Unknown Device...? WHAT!?

So I turned my computer on and something popped up and said "Found new hardware Unknown Device" WHAT?! What does that mean? I haven't installed any new hardware... i'm a little freaked out, can someone help me out please.
Also theres something in my firewall I don't understand i'll post some screenshots.

 

You know the drill.

Give computer and OS specs.

 

lol oops I always seem to forget to add that in.

Windows XP Professional Edtion...

and thats all I know

oh and my computers a Compaq

 

Hmm, interesting. You re-installed AOL recently? I've seen this sort of thing when installing AOL 9.0 on peoples machines, but the guy I did it with didnt have ZA do I've not seen that.

AOL use sorta virtual modems to make connections (WANMiniport is what its usually labeled with) I really don't know why, but that might be detected as a new device if you've recently installed AOL again.

 

Nope I haven't done anything to AOL. I haven't un-installed it, or re-installed it.

 

Should I not worry about it? Or...? Am I overreacting?
