Where do I find this? I searched for Bitdefender and didn't find it.
Bitdefender is a third party anti-virus app which @alexanon has installed on their computer....that user made it seem it would fix everyone else's issue, not realizing that most people are not running Bitdefender.
However, their advice isn't totally useless since other anti-virus apps, cleaning/optimizer apps, or third party security utilities could be causing a similar issue. None of these types of apps are needed on a Mac and will usually cause more problems than they solve. If you have any of these types of apps installed, you should uninstall them by following the developer's instructions....of course it is your computer so the choice is yours whether to run junk apps. macOS already has great built in security especially when the user also practices safe computing habits as outlined in this excellent article written by a respected forum contributor:
