I ran your advice.
There is still the problem.
Well,
I put accessDUMP.exe file in the “Exclusions global” (“Eclusioni Globali”) with
C: \ Program | AccessDUMP \ *
and my file works now.
I hope this does not make the problems.
If you like(Avast) I have the possibility to sent you files
ACTION and DDL
of AccessDUMP as in ST6UNST.TXT
