Koobface is the latest virus that has attacked the social networking phenomenon. Top social networking websites like facebook and myspace are the places where this thing has done nothing but mischief.

How Koobface Infects a Computer?
Basically if you are using facebook you should watch for automated email messages that display either an insulting message or some thing very tempting about you. Messages like, "you look funny in this video" or "you look so stupid in this pic" can be used to persuade somone to click on the link attached, this called 'Social Engineering'. Once the user clicks on them it takes you to a video which doesn't play and they ask you to download certain codecs which can be a 'flash_player.exe' file.
If this file is downloaded, your computer becomes open to Koobface malware. It downloads a file 'tinyproxy.exe' which hijacks your PC. It can even alter search results from Google, Yahoo etc and redirect you to websites selling malicious softwares.
