DSL is only as secure as the coputer that is using it. other than that...

IIRC yahoo DSL is provided by AOL and they are just using the yahoo name. 'nough said.

on a side note, I wouldnt trust the software firewall that come with most dsl subscriptions, unless they are just sending you a copy of a known companies product becasue chances are is full of their biased crap, or not up to par becasue it is not their primary concern.
