your Clam folder if your on 14 should contain the following items.
-bin
-bin64
-ClamSup
-etc
-Log
-tmp
If it does not I would attempt a reinstall, if you don't want to uninstall or restart your currently running SmarterMail you could install somewhere else and pull the Clam folder from it's service directory and transplant them into your current SmarterMail. If this is still causing you issues I would create a ticket.
