What is “This computer is blocked” virus alert?

“This computer is blocked” is a fake virus alert that makes people believe that there is a virus or malware or their system. It would raise a phony warning that Windows has detected the unusual activities on your system and to resolve that you need to contact to the given number. The number belongs to the cybercriminal behind the scam. Upon contact, he would manipulate the victims to steal their personal pieces of information—thus fulfilling their aim of identity theft. They would also ask for payment in the form of a one-time fee or subscription to a fake support service.

The dubious webpage displays the following message:

VIRUS ALERT FROM MICROSOFT

This computer is BLOCKED

Your computer’s registration key is Blocked.

Why we blocked your computer?

This window’s registration key is illegal.

The window is using pirated software.

This window is sending virus over the Internet.

This window is hacked or used from undefined location.

Apart from displaying this message, the scammers also download various files in the background, causing the browser to crash. This makes users believe that something is definitely wrong with their system.

It is essential to know that Microsoft has nothing to do with such scams. Their warning or error message never includes phone numbers, and they encourage their consumers to call them.

Moreover, Microsft does not send the emails or call you to get the personal and banking information to fix the system.

What is a Phishing attack?

A phishing scam is a social engineering attack carried out by playing with the victim’s psychology. Usually, cybercriminals use it for stealing the victim’s personal data like credit card details, ATM PIN, or net banking password .

In phishing, the users are sent or redirected to dubious links by sending them intruding advertisements, pop-ups, messages, or emails. The users are then psychologically attacked by making them believe that they are one from the many users to win a huge award.

In some cases, like “This computer is blocked” virus alert users are threatened psychologically by making them believe that something is wrong with their computer, and to fix it you have to provide fees.

Why Did I get “This computer is blocked” virus alert?

You have received the “This computer is blocked” virus alert because your browser or system has been infected by a malicious program like browser hijacker or adware. It may have also appeared because you have visited an infected website.

When you install any bundled software, it carries another program other than the primary one. That another application can be a malware carrier responsible for phishing attacks.
