google keystone agent is legitimate.

I think the rest are probably malware.

How does posting a screen shot of

~/Library/LaunchAgents

fix the problem --what am I missing to this logic?

Everything in that folder from after June 19 looks like adware to me.

Except cleanMyMac. That is junk. Its tragic flaw is that it also "cleans" vital parts of Mac OS X, often requiring a re-Install.

Thank you! The CleanMyMac was just a trial version so hopefully I'll be OK.

what's wrong with using malwarebytes?

The problem with using malwarebytes is mostly a philosophical problem, SO FAR. The tool itself is a fine tool, but some would say that using a downloaded tool that you deliberately download to fight things you accidentally downloaded is wrongheaded.

The idea is that if you download anything to fix this problem, malware will eventually be changed to attack the download, to the software, or both. The more popular the solution, the more likely it will be under attack from malware. So simply by using the download solution, you contribute to the failure of the download solution to work for others in the future.

Then when you need it most, downloading something will make your Mac worse rather than better.

Apple's article lists the places you should check, and what you should check for and delete. Using Apple's article makes you smarter about how your Mac works, and better able to defend yourself against future attacks.

You logic is valid but one cannot discount that the tool (malwarebytes) will be modified to address the changes that the 'enemy' makes. Per Thomas Reed, the originator of Malwarebytes, enhancements have already been incorporated in the product and I suspect that will continue. This is just part of the continuing war between the purveyors of malware and viruses and those who work to negate their malicious efforts.

Ciao.
