Methods, program products, services and devices are provided for protecting a protected avatar from actions of a second avatar within a virtual universe. Protection is implemented for a protected avatar from a second avatar within a virtual universe, including identifying an activity of the second avatar and disqualifying the second avatar from engaging in the identified activity within the virtual universe as a function of a relation of the identified activity to the protected avatar. A protective action is defined, associated with the identified activity and executable against the protected avatar or the second avatar. Activity of the protected avatar or the second avatar is monitored within the virtual universe for an occurrence of the identified activity, and the protective action is executed against the protected avatar or the second avatar in response to detecting the occurrence of the identified activity.
