How to resolve incompatibility issues with your operating system


Because both ESET’s SHA1 and SHA256 code signing certificates are expiring in a short timespan, ESET has obtained replacement certificates to sign binaries of its Windows products. However, some versions of ESET products released before October 2017 were not ready for a certificate switch. Therefore, users of those products will need to perform an upgrade to a later product version that supports such certificate replacement.

This change means that some versions of ESET security solution will no longer be able to update modules after January 27, 2020, including the detection engine, so your product will not be fully functional.

What are the different ESET product update and release types?
