I'm going to go and get my spybot back and reinstall it, I have something called Defender pro. I haven't used yet. I bought it several months back.
Let me add one more site http://www.grc.com/ to check your firewall at... also besides a software firewall I alway recommend a hardware firewall router (Linksys or Dlink) on any alway on DSL or Cable modem Internet connection, they NAT the IP address to your computer to private IP address that will not pass over the Internet, bottom line the only public face you show (if any) to the internet is at the public IP, WAN side of you hardware firewall router (and change the default router password!)
Will that work on dial up?
No really needed on dialup
