Yes, there is McAfee SecurityCenter and is configured for excluding
fdb files. I'm not in the habit of making filesystem level copies of
the fdb file (I did it time ago but it became into trouble). I usually
run gbak every day at noon while users are connected to de server, but
never ever before had this corruption.

Every time I make a restore users are not allowed to connect to de DB.
