Microsoft Safety Scanner
Microsoft Safety Scanner is a free downloadable security tool that provides on-demand scanning and helps remove viruses, spyware, and other malicious software.
It is designed to work with your existing antivirus software in the case of an infection getting through.
The Microsoft Safety Scanner is not a replacement for using an antivirus software program that provides ongoing protection so make sure you have an Anti-Virus programme running, there are many free ones available, and that you update it regularly.
Microsoft Safety Scanner expires ten days after downloading so it is always as up to date as possible. The link will take you directly to Microsoft to be sure you have the latest version and you can choose either the 32-bit or 64-bit option.
