Most spyware is delivered via Active X controls, not cookies.
but you can stop them from even opening up on your computer all together, by blocking thier domain in you cookies program you see! if they can't get on your computer, they can't instal or manipulate programs on your computer!! This seems to be working for me so far!
I found a list of spyware, adware and scamware on this site:
http://www3.ca.com/securityadvisor/p...cking%20Cookie
it has a list of all these programs and there aliuses. I just browse my cookie edit list and my spyware remover program and also look them up on google for domain info. then I mark them as always block! just to many of them out there to block but I can stop the ones from the common sites (Ebay ***boat ect.) from comming back! I had a porblem were I would loose my browser after 30 minutes. then I would have to scan for viruses remove them and repair my explorer. Thus restarting my computer every 1/2 hour.
