From your start menu highlight spybot, a new box should open with a couple of choices, advanced mode and easy mode. Select easy mode, when it opens select search for updates. If there are updates download them. Now just click Check For Problems and wait while spybot searches your hard drives. This may take a while depending on the amount of files you have. Once the search is finished you can click on any problems it found and find out what they are and what they do. The ones with the checkmarks will be deleted so make sure they are not for programs you need or want. When you're done just click on >Fix selected problems< at the bottom and spybot will do the rest.
