Facebook users should be wary about the lastest version of the nefarious
Koobface worm, which is spreading widely across the popular social
network, says antivirus firm Eset.
The worm arrives in the form of a message from a friend claiming to show
erotic encounters captured by a hidden camera. You'll be asked to
download a special video player to view the video. Don't do it. You'll
trigger an automated program that will send copies of the same viral
message to all of your friends, while turning full control of your PC
over to the attackers.
