What does "Microsoft has locked your computer" mean?
Even "Microsoft security warning", "suspicious connection", "Firewall violation detected', and many others, 'Microsoft Has Blocked The Computer' is a fake error message that displays a deceptive website.
Research shows that users are often redirected to this website by various potentially unwanted programs (PUPs), which often infiltrate systems without permission. PUPs not only cause redirects, but also misuse system resources, gather information, and deliver malicious ads (pop-ups, coupons, banners, etc.)
Overview of the Microsoft Locked Your Computer Scam
The Microsoft Has Blocked The Computer error indicates that the Windows Firewall has detected suspicious activity and the system has supposedly been blocked due to this. To avoid further problems, users should immediately contact a phone number ("1-800-745-9386") Offered.
Then supposedly you will receive help in solving these problems. In fact, the "Microsoft Has Blocked The Computer" error is fake, a scam that has nothing to do with Microsoft. Cyber criminals pose as certified technicians and offer support for a fee (which is not required).
In addition, these people often request remote access to users' computers to install malware and/or change system settings. They then claim to "detect" additional problems and offer further help for an additional fee. Therefore, we recommend ignoring "Microsoft has locked your computer" and never trying to call the old phone number.
This error can be fixed by simply closing the web browser or rebooting the system. Some PUPs and malicious websites run unwanted processes (eg, cryptocurrency mining) in the background without users' consent. This abuse of system resources can result in a significant decrease in the overall performance of the computer. Another drawback is information tracking.
Most PUPs record various information from the user's system, which often includes personal data. The data is then sold to third parties (possibly cyber criminals).
Therefore, the presence of information tracking apps can lead to serious privacy issues. PUPs are also designed to display "malvertising" ads, which hide underlying website content (thus hindering the web browsing experience) and lead to malicious websites, and in some cases even run scripts that download/ they install malware.
Therefore, if you click on it, you risk further computer infections. We strongly recommend that you immediately uninstall all potentially unwanted programs.

As mentioned above, "Microsoft has locked your computer" shares many similarities with dozens of other errors. They all claim that the system is infected, missing files, or damaged in some other way. However, these false claims are just attempts to trick unsuspecting users into calling and paying for technical support that is not needed.
Potentially unwanted programs also have a lot in common. Most offer "useful features" (eg system optimization, antivirus, file format conversion, etc.); however, these programs often do not offer real added value for average users. PUPs are only designed to generate revenue for developers.
Instead of providing any of the promised features, they cause unwanted redirects, misuse system resources, collect information, and display ads, posing a threat to your privacy and Internet browsing safety.
How did the adware get installed on my computer?
In some cases, potentially unwanted programs have official download websites; however, most of them are distributed using the above advertisements together with a deceptive marketing method called "bundling" - stealth installation of third party programs together with regular (mostly free) software.
Due to ignorance and careless behavior, PUPs often infiltrate systems without permission. The developers do not correctly declare the installation of the PUP; they hide this information in various sections (for example, "Custom/Advanced" settings) of the download/installation processes.
Furthermore, many users click on various advertisements and speed up download/installation processes. By doing so, they expose your systems to the risk of various infections and compromise your privacy.
How do I avoid installing potentially unwanted applications?
The key to computer security is caution. To avoid PUP infiltration into the system, be very careful when downloading/installing software and browsing the Internet in general. Only download your software from official sources and preferably use a direct download link (third party download/installation tools often contain malicious applications).
Also, scan each step of the download/installation process to opt out of any additionally bundled programs. Keep in mind that malicious ads look legitimate but are identifiable, as they often lead to surveys, gambling, adult dating, and other dubious websites. If you find these ads, remove all suspicious applications and browser plug-ins immediately.
