After being an Internet Explorer user for many years, I finally gave up on that browser this summer after the almost daily articles detailing new security holes and threats. Exploits that, naturally, hackers and spammers jumped all over. The replacement? A nice little program called Firefox.
I cannot recommend this browser enough and wont bother listing all the benefits. All I'll say is it can do just about everything Explorer does, and much more. Hit the web site at getfirefox.com and read the features for yourself. They just released version 1.0PR and started a campaign called Spread Firefox aimed at getting 1 million downloads in 10 days. They hit the million mark.... in about 72 hours.
Both browsers can co-exist on your system peacefully, which makes it very easy to try Firefox or use both at the same time. With the way Microsoft's browser is so attached to the general operation of the Windows XP system (especially with the Windows Update service), it's not recommended that Explorer be completely uninstalled anyway.
On a side note, Internet Explorer has some new security enhancements..... if you download and install Windows XP Service Pack 2. It's ok, but Firefox is still better in my humble opinion. Especially considering some users have had trouble when installing SP2, along with the emergence of yet another flaw in that update. Ugh. You Mac and Linux users out there (stop laughing at us), Firefox is available for those systems as well. Take back the web.
