Palo Alto FW: filter help

Trying to write a filter on alerts

(( zone.src neq outside ) and ( name-of-threatid neq 'ZeroAccess.Gen Command and Control Traffic' ))

​

Instead of this being a classic AND, this is taking both individually. How do I fix this? Effectively Im trying to filter this alert if its sourced from the outside. I still care about it if its from the inside.
