How about the Fake anti-virus scam? I’m sure we’ve all seen at least one of these message on our screens: “You have been infected! Download this antivirus right now to protect your computer!”. Many of these pop-ups were very well created to resemble actual messages that you might get from Windows or from a normal security product.
If you are lucky, this is nothing more than an innocent hoax that will bother you by displaying unwanted pop-ups on your screen while you browse online. In this case, to get rid of the annoying pop-ups, we recommend scanning your system using a good antivirus or anti-malware product such as malwarebytes.
These fake virus scanners can install a Trojan or a keylogger. I hope you watched the video where I discussed keyloggers so that you understand the dangers of it. As I said before, usually these fake antivirus programs install ransomware, and you don’t want that, believe me.
