Your Windows Computer Has Been Blocked – Spread

This tech support scam has been spread by different methods as it has many variants. That’s why the Your Windows Computer Has Been Blocked message can be displayed on your screen without you knowing how it got there. Usually, visiting a malicious website can trigger the message or the site itself could be displaying it. Clicking on ads and redirects is another way of distribution. Mistyping a domain name can also be a trigger for the message to pop-up, or you to land on a scam site.

Here are the detections on VirusTotal of one scam site, showing that it is malicious:

You could still see the Your Windows Computer Has Been Blocked alert without any of the above occurring. That is because the trigger might be a Trojan horse downloaded to your system, due to the installation of a bundled app. The Trojan horse may launch ransomware with a similar scare alert.

Your Windows Computer Has Been Blocked – In Depth

Your Windows Computer Has Been Blocked is a message that can appear in multiple ways to your screen, usually caused by a tech support scam. That message has been seen to appear in a website page, as a notification, an error, a pop-up message or simple text on the main page. A phone number is always provided, suggesting or scarring you into contacting alleged support technicians from Microsoft or a similar well-known company.

In lots of the cases, your screen or browser is being locked and even an audio message is being played to scare you further. You can hear an example recording of such a message below:

Many of the websites related to these tech support scams are made to look like the official Microsoft website. See an example of a fake Microsoft site from the below screenshot:

The shown message box states the following:

*Your Windows (Microsoft) Computer has been blocked*

Windows System Alert!!

Call Microsoft At 1-888-243-3533
You have been blocked from accessing the Internet.
Private and financial data is at RISK:
– Your credit card details and banking information
– Your e-mail passwords and other account passwords
– Your Facebook ,skype,AIM,ICQ and other chat logs
– Your private & family photos and other sensitive files
– Your webcam could be accessed remotely by stalkers

It is Required that you call the number above and get your PC inspected before you continue using your internet, especially for Shopping or Banking.

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.
Call Technical Support Immediately at 1-844-760-5091
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.
