Identifying and uninstalling or removing any rogue applications claiming to be legitimate security software is the first step in dealing with fake security warnings. These applications often masquerade as security software to trick users into further infecting their systems or paying for unnecessary services. Running anti-malware scans can be done after ensuring that no rogue software is manipulating the system. Not all legitimate applications need to be updated immediately in this scenario, especially not before dealing with the fake warnings. While contacting a professional is an option, it does not represent the best first action that an IT professional capable of handling this situation would take.
