In some cases, a malware that have infected a machine might execute processes that disable the computer's antivirus software and keeping it disabled as long as that process is running. Rkill is a free software that can be used to identify known malware processes running on a machine and terminate them. Note that this tool does not remove viruses, it just stops their processes so that the user will be able to run a scan with their antivirus or manually clean the  malicious file. If the malware is not cleared, the terminated processes will start running again when the computer restarts.
