RKill is a free software utility developed by Bleeping Computer, which is designed to terminate known malware processes running on a Windows computer. RKill is often used as a first step in the process of removing malware from a computer.

RKill works by scanning a computer’s processes and services and identifying any known malware processes that are running. Once identified, RKill attempts to terminate these processes, which can prevent the malware from continuing to run and potentially infecting other files or spreading to other computers on the network.

It is important to note that RKill is not a full malware removal tool and should be used in conjunction with other anti-malware software, such as an antivirus program or anti-malware scanner, to fully remove any malware infections from a computer. RKill is often used as a preliminary tool to stop malware processes before running a full malware scan or attempting to remove the malware manually.

Overall, RKill can be a useful tool for quickly identifying and terminating malware processes on a Windows computer, but it should not be relied on as the sole method for removing malware infections.
