How about using PC Decrapifier? That's what I used for my recently bought Dell laptop and everything works fine. Just be sure you know what you are removing!
Just to add a little more to Keiths good advice, if you're not sure how safe it is to remove something, you can come back on here for more help.
Certain types of application, in particular Antivirus software (I'll use Norton as an example as it's often shipped with new computers), must be removed with the correct Uninstall Tool and not via CCleaners uninstall feature, otherwise you may have issues, and at best leave a lot of it's stuff on your PC.
