Explorer 6.0 = Internet Explorer 6.0?
I don't think you can uninstall IE at all. It is deeply mired into windows itself. How about installing a different browser and setting it to be the standard for opening websites?
My windows is fucked up because of some Vundo trojan and McAfee blocks all attempts it mades to display ads - I've never ever seen a single one.
However the popup of the virus scanner is annoying - but that could be turned off I guess. Nevertheless, I see no way to get rid of Internet Explorer under windows - sorry.
How about migrating to Linux? Download a one CD life system of Ubuntu to test it and if you like it, overwrite windos.
