I am the one who requested the help on firewalls. I have been using, as indicated, NortonAntivirsus 2002. Everyday as soon as I connected to the web I would check for an undate. So I was always up to speed there. Norton 2005 was installed yesterday. This morning as soon as I connected to web I received a message from Norton that an attempt to invade with a worm was detected and stopped. So, evidently I was a bit behind in security with Norton 2002 even with constant updates. Thought I would let everyone know. Thanks again for help. I have disabled Windows firewall and going with Norton firewall. Sue S.
