You can purge all viruses by leveraging the Forefront Protection 2010 for Exchange Server (FPE) custom worm purge list (CustPrge.dat). Set the virus Action to Delete for each scan job type (transport, realtime, scheduled) for which you want to purge viruses. In the custom worm purge list, add a single asterisk (*) followed by a carriage return. For more information about purging all viruses by using the custom worm purge list, see “Creating a custom worm purge list” in Purging worm-infected messages.
