38 McAfee® VirusScan® software version 10.0
Updating VirusScan
When you are connected to the Internet, VirusScan automatically checks for
updates every four hours, then automatically downloads and installs weekly virus
definition updates without interrupting your work.
Virus definition files are approximately 100 KB and thus have minimal impact on
system performance during download.
If a product update or virus outbreak occurs, an alert appears. Once alerted, you
can then choose to update VirusScan to remove the threat of a virus outbreak.
Automatically checking for updates
McAfee SecurityCenter is automatically configured to check for updates for all of
your McAfee services every four hours when you are connected to the Internet,
then notify you with alerts and sounds. By default, SecurityCenter automatically
downloads and installs any available updates.
NOTE
In some cases, you will be prompted to restart your computer
to complete the update. Be sure to save all of your work and
close all applications before restarting.

connected to the Internet, you can also manually check for updates at any time.
