Hi. I'm David, and I'm happy to help you.
I usually see this behavior occurring due to malware actions.
I suggest you do a full scan using Microsoft Safety Scanner. Download from the link below.

Also, do a full scan using Malwarebytes as a second opinion.
Download through this link: https://malwarebytes.com/
IMPORTANT: When installing, a 14-day trial will be activated. I suggest disabling this trial to avoid conflict with your current antivirus. Access the Malwarebytes settings (gear icon at the top of the window), tab "Account" and click "Disable".
After scanning, you can uninstall it.
Feel free to ask back any questions.
