This article in our series focused on Microsoft’s free security tools is on a tool called the Microsoft Safety Scanner. The Microsoft Safety Scanner is a free stand-alone virus scanner that is used to remove malware or potentially unwanted software from a system. The tool is easy-to-use and packaged with the latest signatures, updated multiple times daily. The application is not designed to replace your existing antimalware software, but rather act as an on demand virus removal tool in situations where you suspect your real time antimalware software might not be working correctly. If the antimalware program you are running regularly becomes disabled without your knowledge you may have malware or rogue security software on your system. Running the Microsoft Safety Scanner can help detect and remove malware or potentially unwanted software that may be disabling your real time antimalware software.
