A Facebook virus is circulating in the North Wales area.
Users of the social media site are receiving a seemingly innocent message from people on their friends list with a video link attached, which claims to be about the receiver.
But when opened, the video redirects to a false YouTube page where the user is prompted to download a file to view the video.
However, there is no video.
This malware can post your profile picture along with a URL and a video in a message making it look like your friend has spotted a video of you.
Instead those who do follow the instructions and complete the request unwittingly download a virus which in turn spams the users friends list with the same link.
Although it is unclear exactly what this virus can do, it is thought that cyber criminals may also use this or similar hoaxes to trick people into downloading malware or installing malicious apps and browser plugins.
There have been reports that some users have been unable to log out of their accounts after mistakenly downloading the virus.

But there are steps you can take to avoid being compromised.
If you receive one of these messages, DO NOT OPEN it and inform the friend who appeared to send the video that their account has been hacked.
However if you do find that your Facebook profile has been compromised by the scam, you need to secure your account as soon as possible.
Be sure to change your password and run an activity check to spot any suspicious activity on your page.
You can also remove any downloaded malware by going into Facebook Settings & Apps, Websites and Plugins & Select Disable to protect your account from unauthorized access of third party apps.
It is also recommended to run any anti-virus or malware programs to rid your device of any bugs that may have been downloaded to your system as a result of the download.
