Do you run ESET on Windows Vista or Windows 7?

What is SHA-1?

SHA-1 is a digest algorithm of the code signing certificate used by ESET to sign the code of its products. In a short timespan, ESET’s SHA-1 code signing certificate is expiring. Microsoft announced deprecation of Secure Hash Algorithm 1 (SHA-1) and started migration process to SHA-2 in early 2019. Newer ESET products use SHA-2 certificates meeting security standards.

ESET will no longer work on Windows Vista and Windows 7 without Microsoft updates

Your ESET product will no longer update its modules, including the detection engine, on operating systems without SHA-2 support. Ultimately, your ESET product will not be fully functional and will be unable to provide sufficient protection.

•Which version of Windows operating system am I running?

Some ESET product versions expired on January 27, 2020. The rest will expire by April 15, 2021.

There is a fix, but not for long

To continue receiving protection and the latest ESET features,

•Windows 7 operating system users must install SP1 and apply the appropriate Microsoft Windows updates,

•Windows Vista no longer supports SHA-2 and the latest ESET products do not work on this operating system.
