There is a new worm propigating itself throughout the Facebook and Myspace social network by using the messages function on both websites according to News.com.

The messages look like they contain links to video clips. When clicked on they prompt the recipient to download an executable file that purports to be the latest version of Flash Player. Instead, it is the worm itself, infecting yet another victim.

When infected machines log onto the social networks the next time their computers automatically send the malicious messages out to new victims grabbed from the friend list, said Ryan Naraine, security evangelist at Kaspersky.

So next time you receive an message from a friend with a link to check out a new video or picture be careful when you follow the link. If it asks you to download a file, use caution and make sure your anti-virus program is up-to-date.
