As Others have mentioned regarding AntiVirus Software as source of the issue - Add to that Ad Guard is know to do about the same for e-mail contest issues

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

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.

Awesome, thank you! this problem was driving me nuts. Appreciate it - worked after uninstalling Avast.

Same issue here... started happening after I upgraded to Monterey. No issue on my other device which is still running on Big Sur.
