hmpalert.dll is a critical Dynamic Link Library file for Sophos Intercept X
and HitmanPro.Alert, designed to protect systems by monitoring and blocking
exploit techniques. It operates by injecting itself into running processes.
It is often associated with system crashes (BSOD), application errors, or
performance issues
