Think your computer might have a virus? The Microsoft Security scanner is a free download that will scan your computer and help you remove viruses, spyware, and other malicious software.

Download Microsoft Safety Scanner

The scanner is not a replacement for antivirus software. It contains the latest anti-malware definitions, but it works with your antivirus software. The Microsoft Security scanner expires after 10 days, but you can download the newest version again for free. Antivirus software like Microsoft Security Essentials is also free, but provides real-time scanning and does not expire after 10 days.
