As of April 11, 2017 Microsoft Vista customers stopped receiving security updates, hotfixes etc. from Microsoft. If you are using an ESET product on a computer with Microsoft Vista, Microsoft will begin to enforce their End-Of-Life policy for Vista. Your ESET product will no longer be able to update the Detection engine or any product modules. In order to stay protected, you will need to upgrade your computer's operating system to a more recent version.
