If you frequently download files from suspicious sites, it’s probably worth it to check for viruses Before you download, instead of waiting to see if your regular anti-virus software will catch it after you download.

The solution? You can use the Dr.Web plugin, which will add an item to the right-click menu to allow you to scan any web page or download link using their online virus checker.

Let’s take it for a test drive… I decided to scan the Dr.Web Firefox plugin with Dr.Web, just to see what it would say.

Looks like it’s clean! (shocker)

Keep in mind that no anti-virus software is absolutely perfect or will catch every virus, so this isn’t a substitute for using a proper anti-virus software. You should also still be careful where you download files from.

This plugin will also not work for webmail attachments. I tested this on Gmail and it didn’t work,¬†which isn’t necessarily a bad thing, because it means your attachments are private.
