If you are using IE on Windows, you might want to think about looking at an alternate browser for today (or heck, forever). Microsoft released a warning about IE and IIS yesterday, indicating that they have a security hole which could enable hackers to get at your personal information when visiting compromised web sites. I personally recommend Firefox (the latest Mozilla browser), it's pretty slick. There's also Opera, which I used to use a lot when I was using Windows more.

I know a few friends of mine who still use Windows have said this feels like the last straw for them. Firefox works well and with this they're about to give up on IE for good.
