There are several methods for installing ESET Internet Security on your computer. Installation methods may vary depending on country and means of distribution:

Live installer can be downloaded from the ESET website. The installation package is universal for all languages (choose a desired language). Live installer itself is a small file; additional files required to install ESET Internet Security will be downloaded automatically.

Offline installation – This type of installation is used when installing from a product CD/DVD. It uses an .exe file that is larger than the Live installer file and does not require an internet connection or additional files for the completion of installation.


Make sure that no other antivirus programs are installed on your computer before you install  ESET Internet Security. If two or more antivirus solutions are installed on a single computer, they may conflict with each other. We recommend that you uninstall any other antivirus programs on your system. See our ESET Knowledgebase article for a list of uninstaller tools for common antivirus software (available in English and several other languages).
