The shown message box states the following:

*Your Windows (Microsoft) Computer has been blocked*

Windows System Alert!!

Know that Microsoft does not provide any unsolicited help with PC or technical issues, unless you initiate it. That means, that Microsoft will never offer you help – you have to ask for it. Unfortunately, some scams are very clever and still work to this day.

One of the most recent scams that you may have seen or become a victim to is one that looks like a Google Chrome Warning for a phishing site or malicious activity. The trick is to fool you that Google is blocking access to the website you are trying to reach. And you think you need to reach that site in the heat of the moment, as one of the most recent domains was called “securityagainstwannacry.com”. As if there would be an official site devoted to stopping the WannaCry ransomware threat that Google would block.

You can see an example in the pictures below, with the full text contents afterward:

Your computer has been blocked
Your computer with IP address – has been infected by the Virus RDN/YahLover.worm!055BCCAC9FEC — Because System Activation KEY has expired & Your information (for example, passwords, messages, and credit cards) have been stolen. Call the Technical Support number +1-844-760-5091 to protect your files and identity from further damage.

The following data will be compromised if you continue:
1. Passwords
2. Browser History
3. Credit Card Information
The virus is well known for complete identity and credit card theft. Further action through this computer or any computer in the network will reveal private information and involve serious risks.

Cybercriminals which are on the other end of the phone line will try to keep you on the line as much as they can. They will lie to from how you shouldn’t tamper with your computer device except if you are instructed, to how you need to provide personal information. Do not give any information and do not trust anybody on the other side of the line.
