As many teenagers do, I have been on a few dirty websites. After viewing these sites, I delete the history and temporary Internet files. For Christmas, I am getting an HP laptop, and I'm giving my mom my computer that I have now. My aunt suggested to her that she gets someone to clean out all of the stuff on the computer. I'm afraid that this computer person will be able to tell her if I have been on dirty sites and such. Are people able to do this? If so, how can I cover up my tracks?
