modem command

i have got this problem,whenever i connect to the internet with a adsl modem my dial up modem tries to dial up somewhere,but it can`t cause i unplugged the in phone line and what happens is that it uses all my cpu power for about 3 minutes till it gives up,i can`t find any virus or worm or trjon,but i think it may be some program trying to connect out to it`s home company,but as everything is frozen i can`t check up what does this,with the old harware modem at lest on some of them we could get the last few number it dialed and i wonder if you can do this and if yes what the command is as i plain forgot,sure hope someone can help me out,cause the only other way will be to format and redo which i don`t like doing that much.thanks to anyone who will try to help out

Well, the obvious first. Have you checked your connection settings in ie to see that the appropriate connection is set as the default?

Don't recall the modem command, but you might want to read here http://forums.windrivers.com/showthread.php?t=57348 for detecting removing spyware. Suggest you run spybot and if the problem remains post the hijackthis report.
