Do you think Mylot put a Tracking Cookie in your Personal Computer

No need. There's more market info in our profiles than you can get out of tracking cookies. They're pretty useless, anyway. I find data miners and other nuisances regularly, put there by people who honestly think that you can get meaningful data out of the erratic movements people make on computers. My computer guy found 800+ of the commercial data things on my old computer, when I didn't have any software to look for it. If you've got any anti-spy stuff you can check it out, and get rid of things like that. Symptoms are slowed-down computers, usually.
