Microsoft has released a security update for Windows 7 (KB4474419) that adds support for signed binaries with SHA256 certificates. Since the previous SHA1 software publishing certificates was deprecated on April 15, 2021, eScan will switch to SHA256 certificates for code signing.
To learn more about KB4474419, read the Microsoft article: https://support.microsoft.com/help/4474419.
If you're running Windows 8 or later, no action is required because SHA256 code signing support is already installed on your system. Windows XP and Vista users are not impacted by this patch.
Being a security expert, eScan recommends you to install KB4474419 update on your computer.
