Boy you are full of opinions, but I see no proof in your paranoia. Exactly how is Game Booster malware??? I want facts, links, references.

How's that? Free software comes at a price unless you're pretty careful. While Gamebooster itself indeed doesn't sound like it itself is nefarious, the suppliers of the software have some nefarous stuff piggy-backing along with it.
Now, beyond all of this when it comes to things like 3rd party 'performance enhancers' that operate on such general levels they've largely become redundant to what the OSes do themselves and so you'll often see those programs and their authors heading into sketchier waters to turn a profit (if they're profit oriented, FOSS and the like tend to be safer bets for sure). Its not so much that I'm paranoid just I increasingly see little point to bothering with such software when it doesn't really do much and if something like this booster thingy means the difference of playing games consistently vs the system barfing on you I'd say its only a band-aid over a much more gaping problem with the system.
