The Abine plugin for Firefox is a winner.

Not only does it tell what evil lurks there, it also allows you to block it and also delete the nasty cookies.

Another plugin for Firefox is “Cookie Culller”.
It, too, identifies what’s lurking on your machine and has an option for permanently blocking subsequent attempts for a site to deposit the cookies, again.

For the further, deeper cleansing of a computer, the paid version of Malwarebytes is invaluable.

As far as general AV/security, I use Zone Alarm’s premium internet security suite.

Thanks, I am no techie. I use Avast, Microsoft SE, and Malwarebytes freebie. These were recommended by FReepers that seemed to be computer smart. I seem to have a clean machine as best that I can tell, I never see nor hear from Microsoft SE, but the Avast sets off an alarm from time to time when I hit some websites it doesnt like. I am always looking to learn more.

I like NoScript and Ghostery for Firefox as well. Set them up so that everything is blacklisted by default, and then only allow those you absolutely must to use the sites you want to use.
