msuvdaa09, an overwhelming majority of those files need to be deleted. Proceed as below.


First: "MacKeeper" is notorious garbage that should never be installed on any Mac. You can see for yourself it did nothing to prevent the problematic "... will damage your computer" message. Your Mac will never run properly with it installed. Uninstall it according to its instructions. Rule 1 of Macs is don't install junk.


Then, start your Mac in "Safe Mode": How to use safe mode on your Mac - Apple Support. Starting in Safe Mode takes longer than usual so let it finish.


While in that mode, drag all the files in those folders to the Trash except those with the following in their names:


Canon

Google

Microsoft

Valvesoftware


When you are finished they are the only files that should remain in any of those folders.


Then, restart your Mac normally and confirm the alert messages cease to appear.
