Mac Pro running sluggish, EtreCheckPro advising me to do things I don't understand.

Please post the full report here. Use the “additional text” button below the message.

Start by uninstalling Antivirus Zap and CleanMyMac.

Third party apps that claim to protect, clean, manage, boost performance, etc. are not needed. They use system resources while providing no benefit. They also may cause problems.

Any Third Party Applications that will interfere with the normal operation of the OS, is an invitation for disaster.

Certain Applications maybe available on the Apple Apps Store - this only means the Developer is prepared to pay Apple a portion on each sale. What the Application may do to the computer is up to the User to check this out before purchase

Any of the below should be removed as per Developers Instructions

1 - Disk Cleaner

This will include CleanMyMac , aka “ BrickMyMac “
