Without a modem or something hooked to the phone line to use, it would be more of a nuisance than anything. I'd still try and prevent these things from getting on my system, and removing them as quickly as possible if they did somehow find their way on. Some may have contingency plans in place for cable and DSL users.

As I use a Modem Router for my Internet and have no dial-up equipment on board, is there any need for me to run AntiDialer software. I know that some of the AntiSpyware packages that I run do look for Dialers but are Dialer of any danger to people who can't Dial Up?
