You may have already seen it. Several times. The Facebook malware virus scheme that started to appear a few months ago resembles an old “hahaha” Facebook virus that showed up a couple of years ago. It's a FB instant message on Messenger that includes your name, a link to a “video” and question “Is that you?” Usually, a “video” link appears to be a YouTube link, but it typically ends with the malicious login page seeking to trick you into passing your Facebook account to the bad guys. And it's an equal opportunity invader on desktops and Smartphones.
The “Is that you” Facebook virus can lead you to numerous places which are considered as unsafe; some with commercial spam and malicious content, and even the danger of access to your personal info. A clue that bad guys have gotten through your account it is through your friends.
According to 2-Spyware.com, as soon as some of your friends tell you that you are sending messages via Messenger asking "Is it you" in this video Facebook virus, immediately scan the system with professional security software, such as Reimage, SpyHunter 5 or Malwarebytes. Then, immediately change your Facebook password.
It’s also advisable to report your friends that your account might be hacked and that they should now open suspicious messages that are sent via your account to them. To avoid this “phishing” in the future, you can take action through your account settings.
