What is the message YOUR COMPUTER HAS BEEN BLOCKED? How can you stop seeing it?
YOUR COMPUTER HAS BEEN BLOCKED is a message that accompanies quite a few tech support scams, as well as some ransomware viruses. Those scams can appear on your PC in a lot of ways, the worst of which is due to a Trojan horse. Most of the scams have websites spreading them, which can lock you out of your browser to a point you cannot interact with it.

Fortunately, those scams do not encrypt files. Every scam uses one or more phone numbers. You should carefully read this article to see how to remove such types of malware.

YOUR COMPUTER HAS BEEN BLOCKED – Spread
This tech support scam has many variations. That’s why the YOUR COMPUTER HAS BEEN BLOCKED message can be displayed on your computer due to different spread methods. A common way for it to appear is when you are surfing the Web. When you visit websites which are suspicious and of unknown origin, they can spread the scam via redirect links or advertisements. Clicking on the ads or redirects is not always necessary as any interaction with the site might trigger them. Sometimes, just by leaving a website open can drop malicious files on your computer which load other sites supporting the scam. Phishing websites can make the message of the scam appear, too. It is easy to land on such sites because of a single spelling mistake in a URL.
The worst case scenario that can happen to show you the YOUR COMPUTER HAS BEEN BLOCKED message is if you have a Trojan horse present in your system. The Trojan horse may have installed itself using some of the spread methods mentioned above. In other cases, you may have installed it, without realizing that. You may have thought that you are installing an application which is useful. Many such third-party programs come bundled with other freeware and supposedly useful software. Unfortunately, some can secretly install additive features or even malware. To avoid additional content being put in your PC by such installer setups can be managed if your find Advanced or Custom options in the setup.
YOUR COMPUTER HAS BEEN BLOCKED – Details
YOUR COMPUTER HAS BEEN BLOCKED is a message that can appear on your screen from a tech support scam. The message can appear in a website page, notification, an error or a pop-up message. A phone number is always provided, which is supposed to be a number for contacting support technicians from Microsoft or another reputable company from the security sphere.
In some cases, you can experience your screen or browser being locked or an audio message being played for maximum effect. The file is usually played via the Adobe Flash Player or a similar plugin. The audio message can be applied to lots of such websites, especially if the number is not said in the audio file. The voice of a woman or a man urges you to call the number. You can hear such an example from the audio sample right here:
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 screenshot below:
People who work in IT or are tech savvy will all tell you the painful truth, that Microsoft does not have a support call line. Knowing that information and seeing a phone number on a copycat site is a dead giveaway, but not for people who are unaware of that fact. You can easily fall victim to such a scam, especially when you are bombarded with pop-up messages such as YOUR COMPUTER HAS BEEN BLOCKED non-stop. The most common variant of such a scam employs a one-page website with a picture background which is a snapshot of the real Microsoft site as seen in the above image. There are two generic messages written inside the pop-ups:
** YOUR COMPUTER HAS BEEN BLOCKED **
Error # 268D3
Please call us immediately at +1-844-730-8222
Do not ignore this critical alert.

– 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.
The second message varies a bit and actually states Your Windows (Microsoft) Computer has been blocked. That exact same message can be seen in the third type of this scam, this time being loaded as a notification or an error box directly inside your desktop computer:
The error box is loaded without the requirement of an Internet connection, and it is displayed, because of malicious software, files and registry entries related to the scam are inside your computer. A Trojan horse is not excluded to be managing those files to remain persistent on your machine, so whatever action your try to perform on your PC, the message to be stuck there. That can also lock your desktop screen, and you could be unable to interact with your computer device just like ransomware viruses do.
The locking of your screen may or may not happen depending on the files residing on your machine and the type of tech support scam. That brings us to the fourth and final variant (for now) of the YOUR COMPUTER HAS BEEN BLOCKED message. Here, the website pushing the scam will lock your browser, and the word blocked in the message will be turned into locked. The website will look exactly like a legitimate Google Chrome Warning for a phishing site or malicious activity. You can see an example in the picture below:
The full text on the site says the following:
Your computer has been Locked
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.

The following data will be compromised if you continue:
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.
With that, the main four variants of the YOUR COMPUTER HAS BEEN BLOCKED technical support scam are exposed.

YOUR COMPUTER HAS BEEN BLOCKED – Update July 2017
In July 2017, the scams that use the YOUR COMPUTER HAS BEEN BLOCKED message to scare people have increased. Typically, technical support scams use the message to try and trick you that you have a virus on your computer device. One of the latest trends around is the lie that you have the WannaCry virus, which became popular in the middle of month May, and kept being the theme for a lot of malware since then. New websites representing tech support scams are being created, which spread messages with new telephone numbers for you to call alleged Microsoft technicians, claiming that only they can fix your computer. These website pages are most commonly phishing pages that look like either the front page of the Microsoft official website or Google’s security warning that informs you about malicious domains. Be careful, do not call such numbers for unique support technicians, do not provide personal information and do not believe a browser detecting viruses on your PC unless you check with a security program first.
Update July 2017. Unfortunately, these tech support scams continue to spread in the wild, infecting users via various methods.

One of the most recent reports by a victim clearly shows that users are easily tricked by the displayed message claiming their computer has been blocked.
