If the problem comes back, PM me with details of the windows that open including the name on the dial-up window. There are a few nasty variants of malware/spyware circulating that the usual Ad-Aware/Spybot programs will not eliminate. My computer is quite highly security-rigged (being systems manager for my organization on top of my "daytime" activities) but I still got a stubborn one that had to be painstakingly removed "by hand"!
