When a message containing virus is received you get a warning a a couple of choices (including deleting the attachment from the message).
But, if you want to set up automatic handling of this you only have the choises "Silent mode: Yes or No". And under Heuristic "Let be delivered, Delete/Deny access, Mark in subject filed". Which of these options does the same (that is only deletes the infected attachment - not rest of message).
In the help file they talk about an extra "tab" with options on what to do, but I can't find that in the program (the help files doesn't reflect the tabs I really have in the options).
