Looking for a "Youtube Bot"

I'm looking for some sort of software that I could leave running in the background of my computer that would re-watch videos on youtube over and over, I'm trying to help out my friend who is starting a lets play series of several games. The concept of the program/bot seems simple enough right?, I mean someone has to know of a good working program that would boost the views on a video I select for it to watch.

Fyi.... posted this here because I didn't want to end collecting malware and viruses on my computer from fake stuff, so i figured I would ask a rather reliable source.

Any help is appreciated and thank you
