It obviously sounds like a viral scam.
DO NOT WANT.
Are you stupid or what?
I used to use this when Minecraft had some bad framerate problems. All this does is turn off some processes that you aren't really using or need at the time, it all depends on your computer though if it will make a difference. Some people do this, but this program turns off processes for you, so you don't mess any thing up; like turning off
explorer.exe. Afterwards you can just turn Gamebooster off and it will turn the disable processes back on.
