Seeing a SmartScreen warning? Here's why.
Windows shows “Windows protected your PC” for software that hasn't built up download reputation yet. It's normal for new apps from independent developers — and it isn't a virus detection.
Windows protected your PC
Microsoft Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.
App: UniClean_1.0.0_x64-setup.exe
Publisher: Unknown publisher

Reputation, not detection
SmartScreen asks “have many people run this file?” — not “is it malicious?”. New releases always start with zero reputation.
Still scanned
Microsoft Defender scans the file regardless. UniClean’s installer shows 0/67 antivirus detections on VirusTotal.
Check the file
Version 1.0 is not code-signed yet, so Windows says “Unknown publisher”. Download only from unisoftware.app and check the SHA-256 hash.
How to run UniClean safely
- Make sure you downloaded the installer from unisoftware.app.
- When the blue SmartScreen dialog appears, click More info.
- Windows will show Unknown publisher — version 1.0 is not code-signed yet. To be sure the file is genuine, compare its SHA-256 with the hash on our VirusTotal page.
- Click Run anyway to start the installer (or the portable build).
SmartScreen FAQ
No. SmartScreen warns about files that have not yet been downloaded by many people. It is a reputation check, not a malware detection.
Yes. As more people download and run UniClean, its reputation with Microsoft builds and the prompt disappears for everyone.
For UniClean downloaded from unisoftware.app, yes. Until our code-signing certificate is in place Windows shows “Unknown publisher”, so check the file came from the official site and its SHA-256 matches the hash on our VirusTotal page.
