File this under "there's never a right way to do a wrong thing". In fairness, Sybari is proactively alerting their customers about this bug, and they still make a darn good AV product. However, if they had resisted the temptation to make their product do something that shouldn't be done, they wouldn't have this problem now!

Hello reader,

What build of Antigen are you running? There is a known issue with
corruption of the priv1.stm associated with use of the Disclaimer.
Several clients have seen this, and it is easily resolved by turning the
Disclaimer off. However, this is only a work-around, and, as of now, future
releases of Antigen will not have a resolution to this, since we don't know what
the cause is. We have been unable to reproduce this in house, and we need
someone who is seeing this to run a diagnostic utility that will provide
more information and, hopefully, a solution.
