It's part of the Norton Utilities package. What it does, is a one-button checkup of your system. It scans the registry for invalid entries and fixes them. It scans for invalid shortcuts and general application problems. There are other things it checks for too that I can't think of right now. It can't fix everything, but it can definitely help. The Norton Utilities package also includes Anti-Virus, and some other features that enable you to backup your programs. Basically, if you have a program that's working, back it up, and then if it starts crashing, you can restore from the backup and it'll usually work again. (If it doesn't it's because of Windows or another program.) The other advice I could give you is to minimize the number of applications running in your system tray, as these all consume memory and can cause problems. For example, both RealPlayer and Winamp put icons in your system tray for easy startup. Basically this means that some of the program resources are running all the time, just in case you open RealPlayer or Winamp. If you disable these icons you will see improved performance.
