read my original post:
since 9:49 eastern time, someone at ip address 12.239.146.24 has been pinging/hacking my computer. It is now 1:03 pm eastern time. I am getting a notice from my firewall about every 4 minutes with this ip, and it says it comes from Gnutella. I just joined Gnutella a few minutes ago so that maybe I could receive some help on this...I already notified attbi. I was quite surprised to see Gnutella show up on my firewall log today, and it has been constant ever since.

I installed nothing...just signed in so that I could join the forum..that's it..created a user name and a password
