Do you have a fully updated anti-virus? Have you run a full scan to attempt to remove the dialer? Try also running Spybot and Ad-aware and see if they can remove it, if your anti-virus can't. Other anti-spyware scanners would be good to try too, like Microsoft anti-spyware. Some other good scanners are A Squared (A²) and Ewido, that may successfully find and remove the dialer. If you have already tried that, you could try running Hijackthis, and post the results at a website that will interpret them and help you, like http://www.spywareinfoforum.com or http://www.dslreports.com/forum/security Good luck.
