Someone can hijack your computer and take it over as well as get your passwords if you're using any version of IE. Microsoft will have a fix soon, but I am not sure if it emant tomorrow or NEXT Wednesday. It said "Wednesday", butt hen it gave some quote mentioning the process taking 8 days. So I am unsure if it will take 8 days from now or already began 7 days ago.

It is suggested that you use firefox, safari, opera, chrome, etc.... until it is fixed.

By the way it also mentioned that IE is still the most used browser, which apparently some developers don't realize, as they seem to design everything for firefox.
