First of all, you should remove the windows script host file on your machine. This iliminates the possibility of a worm virus comming through your e-mail. On windows 2000 go to my computer, tools, folder options, file types, and remove the file called vbs - vbscript script file. Unless you are using visual basic in programming, then you can't remove this file or vb will not work. As far as antivirus programs go, In my experience Norton makes things hang! don't know why, you could try macafee or go with a really good Hardware Firewall such as the Linksys Router. Configured correctly, you should be invisable on the Internet.
