If you find a file on your computer that you don’t recognize, you may worry that it’s malware. Before you panic, check out Bit9’s free FileAdvisor to learn if the file comes from a legitimate source.
Bit9 tells you the suspect file’s source, including a hyperlink to the website. If Bit9 doesn’t list a source, then kick your defense mechanisms into high gear. Make sure your anti-virus program is up-to-date, run a scan of your drive, and ensure you’re firewall is running.
