MacBook Pro - Single app starts freezing, then spreads to all apps/entire system.

For the past two days my MBP has been freezing up on about once/hour, if not more often than that. It starts with a single program giving me the spinning beach ball. Other programs still remain responsive, but they don't function correctly. For example, the last time it happened, my text editor initially was giving me the beach ball. I could still, however, go back to Chrome and switch between open tabs. However, I couldn't open any new tabs or navigate to a new page. After a minute or so I then got the beach ball on Chrome, and then it was everywhere. The dock is unresponsive, the menu bar is unresponsive. My only option is to hold the power button down and restart.

So far I have run the Repair Disk utility, and it says the volume appears to be OK. I also ran 2 memory tests using a program called MemTest. Those results also came back with no problems. I also turned off automatic brightness, but the problem has persisted.

One thing I should mention is that a few hours before this first happened, I downloaded a program from the AppStore called Memory Clean. I never actually ran it to free up memory, because the computer froze shortly after installing it, and so I uninstalled it immediately after rebooting, just incase that was what was freezing up my computer. Since it has been removed the problem has still happened several times.

Any suggestions on what I could try?

Here is my EtreCheck dump:
