Hello Phil,
When you run NAVC /helperror, you are telling NAVC to display all of
the possible DOS level error codes that NAVC uses. This is similar to
running NAVC /? or NAVC /help.
This is not the same as running a virus scan with NAVC. Nor are there
any viruses that are capable of infecting CMOS. The AntiCMOS virus is
a boot record/MBR infector only. It may attempt to change some of
your CMOS settings, but these can always be reversed.
To run a complete scan with NAVC, the correct command is:
NAVC /doallfiles /repair
I suspect that the problem you are running into is hardware-related.
However, you are welcome to send in a sample to the SARC virus lab in
the chance that there is a virus on the system that NAV isn't finding.
To submit a sample, please use the instructions on our web site,

Should you have any further questions, please don't hesitate to ask.
