AOL WAN miniport installed by Dell...why can't I delete it w/o interfering w/other Internet connections? I don't use AOL.

I dont do AOL & continually find myself deleting Thier crap
Ken Peterson
It suddenly showed up and started installing itself as a wireless connection that I cannot disconnect. Seems to happen everytime certain individuals send pictures or .doc files. I now have 3 added "dial up" connections but no dial up. I'm thinking it is spyware. Shows up in Network Connections as WAN MINIPORT (ATW) with NO PASSWORD OR ENCRYPTION REQUIRED in the properties (further information...)
