Just as a note Multi, I did all the nuke from teh sky and clean format and what I believe was still happening to my accounts was that they were tracking the connection IP and using remote desktop protocals to get back onto the machine. What finally cleared me was to power down my cable modem for about 15 minutes and then it got a new IP when it restarted. This was the only thing that got me clear.
As a side note, my issue was that they kept changing the account password (one of the trial accounts that I had at the time) which I had not put an authenticator on due tothe account being about to expire.
