Macbook Pro is freezing for a few seconds, every 3-6 minutes and the CPU is low during the freezes. (Etrecheck report included)

Question

I've been trying to fix this for a few days now. I think it started the day after I hooked it up to mirror video to my TV, which I've done before with no issues. I've tried a few of the popular fixes like resetting the smc and pram, and I kind of feel like a tech genius right now for saying that, even though I don't really know what those things are
I also saw where people asking for help were asked to download a program and paste it's results, so I've done that. Here is the etrecheck report:

I've already gotten rid of a few third party apps, but maybe I should get rid of more? Anyway, I'm very frustrated and any help will be much appreciated. Thanks!

The problem with garbage software is that their uninstallation programs tend to be garbage as well. In the case of CleanMyMac, it is ineffective and leaves components behind. I verified that myself a few months ago and was curious if they had corrected it by now, but as of five days ago (my last test of it and similar junkware) it had not been addressed.
Only MacPaw, its developer, can know the reason its installer doesn't work, but I can think of two possibilities: either they are purposefully leaving those components behind for reasons known only to them, or they simply don't know what they're doing. Neither one of those possibilities is particularly comforting for the user.
Using CleanMyMac to remove what it considers "junk" will corrupt a system. I know of no way to recover from the effects of having used CleanMyMac than to completely erase the volume on which it was used, reinstall OS X and essential software from their original sources, and restore your essential work files and other documents from a backup that has not been corrupted by CleanMyMac or anything else.
This claim in particular is an outrageous one that cannot be justified under any circumstances:
The above screenshot was recorded on a brand new, previously erased Mavericks installation containing only one minimally configured User account. Just 500 MB can be removed "for free". Therefore there is no Mavericks - running Mac in existence that can be totally "cleaned" of what it considers "useless junk" without paying them for the privilege. Even if localization files (most of what it considers "useless") were to be removed, those files have exactly zero effect on a Mac's performance. On the other hand the lack of them will have effects only their respective developers can know.
MacKeeper on the other hand offers an effective uninstaller, but if you cannot find its app you may need to install MacKeeper again for the sole purpose of uninstalling it.
Once installed, follow these instructions:
Follow these instructions to uninstall MacKeeper. They have been tested with the most recent version of MacKeeper. Earlier versions than the one released in 2012 require more extensive work to uninstall all its components.
If you actually used MacKeeper to alter your system, e.g. "remove excess binaries" or such, you will need to reinstall OS X as well as all your additional software. Uninstalling MacKeeper is insufficient to reverse the corruption it is capable of - once again, that is if you used it.
If you merely installed MacKeeper but did not use it to perform any particular action, the following instructions will suffice.
If you used MacKeeper to encrypt any files or folders, use MacKeeper to un-encrypt them first.
Quit the MacKeeper app if it is running.
Open your Applications folder: Using the Finder's Go menu, select Applications.
Drag the MacKeeper icon from your Applications folder (not the Dock) to the Trash.
You will be asked to authenticate (twice):
You do not need to provide a reason for uninstalling it:
Just click the Uninstall MacKeeper button. You will be asked to authenticate again.
After it uninstalls you may empty the Trash and restart your Mac. All that will remain is an inert log file that does nothing but occupy space on your hard disk.
Uninstall Trusteer Rapport as well. Follow its instructions, which I believe are effective. Resorting to so - called "cleaners" and "zappers" is a bad idea that will only exacerbate your problems. At present, that Mac is a complete mess that cannot possibly operate as Apple designed it to operate.
