Virus developers are still targeting social networking users to distribute the virus. The “friendly nature” of the social networking sites makes it easier to spread the worm quickly. Most users won’t suspect as it’s a virus as it usually comes from a trust worthy source.

Koobface virus sends virus to the facebook friends list asking them to checkout one of the latest movie. Clicking on the link asks the user to download a plug-in to watch the movie.(or will prompt as adobe flash player update). If the user accepts it, then its done, Koobface got the next victim and makes the way to the next set of friends.

Be very careful while watching any movies linked from social networking sites. Never ever update the so called “plug-in” even its prompted on a trust worthy website. (So many look alike sites are there. Many of them will look like the so popular youtube). If its really an upgrade needed, take the pain; go to adobe.com and grab the latest update.
