ESET Server Security for Linux (ESSL) is distributed as a binary file (.bin).


Make sure that no other antivirus programs are installed on your computer. 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.
