It looks like someone installed a db managment tool that either deliberatly or accedently added tables to msdb. This is not a good idea.
Tools like this may use the sytem databases as a source, but I would recommend you avoid adding tables to the system databases. Create a seperate database for the application to use, then remove the offending tables.
