No. If you do ever suspect that malware may have been accidentally installed, then you can run MalwareBytes to scan the system, but there is no reason to run MalwareBytes beyond the single scan...in fact I would suggest uninstalling it afterwards (uninstall option is on one of the app's menus, definitely no need to run the real-time scanner as that will interfere with the normal operation of macOS as well).

macOS already has great built-in security especially when combined with the user practicing safe computing habits. Here is an excellent article written by a respected forum contributor which has some tips for safe computing habits:
