Is screencast-o-matic.exe a Virus or Malware?
The real screencast-o-matic.exe is NOT a virus. However, malware sometimes disguises itself using similar names to trick users.
How to Tell if screencast-o-matic.exe is Legitimate or Malware
- File Location: Must be in
C:\\Program Files\\Screencast-O-Matic\\Screencast-O-Matic.exe or C:\\Program Files (x86)\\Screencast-O-Matic\\Screencast-O-Matic.exe. Any screencast-o-matic.exe elsewhere is suspicious.
- Digital Signature: Right-click the file in File Explorer → Properties → Digital Signatures. Should show a valid signature from "Screencast-O-Matic" or an associated publisher.
- Resource Usage: During recording, expect CPU usage to spike (dependent on frame rate) and memory usage to rise; compare with typical ranges in Task Manager.
- Behavior: The process should run primarily during recording or app usage. Persistent background activity when the app is closed can indicate malware.
Red Flags: If screencast-o-matic.exe is located in unusual folders (like Temp, AppData\Local, or System32), runs when Screencast-O-Matic isn't open, has no digital signature, or uses excessive resources constantly, scan your system with antivirus software immediately. Beware of similarly-named files like "screencast-o-matic32.exe" or "screencastomatic.exe" from untrusted sources.
