There is a big difference between IE and Firefox/Mozilla/Netscape. The structure of IE make it very easy to be attacked by virus, spies and hijacked by hackers, Microsoft and other companies and sites. Firefox/Netscape/Mozilla on the other side are autonomous, don't use the Windows structure/active X/Java for running, so is very diificult to be attacked and if you turn of Java (which cannot be done with IE) these browser become 100% inmune. I have a DSL conection, no firewall installed, use P2P, rarely use IE and haven't any active antivirus. Only run the antivirus once a month or use it to test a specific file that I have doubts about. I have no reports of virus for some years. Spies are very much common and are only installed if you use IE or install some comercial programs.

Stupidity also evolves!
