My first response would be to ask the FPGA vendor. Explain your problem and see
what they suggest. It's in their interest to make this as easy as possible for
you, and I've always found them helpful.

Alternatively, you can probably convince your AV software to ignore files you
place in certain subdirectories or some such. It depends on whose AV software
you use.

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.
