Windows blocked an unrecognized app from running
Windows blocks apps from unknown publishers to protect you. If you trust the program, click Run anyway to allow it. If you do not recognize the app, click Do not run to block it.
Windows Defender SmartScreen blocks apps from unknown publishers. This protects you from malware disguised as legitimate programs. If the app is one you installed intentionally and trust (like a game or tool), you can allow it. If you do not recognize the app, blocking it is safer.

Skip, I just want a technicianCommon mistakes to avoid
- Allowing every app without thinking — SmartScreen warnings are for good reason
- Assuming a warning means the app is malware — it just means it is not well-known yet
- Blocking an app you actually need — if you trust it, allowing it is fine
Signs you need professional help
- If you allowed an app and your computer started acting strange. If you want to check whether an app is safe. If you cannot access a program you trust because of the warning.
