I'm on the 780 at present.
I had just run a normal scan and afterwards it suggested
a boot scan and also suggested I download paramets for
a more accurate scan.
I didn't download anything but I did select a boot scan
(which is running at present )as a good way of checking out
the system before we backup the HD.

SInce I'm on the 780 it also noticed it has the same exact
problem as the 8500 where the backspace key doesn't function.
Now thats odd,... so we have to do both computers.

Also could you give me a reliable link to download the Microsoft
4000 ergonomic keyboard manual? I searched for it but there' so
many I'm afraid of downloading some malware with my past history.
Thoughts/suggestions,.?
