Short bio

Joketool. is Malwarebytes’ detection name for a category of riskware that causes users to panic by making the affected system appear that something is wrong, such as simultaneously displaying many message boxes on the desktop or controlling the user’s mouse cursor.

Type and source of infection

JokeTool detections are usually harmless programs disguised as legitimate threats. Such files are meant as a joke and appear to perform undesired tasks, such as deleting files, formatting hard drives, or anything that could cause alarm.

Some antivirus program detects them as threats as they can sometimes interfere with the normal operation of the computer. They can also cause inadvertent damage if, for example, a user panics and shuts down his pc by pulling the plug to prevent a perceived file deletion but actually damages his PC in the process.
