Good day! I'm Raniel, a Microsoft user like you. I understand your frustration regarding this issue and I'll do my best to help.
First, kindly double-check if your machine doesn't have any pending security patches. Go to Start > Settings > Windows Update > Check for Updates.
Once done, I suggest that you also install the Microsoft Safety Scanner or Malwarebytes Free, then perform a scan to ensure that your machine is free from virus. Here are the links to download them:
Microsoft Safety Scanner: https://docs.microsoft.com/windows/security/thr...
Malwarebytes Free (select Free Download): https://www.malwarebytes.com/premium/
Moving forward, I suggest that you refer to this article on how to keep your computer secure: https://support.microsoft.com/en-us/windows/kee...
I hope this helps. Good luck!
