It happened this morning and then just now. I use alt+0xxx frequently for non-keyboard characters, for example alt +o176 = the degree sign. Today when I did that, ETO closes out, and I get to a Google screen. I wondered whether num lock wasn't on, but it was. Same thing also happened with the numbers above the keyboard.
I have seen older viruses mess up key maps , not like that ever, but is 0-9 working without the alt key?
some keyboards have a button dedicated to launching a home page
EDIT: win7 pro w.firefox = ok, ° // also this only works if you use the numeric keypad
Good news. Mine is still not working. Mind you, my laptop has no independent numeric pad and also it has a US keyboard which means I have to do three key presses to get some common characters, like £ for example. Meant to get a UK keyboard but too lazy/tight...£30UK.
