Installing VirusScan Software
Determining when you must restart your computer
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 Table 2-1.
