i sorta kinda suck at this...pleeeeaseee help!!

Ok so I'm not new to android devices whatsoever. However, I've never dug very deep into any of the devices I'd had. This one has given me so many i was left with no choice but to go snooping around. I've looked into my files and the task manager and I'm so confused. There's things there entitled "cow race" and silly things like that. Wth? Do i need these things? My phone has had major glitches recently and I'd like to get rid of anything unnecessary WITHOUT a factory reset. Help?
