Wireless connection shut down by Norton Internet Security?

My main computer (OS W2K) is connected to the internet by cable. My laptop
(OS Vista) and my brother´s desktop (OS W2K) are connected to the internet
by Belkin wireless, the transmitter sitting on top of my main computer.

Today my laptop started playing up, and I lost the connection for some
reason. Thinking the program had become disconfigured, I went to look at my
brother's setup. His computer seemed to be working fine but, when I opened
his profile, a Norton box appeared. I couldn't close it. It offered 4
options. The top one was in square brackets. This was the option that
couldn't be chosen. (Sorry, I can´t remember what it said.) The other 3
options were (I think) Home, Away, Office (?). I chose Home. The wireless
connection has not worked since, and I can't get that Norton box to offer me
the options again.

Any suggestions, anybody?

Thanks.

JK

 

Get rid of Norton would be my suggestion even if it is working
