First of all thank you for all the help. I've had this computer for a couple of years, and it's still in pretty good condition. I want to clean up any unused and useless software I don't need. Also I want to make sure there is no spyware, or viruses affecting the efficiency of my system. I'm running a Windows 7 OS and it's an HP 2000 Notebook PC. My processor is an AMD E-450 APU with radeon HD graphics 1.65 GHz, and my system type is a 64 bit. What should I absolutely keep and delete? I want to know a lot more about computers and have no idea where to start. Please help!
