What is CRITICAL WARNING License Key Revoked? Can CRITICAL WARNING License Key Revoked messages be caused by malware? Is your computer infected?

The phone number may vary, but it is there to let you believe that is for contacting support technicians who work for Microsoft.

CRITICAL WARNING License Key Revoked – What Is It About?

CRITICAL WARNING License Key Revoked message can appear in your browsers as a result of third-party installations and freeware packages. Surfing the Web and reaching new and unverified websites, clicking on advertisements or redirects related to suspicious links are other ways because of which the scam page can appear. Freeware applications, regarded as PUPs (potentially unwanted programs) could also be helping to spread the scam.

CRITICAL WARNING License Key Revoked message is hosted on a website that pushes this technical support scam. The scam has a few related pages with different texts supporting the idea of your PC being infected. Different phone numbers are used for each page of this scam. Cybercriminals who are behind the telephone will try to trick you into thinking that they are part of some technical support team, working for Microsoft. The thought of your computer being infected with viruses and that the support hotline is your only salvation might scare you into calling the phone number provided on your screen.

Here is what one of the text related to the scam says:

Windows
CRITICAL WARNING!

This is how the screen looks if you enter the unlock key 00000-Z0006-000B1-00000-000N0:

CRITICAL WARNING license key verified

As you can see above, the message labeled as CRITICAL WARNING License Key Revoked is a fake one, although it can be made to look like it is from Microsoft by changing the font, design and other such tweaks. Do not believe the message and know that it is a blatant lie.

The phone number is not free as promoted on the website, and even the shortest call may be very costly. The con artists can present themselves as Microsoft employees, but they are NOT and will only try to extract personal information and financial data from you leading only to complications.

In conclusion, you should be wary of what information you give out and should do a scan with a security software to make sure that your system is clean and nothing else but the browser is causing the messages to appear.
