I had to redo the old pc myself when this one first got infected a month or so ago. I wanted some information from it, so I partitioned it and re-loaded XP in a separate area.
The internet we have is Verizon's fiber optic network, they call it Fios. The last time I looked at the router, PPoe or whatever it is was enabled. But this does not use a phone line at all. Once we switched from Verizon dsl to fiber optic, I had the phone turned off and we have had VOIP for a year or so. Hope you are having a nice Easter, and enjoy the rest of your day!
