You can have the anti-virus running on that system. But make sure that
it doesn't scan the database files, otherwise the performance will
diminish up to 50% speed penalty and it was also relative to the size
of the database file. There are good chances that the virus scanner
will read the whole file on every access, while FB doesn't, now
imagine that impact on a 100MB database file. To really prove this,
try it yourself and look at the difference in performance, but make
sure you have a good size database, since a small database will
probably hardly have a difference in performance.

See my note above.

Are you having problems? The only performance problem is related to
Win2003 disk shadowing, simply deactivate it.
