When running Sizzy's Windows installer, you might see the warning "Windows protected your PC" by Microsoft Defender SmartScreen, marking Sizzy as unrecognized/risky.
While Sizzy is perfectly safe to use—as evidenced by thousands of our clients running Windows—Microsoft Defender flags the installer due to a delay in obtaining a signed certificate from Microsoft.
That said, we understand your concern and have taken steps to ensure that the application is safe and trustworthy.
Until the time we obtain a certificate, you can check the VirusTotal analysis for Sizzy.
As you can see, Sizzy is recognized as safe by all security software including Avast, BitDefender, ESET, F-Secure, Kaspersky, Malwarebytes, and Symantec.
To bypass the Defender warning, run the installer and click the More info button.
Now, click on Run anyway and install the application as usual.
