If you see this message pop-up on your screen, you are in trouble. You’ve either visited a bogus website, which is showing you this message, or there’s a nasty parasite installed on your Mac. The scam message in question is known to slow down browsers, and also prompt victims to install other unreliable software, in order to solve the problem. Do not trust this message! It will try to trick you into exposing your personal information! What you need to do, is find the PUA (potentially unwanted program) responsible for the appearance of this scam pop-up, and thoroughly remove every trace of it from your Mac!

How it is distributed

Unwanted programs are known to get featured in some installers as ‘additional’. And, if the user fails to notice their existence, they’ll just get automatically installed along with the program the user actually wanted to have on their computer. This is why you need to be very careful when you’re dealing with software installation. Pay close attention to every step, and if you see any optional installations you’re not familiar with, it is always best to uncheck the boxes next to them and proceed with the installation. To make sure you have full control over the process, we suggest choosing the Custom or Advanced option in the Setup Wizard.

How it operates

The “A Website You Visited Today Has Infected Your Mac With a Virus” message uses scare tactics, to make users do its bidding. Such scam pop-ups are known to redirect the user to pages which promote some kind of useful AV software. You may be prompted to either buy the app straight away, or use a free scanner, only to be made to buy the full version afterwards. If you let yourself get tricked, you will be letting other malicious software on your macOS, which may do more than just spam you with adverts. This PUA is a real threat to your private data and your Mac’s security. Don’t let cyber criminals obtain valuable information or cause serious damages to your computer! The sooner you get rid of this nasty parasite, the better!

Staying safe from “A Website You Visited Today Has Infected Your Mac With a Virus”

Apart from having a reliable AV software installed on your Mac, there are other things you can do to ensure your device’s safety. We highly recommend you to:

  • Pay close attention when you install third-party software, especially torrent files, so you don’t install shady additional applications that you don’t want. In most cases, that’s how malicious parasites are able to infect your computer;
  • Read any Terms and Conditions you see, so you know exactly what you agree to. The last thing you want is to unknowingly give permission to a nasty virus to infiltrate your Mac;
  • Follow links that lead to trustworthy sites only;
  • It is best to visit only reliable and official websites. You never know what dangers might lurk behind an unfamiliar site;
  • No matter how attractive an ad is, if you are not familiar with the website it redirects to, it might be best to steer clear of it and not click;
  • Always check the sender’s email address before opening a message. If it states that it’s from an official company, compare the email with the one given in their official page. If there is no match, delete the message, since it most likely is fake and has malicious aims;
  • Don’t open email attachments from unknown senders. More often than not, such files carry infections that can seriously damage your computer.
