Also with Dial-Up problems.. you may want to get Lavasoft's Ad-Aware 6 build 181 Spyware detection / elimination software... sounds like your system went to a site that used an active x control that installed a hidden dialer on your system that is force connecting...
Ad-Aware 6 will detect about 99% of those type of programs and eliminate them....
also Spybot Search and Destroy will eliminate those thigs as well
and finally a program called HackThis will scan for invalid entries and start-up programs that you can select independantly and have hackThis remove them or fix them.. works very well for IE 6 problems, especially in the registry settings...
also a good registry cleaner would be good after running 1 or all of these 3 programs to clean up things that are not detected.. I recommend RegScrub and Registry Cleaner...
all of these used 1 day a week will keep your machine clean of spyware and dialer programs and keep your IE working correctly.
hope that this helps...
