Sounds like a P*rn site dialer. A very common way for adduult webmasters to make a dishonest buck. Tempted with "click here to watch the movie" users are duped into downloading very aggressive .exe files. These in turn cause your machine to dial an offshore # for dial up access. Because the charges are offshore it makes it nearly impossible to have them reversed. It works like an affiliate program, the dishonest webmasters are paid $0.50 - $1.50 / minute for every minute they get some unsuspecting surfer to be charged by the offshore company. The .exe file will place itself all over your machine, desktop, program files, automatically add itself to your "internet connection" list, etc...... You must search the whole machine for the "name" of the dialer program and remove it, as it tends to hide itself everywhere.
I am sure that this can be rigged to other than p*rn sites. Like a dialer from an offshore internet access site. In other words, you don't necessarily have to be surfing aaadduult site to pick one of these up. Imagine being connected all day to your business related surfing for $10.00 / minute, without knowing.
Below is an excerpt from a dialer site.
