Exactly and I never ever had any problems with my IE either... we all have to agree that all those stories are a little bit blown out of proportions by many IE antagonists out there. Right now I'm watching the Firefox vs. Opera fight... when Opera came out as a wonderful free product, everything started to go down for Firefox. Now they got another enemy to fight against...
I don't even know what's spyware/adware anymore and everybody who uses SpywareBlaster will say exactly the same... So if you know how, you can be "clean" even with IE, and you don't need any other browser, especially not all those add-ons that will just make your browser crawl...
EDIT: Of course some people like to have more useful features in their browser, so it's understandable that they always look for something different. Both Firefox and Opera are pretty much fully loaded, so I guess they are good choice for people who really need all those additional bells and whistles. What I don't like, is usually those competitive browser developing teams towards IE, tend to search for IE's vulnerabilities just to prove how invulnerable their product is... they do that so often, so they sometimes just forget to clean the mess in their own backyard...
Maybe they all should unite and work together to help people, instead of fighting and trying to prove how really bad is other competitive product... I am sure we all would surf much safer then..
