This is not a new type of scam. For years now different types of Trojan viruses have been embedded in various web pages and links. If you click on the page or link you're taken to malicious websites, which install a virus. The virus then quietly sits on your computer, stealing passwords and account details until it has enough details to empty your bank accounts.
This scam took two very popular forms this year. The first was a link sent in an email pretending to be from Facebook, and inviting you to click the link. When you did, it would install the virus and then send the link to your Facebook friends.
The other form was a page with a fake YouTube video in the background, which claimed to show Rita Ora's famous wardrobe malfunction. However, the site prompts you to enter your Facebook details, so you can see the video and 'personalise your experience'. The criminals then have access to your Facebook account.
