Joke-StressRelief" is neither a virus nor a trojan. It is a detection of the “program” type (under which non-malicious but sometimes unwanted objects are detected).
When run, this program displays a picture of some tools which the user can use to “destroy” their screen by clicking with the mouse pointer. No real damage is done to the system.
