Safari won't quit

1. Have you removed Safari from System Preferences...>Users & Groups>Login Items?
2. How to force an app to quit on your Mac - Apple Support describes the (force quit) command.
3. Try a Safe Mode Start.
4. You won't be able to uninstall Safari.

Use these two User Tips to help you install/run/report your system configuration:

1. Etrecheck - the handy reporting tool for … - Apple Community
2. How to use the Add Text Feature When Post… - Apple Community

A quick review of your report indicates to me that:

Battery: Health = Replace Now - Cycle count = 1071

Antivirus software: TotalAV

Adware - Adware detected.

Unsigned files - There are unsigned software files installed that could be adware and should be reviewed.

Apple security disabled - Apple security software is disabled. This computer is at risk of malwareinfection.

~/Library/LaunchAgents/com.macpaw.CleanMyMac.volumeWatcher.plist

~/Library/Application Support/CleanMyMac/CleanMyMacHelperTool

1. Replace your battery.
2. I recommend that you delete TotalAV. It is useless.
3. Remove Adware using EtreCheck. You may also want to consider using MalwareBytes to remove the Adware.
4. I'm not really sure of what "Apple security disabled means. Perhaps someone else will chime in.
5. Delete CleanMyMac.
