I have a free version of CC Cleaner which erases all tracking cookies and temp files whenever I schedule it (usually once per week) or run it by choice (when I get a message from Norton that I'm being invaded). It keeps my laptop functioning quickly and gets rid of intruders. There is also a pay upgrade, but I did not buy that. Wish I could give you better details, but HP helped me get this when I purchased the computer. Maybe you could do a search.
