They show in the report. The uninstall didn't remove all of the program files. Did you try resetting the home folder permissions?

See if you can find the file(s) using one of these programs. If you go Finder/View/Show Path Bar, it will show you where it is located.

Clean My Mac is another piece of malware!!! Please uninstall it as well using the developers Uninstall instructions. Ad mentioned, Mac OS does not require or benefit from using any type of cleaning, antivirus or ANY other third party "maintenance" apps.

• First, locate the uninstall process from the developers of CMM and uninstall it!
• Next, re-install McAfee AV product
• Locate the developers instructions for uninstalling McAfee and uninstall
• Finally restart the computer in Safe Mode to clear some caches.

To be honest you have made a pretty good mess of your system. If after doing the above your system is still unstable, you will be forced to do an erase and install and start over.

Thought so, that is the root of the problem! Mac OS is EXTREMELY secure and it does not benefit by using any antivirus, cleaning or any other third party "maintenance" apps. If simply kept up-to-date and otherwise left alone Mac OS will remain stable and secure.

You indicated you uninstalled AVG, however did you use the developers uninstall instructions to do so? If so that is good, if you used another method you will need to re-install and then uninstall the per the developers instructions!

I located this youtube , please look it over and it should help out https://www.youtube.com/watch?v=0UfhaE3CMHM

Well it's your computer, keep them and have a buggy slow computer that has bloat ware that does nothing but cause problems or uninstall them per the developers instructions and have a stable, fast system. Your choice! These forums are full of users that have had similar situations and the recommendations are always the same.

I would not allow cleanmymac or AV software within 10 miles of any of my Macs.

Since the problem is not evident on your other user account, there is obviously a problem with yours. Most likely caused by the apps you have installed. Unless you uninstall, restart the computer, reinstall a fresh OS, and then test, there is no way to troubleshoot.

Antivirus apps: AVG, CleanMyMac

As suggested in the posts above, I would uninstall the above using the Developer's uninstall instructions. If you get the problem resolved, you can try reinstalling them later if you want to. I would also uninstall the Norton programs you have installed.

You may need to rebuild permissions on your user account. To do this,boot to your Recovery partition (holding down the Command and R keys while booting) and open Terminal from the Utilities menu. In Terminal, type:  ‘resetpassword’ (without the ’s), hit return, and select the admin user. You are not going to reset your password. Click on the icon for your Macs hard drive at the top. From the drop down below it select the user account which is having issues. At the bottom of the window, you'll see an area labeled Restore Home Directory Permissions and ACLs. Click the reset button there. The process takes a few minutes. When complete, restart.
