If you almost never use Internet Explorer [use Mozilla/Firefox/Thunderbird] except for some Microsoft downloads, that only work with IE.
Is it necessary to keep downloading IE Security updates ??
In other words, is a IE vunerability "open" if IE is installed BUT not used ??
My primary Microsoft OS is Win98SE and I get "periodic" IE updates through Big Fix and frankly I'm not sure what "path" Big Fix uses for their downloads. So I don't know if I'm using IE for these downloads or not !!
I still install all of Big Fix's updates, but I wonder if it's really necessary.
