Have you scanned for malware and viruses? If so, what tools did you use to scan your system?

I did. It's Windows Defender

Download and run Malwarebytes. Remove all threats identified.

https/www.malwarebytes.com/mwb-download/

I use the free version. You can use the Premium trial version as well.
