How to use ESET Security Ultimate Help pages

Online Help is divided into several chapters and sub-chapters. Press F1 in ESET Security Ultimate to view information about the currently opened window.

Online Help enables 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 that do not contain the 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 prevent confusion, the terminology used in this guide is based on the ESET Security Ultimate user interface. We also use a uniform set of symbols to highlight topics of specific interest or significance.
