MHR extension for Firefox checks downloaded files with multiple anti-virus

Team Cymru (pronounced “kum-ree”) has released an extension for Firefox browser , called MHR, which allows you to quickly check your downloaded files against multiple anti-virus and anti-malware products with just one click.

After installing this add-on, a ‘Check MHR’ link appears unobtrusively in your downloads window. Click the link to check the respective file against Team Cymru’s Malware Hash Registry (MHR) service.

A checkmark indicates that its malware database has no malware history of that file.

If a file does have malware history in its database, a message will be displayed indicating what percentage of many anti-virus products reported this file as malware, and a red ‘x’ icon will be displayed.

In the event the download is identified as malware, it can be deleted rather than installed.

This extension does not replace your antivirus software. Rather, it is a supplement.
