I have a couple of spread sheets from FPGA vendors for power
calculation. They "protect" the spread sheet, I assume so that you
don't mess with the calculations. I find that my anti-virus software
can't open the document and reports an error every time it is scanned.
I tried to disable the protection, but that option is not available on
these files. Anyone know what is going on? Even if I need a password
to unprotect the workbook, I can't find where to enter it.

I guess I can just delete it to get it off the PC and download it fresh
each time I need to use it, or maybe put it on a CD. But I am tired of
going through a list of dozens of errors on protected files each time I
run my AVS and I am getting rid of them one way or the other.
