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.
