So, what can you do to keep yourself safe from this Koob-faced villain? The steps are nothing you haven't heard before: Keep your antivirus software up to date, and use some common sense.

Antivirus software will alert you if you click onto a site that's known to host malware -- and that's exactly where these Koobface links want to take you. The easiest way to stay safe, then, is just to be cautious in choosing what you click.

If you see a link that looks questionable, even if it's from someone whose name you know, don't follow it. And if you find yourself on a Web page that's asking you to download a software update, don't do it. Instead, close the window and go directly to the software vendor's own Web page to see if the update is the real deal.
