The New York Times reports a new virus has appeared in the Internet that poses as a video from one of your Facebook friends. Over 800.000 Facebook users have already suffered from the virus. 

The virus appears as a link in an email or Facebook message that tells you someone has tagged you in a Facebook post. When you go to Facebook and click the link you’re sent to a different URL-address and told to download a browser extension or plug in, in order to watch the video.
After the plug-in is downloaded the intruders can gain access to everything you have stored in your browser, including accounts with saved passwords in Facebook, Twitter and other social networks.
It is not easy to get rid of the “extension”, because it blocks access to the settings of your browser and disables access to the websites of antivirus companies. According to the researchers, who are considering by the comments in the code, the virus was created by hackers from Turkey.
The virus has been spreading at a rate of about 40,000 attacks an hour and has infected more than 800,000 people via Google’s Chrome browser. Google is aware of the attack and has already disabled the extensions that allowed it. Facebook also detected the virus and is working to clear the links.
