Help pages

Welcome to the ESET NOD32 Antivirus user guide. The information provided here will familiarize you with your product and help you make your computer more secure.

Getting started

Before using ESET NOD32 Antivirus, we recommend that you familiarize yourself with the various types of detections and remote attacks you might encounter when using your computer.

How to use ESET NOD32 Antivirus Help pages

Help topics are divided into several chapters and sub-chapters. Press F1 to view information about the window you are currently in.

The program allows you to search for a help topic by keyword(s), or search content by typing words or phrases. The difference between these two methods is that a keyword may be logically related to help pages which do not contain that particular keyword in the text. Searching by words and phrases will search the content of all pages and display only those containing the searched word or phrase in the actual text.

For consistency and to help prevent confusion, terminology used in this guide is based on the ESET NOD32 Antivirus parameter names. We also use a uniform set of symbols to highlight topics of particular interest or significance.
