Text in mail replaced by question marks in boxes

I recently just opened my mail again and out of nowhere the text in all mails is replaced by question marks in squares. the preview on the left of the mail is normal text only if you open the mail the text is changed.

This also happens in internet pop-ups when I want to connect to a public WiFi.

I got no third party font manager and opened Font Book but I can't see ANY fonts in it. I scanned my MacBook with Bitdefender but don't have any virus.

There are no known Windows-like Viruses in the wild that self replicate and affect macOS, because of the underling UNIX Foundation and Permission Limitation.

The The Built in Security is all that is required to protect the computer.

Read up on the first 581 posting regarding BitDefender and decide what to do with this Application.

Should “ Certain & Specific Software “ referenced from above be installed - it will negatively impact macOS. It is suggested, to download directly from a respected ASC Contributor, the application Malwarebytes for Mac.

It is free or paid for added features.

Run the Application and it should remove the malware / adware. Once done, restart computer and test.
