If 'Treat files as OK' is selected, files will be moved to the destination directory. If 'Refuse upload, try again' is selected, the user will be prompted to try again later. If 'Treat files like viruses' is selected, files will be moved into the quarantine area, or deleted. Warning: With this option, if for some reason clam fails to run (usually because of an invalid pathtoclam), then ALL uploaded files will be moved to the given quarantine area, or deleted.
