Migration from OS 10.9.5 to 11.3.1 with Avast 13.12 FAIL

Hi,

Migrating to my new mac has caused Avast to fail. I get an internal error when trying to launch. I can’t delete it to upgrade to a newer version. When I try to place it in the trash it automatically reappears. I can’t launch it to remove the program either. Suggestions?

Thank you.
