If you pull the trigger- and it goes bang more than once before you pull the trigger again, yes, it is malfunctioning.
IF it is doing that, a good first step is to field strip it and clean it good. .22 LR is filthy stuff, and getting a firing pin gunked up can do strange things.
Semi-automatic means pull trigger, goes bang once. Pull trigger again, goes bang again.
Full auto- pull trigger, goes bang bang bang bang until you release trigger.
Your rifle should NOT do that.
