McAfee virusscan 4.5 Guia Do Utilizador

Administrator’s Guide

In many circumstances, you can install and use this VirusScan release 
immediately, without needing to restart your computer. In some cases, 
however, the Microsoft Installer (MSI) will need to replace or initialize certain 
files, or previous McAfee product installations might require you to remove 
files in order for VirusScan software to run correctly. These requirements can 
also vary for each supported Windows platform.

In these cases, you will need to restart your system during the installation—
usually to install MSI files—or after the installation itself.

To learn when you must restart your computer, see
