Microsoft has a high quality virus removal program called the Malicious Software Removal Tool. AVG is another company known for its top-notch virus removal programs, and Malwarebytes also has a great virus removal tool.
Microsoft's Malicious Software Removal Tool is an antimalware utility tool for computers running various Windows operating systems. The program prevents, detects and removes many kinds of malware. AVG's antivirus program is another good option for protecting a computer, but it isn't quite as comprehensive as Malwarebytes' program or Microsoft's Malicious Software Removal Tool. Malwarebytes has many reputable virus removal tools, including the Malwarebytes Free Anti-Malware program.
