Unknown User's Shared Library On "Secure" Home Wireless Network

[Pukey]

Has anyone ever experienced this? I am on a secure wireless connection at home with a WEP pass code. The other day in iTunes on my PC I saw a Shared Library of someone I did not recognize. I'm concerned my "secure" wireless connection may have been hacked. Or is there any other less worrisome possibilities that this could be the result of? Any ideas/suggestions/advice/feedback would be greatly appreciated!
Thanks!

Switch to using a WPA pass - a WEP one can be hacked open in under 5 minutes.

This happened to me. I moved to MAC address filtering soon after.

Thanks guys! I think I'll switch to a WPA or a MAC address.
