I use Netscape 4.80, Firefox and Mozilla, don't have firewall installed and no antivirus active and I never had any problem, but many times that someone uses IE6 I have to waste half an hour cleanning all the mess installed, typicaly gives with Adaware 60 to 150 unwanted entities and all thanks to IE. Want to live in peace?, don't use IE neither Outlook!

Stupidity also evolves!
