likely you have picked up something evil in your browsing travels...there are some very vicious trojans, viruses, worms, hijackers, etc etc out there. Norton does a good job, but 1 level of protection isnt enough anymore. I would suggest several things to start in addition to running a full Norton AntiVirus scan (and do look to see if its even been updating itself...)
Adaware - available free at
www.lavasoftusa.com Pestpatrol at
www.pestpatrol.com (I think)
and I believe there are several free online virus / trojan / worm detection programs that will do a pass through your system. When I get back to office I'll post the addys for them.
