This virus is spread via email, usually in the form of friends on your virtual social network inviting you to watch a video.
Once you naively click on the URL link inside the email, the " Koobface " virus will immediately ask you to update the Flash audio-visual software to view the video.
Then the virus lies there, inside a file called " flash_player.exe ".
According to Kaspersky Lab - a security firm that is working closely with Facebook, the Koobface virus will turn a victim computer into a zombie (the computer that control has fallen into the hands of hackers) to create new botnets.
According to the explanation on McAfee Security's Blog page, when Koobface infects your computer, it will activate a download service called Security Account Manager (SamSs).
Next, SamSs will proxy all HTML data in and out, steal data from familiar search engines, then hijack them and lead users to strange search sites.

To not be turned into reluctant victims of Koobface, always be alert and watch out for any risk of fraud. You can easily identify phishing emails through their titles.
As noted by Kaspersky, please quickly delete the following emails: Paris Hilton "swing" dwarf on the street ;Candidates are caught downloading scores through the Internet ;You must see this !!!!;My friend sneaked my camera ;Funny moments of stars .
Some serious misspelled email titles, such as: yoour blushingg afce is so funny!Checkk out . These are clear signs that you are being attacked.
Facebook itself has posted user instructions on how to delete Koobface virus: activate the latest antivirus software immediately and change your Facebook password.
The attack took place just weeks after Facebook won the $ 873 million lawsuit, against some hackers accused of hacking Facebook user accounts to distribute spam.
Facebook is currently the most popular virtual social network in the world with over 120 million members participating.
