A one-time delay during a large scan is different from a repeatable freeze or crash. Record what the app was doing and the exact time before restarting it.
Try one clean restart
- Wait briefly to confirm that the window is not processing a large object.
- If Windows continues to show Not Responding, close the app once through Task Manager.
- Restart Windows, update Gridinsoft Anti-Malware, and repeat only the action that triggered the problem.
- Note whether the freeze occurs at startup, during Update, during a particular scan, or while reviewing results.
If it happens again
Open Tools → Application logs if the app remains accessible, save the entries around the incident, and collect system information. Send Support the incident time, app and Windows versions, action being performed, exact error, and relevant Application Log.
Do not add broad exclusions, change Windows compatibility settings, or disable security controls without evidence that one of them is involved in this specific crash.
