal.
It's worth noting that when you use RKill to combat malware, it won't actually remove or otherwise quarantine the file but merely stop it if your antivirus program is unable to. It may also be helpful if whatever malware you are infected with has compromised your security software.
RKill isn't a replacement for antivirus or anti-malware, but it can be a useful tool in your arsenal against malicious software.
