Might wish to take a look at this. For the time being I would probably recommend that everyone use something like Netscape, Mozilla, or Opera, if you have them available. the MyIE2 claims to have IE as a core, but it looks a lot like a Mozilla (open source) core with some IE skin trappings. However, if uncertain, probably better not to use it until IE is well and truly patched.
Steven,
I just downloaded Mozilla last night, and am looking at the usual stops for the first time today. So far I like it much more than IE.
