How Did I Get Infected by “Access to this MAC has been blocked”?

Since “Access to this MAC has been blocked” has been classified as a pop-up browser scam, its method of distribution is related to unsafe browsing habits. Browsing the web hides its potential risks, especially if you’re visiting suspicious websites and your computer lacks specific protection. Websites can be hijacked with advertisements and redirect links, and you can be redirected to suspicious scam pages which could trigger various fake virus warnings.

Freeware applications and PUPs (potentially unwanted programs) could also distribute tech-support scams, and could cause the scareware message to appear in your browsers. Free download websites usually feature tons of third-party installations and bundled installers – a practice which is done with monetizaton in mind.

“Access to this MAC has been blocked” is just one example of tons of fake pop-ups triggered by tech support scams. Note that different phone numbers may be promoted, and the message itself may be different. Of course, the purpose of every such message remains the same – to trick you into performing an action which directly puts your computer at risk. Both Windows and macOS users are affected by similar tech support scams, as well as iPhone and Android users.

“Access to this MAC has been blocked” – What Does It Do?

Scammers are using fake virus detections and warnings to create the sense of urgency and to make you dial a specific phone number or perform another action that exposes your online security. There’s no telling what could happen next, especially if you permit remote assistance or reveal sensitive information, such as your payment data.

To make their scams more believable, scammers tend to feature the logos of trustworthy companies such as Microsoft, Google, and Apple, or anti-virus software companies such as McAfee and Avira. However, seeing the logo of a popular company (in this case, Apple) shouldn’t trick you in any way, since these companies do not deploy such methods to alert their users of issues. This is what tech support scammers do in their desperate attempts to trick users into performing specific actions.

Note that you may even get a phone call from tech support scammers. Scammers that are on the other end of fake tech support telephone lines will try to trick you into believing that they are part of some sort of an official tech support team of Microsoft or Apple. Of course, that’s a lie. The only truth here is that scammers are professional in what they do. There are whole call centers that recruit people for the role of a bogus tech support representative. It is a lucrative business, and users should be smart enough not to fall into the trap.

Is “Access to this MAC has been blocked” a Virus?

No, this is not a virus but rather a scam that wants to make you believe that your system has a virus. In this particular case, the scammers are trying to trick you into believing that a backdoor trojan has infiltrated your system. Don’t worry, as this is just a scareware approach to push you into performing a specific action, like downloading a rogue software program. Refrain from interacting with any of the content that this scam triggers.
