Always set your browser to ask before accepting cookies, and you will have the opportunity to deny them from sites you don't trust. Cookies from trusted sites generally are not harmful, and can be very helpful (Borders, for example, sets a cookie so it remembers the three closest stores near you when searching for a book to see if it is instock; other cookies contain site passwords or homepage information.)
Either running Ad-AwareSE or Spybot Search and Destroy will produce of list of harmful cookies that you can, and probably should, delete.
Whereof one cannot speak, thereof one should be silent.
