Upgrading to a more recent version

New versions of ESET Internet Security are issued to implement improvements or fix issues that cannot be resolved by automatic updates to program modules. Upgrading to a more recent version can be accomplished in several ways:

1.Automatically, by means of a program update.
Since the program upgrade is distributed to all users and may have an impact on certain system configurations, it is issued after a long testing period to ensure functionality with all possible system configurations. If you need to upgrade to a newer version immediately after its release, use one of the methods below.
Make sure that you have enabled Application update in Advanced setup (F5) > Update.

2.Manually, in the main program window by clicking Check for updates in the Update section.

3.Manually, by downloading and installing a more recent version over the previous one.
