Sounds like your laptop is a mess! If you treat your iPad the same way, it'll have a smeared cracked screen in a couple months, and maybe stop working completely! And, BTW, I've always been able to find decent bargain laptops, and they come with the keyboard included! Lock down your laptop, and if others share it, only give them non-administrative user accounts, and your malware and extra icons should be come a non-issue. Remember, your are the techie (since you are reading this), and you are in charge!
