What is Koobface?
The Facebook video virus, also know as Koobface entices unaware Facebook users with a video attachment. In the message, the virus entices you with either “check out this celebrity video," or “my friend catched you on a hidden cam," and even, “Is this you! Hi my Friend!" You may also receive a video that entices you to view it because it actually names the celebrity like Paris Hilton.
When users follow the instructions to download Flash Player, the self-replicating worm Koobface virus infects the computer with malware including web hijackers, ad rotators, social network propagation components, fake antivirus programs and data stealers.
If you see something like the screenshot to the left, your best bet to ignore it, because although it looks like one of your Facebook friends sent it, they haven’t. Some Facebook users also receive accusatory emails from friends who inquire as to why they are sending spam video messages. Because the virus gets into Facebook privary walls, it does indeed look to others like the message came from you.
If that weren’t enough, Koobface also displays Captchas that prompt you to enter codes or letter quickly or else your computer will shut down along with error messages such as “error installing codec." Others are finding extreme slow times including network and browser searches, popup ads and antivirus programs not previously installed.
Indeed the Koobface Facebook video virus is dangerous and now some experts like PC Tools says it’s also been seen on Twitter and MySpace.
If you’ve been caught unsuspectingly, what can you do to remove the Facebook video virus?
