Gcat, you said what I was about being smart, read the EULA and it should help.
For a cleaner for your system there are a number of them, I use 1click sweep from PC solutions, completely cleans your hard drive( when proper settings are used.
I worked for a number of years for "The Big Brother" in security, they go by 3 initials and found the sweeper to be one of the best.
Cravin, with spybot it records a lot of info from your system and sends it back to them, they say it helps them in detection ( it's in the EULA, not worded so most people can understand)
of course you can always use a program like I got, someone trys to hack my machines it gives them a real nasty program that eventually erases their hard drive ( a present from my old employer) they can get the info but lose it and more.
