Internet security company Sophos has issued a warning against visiting a video link circulating on Facebook.
The Guardian has reported that Sophos is advising users not to visit the link, as it will lead to malware being installed on the victim's computer.
According to a video posted by the security company, the link comes with a wall post "this is without doubt the sexiest video ever! :P :P :", along with a video entitled 'Candid Camera Prank [HQ]'.
Users trying to view the video are redirected to a fake Facebook application page which informs them that their video player is 'out of date', prompting users to install a file.
The moment the users download the file, the same link is posted on the walls of their Facebook friends, helping to spread the malware virally.
In a statement to The Guardian, Graham Cluley of Sophos said: “Judging by the number of messages posted on Facebook, thousands of people received this attack. If you were one of them, you should scan your computer with an up-to-date antivirus, change your passwords, review your Facebook application settings.”
