Ok so a couple months ago i bought FIOS from verizon and found out that i can connect 4 computers with an ethernet cable to it. So i got my old computer and my new computer and connected them both to the router through an ethernet cable.Then weeks later my new computer starts crashing and i was wondering, can a virus travel thought the old computer's ethernet cable through the router and into my new computer?(Both are Windows XP if that makes any diffrence)
Thank You
