The goal, of course, is to make you call the number that’s displayed on the screen or convince you to purchase a dedicated program that can further protect your identity, data, and online profile.

Well, as already outlined, this is a scam, a deceptive alert that’s not related to Microsoft or any other OEM.

The message is usually accompanied by a red screen that disables the web browser UI.

So, you might think that everything was indeed blocked and that your computer and your info are at risk.

When you receive this fake red screen, it’s important to stay calm. Don’t download anything and don’t follow the instructions listed on that page. Most likely, your computer is not infected.

Afterward, restart the web browser app and if everything works normally, you are safe.

Even after successfully closing the web browser, you still have to scan your Windows 10 system in order to be 100% sure that you haven’t got any malicious codes from that fake red screen page.

The best way to do this is by running an in-depth antivirus scan:

  1. Enter your computer into safe mode – in safe mode, all third-party apps and processes are disabled by default.
  2. For reaching safe mode: press the Win+R keyboard hotkeys and in the Run box enter msconfig; then from System Configuration switch to Boot tab and under Boot options check Safe Boot. When done, save your changes and reboot your computer.boot options bios problems
  3. Now, once Safe mode is reached you can run a dedicated scan by running your favorite antivirus program. We recommend you to use specific software and not the built-in Windows Defender platform.
  4. If the antivirus system finds any infected files, make sure you remove them from your computer.
  5. In the end, reboot your computer into Windows mode.

3. Install and run an additional antimalware program

We also recommend you to install and run an antimalware program.

You should do so even after applying the previous section of this guide as sometimes regular antivirus programs cannot detect certain malware packages.

So, in that respect you can choose to use Malwarebytes.

Once more, choose to perform a full system scan in order to make sure that everything is safe and secured.

The Your computer has been blocked red screen alert isn’t displayed by Microsoft.

This is a scam, a fake notification that tries to trick you into buying certain programs or into downloading malicious files.

Thus, for avoiding such unpleasant situations, you should always use a dedicated security solution.

You can rely on Windows Defender, but if you want a more complex antivirus tool, then we recommend you to install a third-party antivirus solution that includes online protection features.

Also, navigate only to webpages that you can trust and don’t download any files that look suspicious.
