Bah, Firefox! I either use IE or Netscape depending on the website (for the record I prefer using ENWorld with NS because of the tabs). I see no reason to get any other browser. Spyware? I've had maybe 2 major problems with spyware in the last two years. But then I avoid bad sites like, oh I don't know, gambling sites, shady porn sites, pirated software sites, etc. that are the nesting ground for a vast majority of spyware crap in the first place. And I have all the security updates on the computer, and run spyware scans on a regular basis.
You know, I don't think the browser argument has anything to do with security or standards or any of that. Those are excuses. I think it's simply hate for Microsoft because it's a big business. Think about it. A few years back, NS was THE browser of choice for all the Microsoft haters. Now none of them even mention it, probably because I believe it's owned by AOL (another of the evil coporations!). They've all gone to worship at the altar of Firefox. According to the Gospel of Open Code (

), anyone who isn't running Firefox on a Linux box is playing the Internet version of Russian roulette.
The reason they are relatively safe has nothing to do with Microsoft's inferiority, IMO. It's because viruses, trojans, spyware, etc are primarily produced by two types of people:
First is the punk kid who's listened to too much bad socialist theory in school, and thinks he's engaging on some 21st century crusade by exploiting MS vulnerabilities. What he really IS doing though, is annoying the hell out of normal people who have to deal with this crap. The punk kids would NEVER consider trying to exploit vulnerabilities in his favored OS and browser because it's all open source and non-MS and so is therefore perfect anyway.
The second are Russian crime syndicates who don't want to crash computers out of infantile glee, but who want to steal your personal information and profit off it. They're targeting MS stuff because the vast majority of people use it. Why should they try to crack systems that a small percentage of people are using?
