I hit it and saw it was linking both computers. I have no idea what program (ie: tunes) or if it was network. I was on the gateway computer a long time ago and it asked me if I want to sync my computers.
I'll do the best I can: When I run malwarbytes? on the dell computer? It can't scan certain files that are under the 'randomname' (fake for privacy reasons) which is the adminstrator name of the gateway computer.
