Select Firewall profile - from the roll-down menu select one of the defined profiles (for a
detailed description of each profile and its recommended use please consult chapter
Firewall Profiles)
Enable Game mode - check this option to ensure that when running full-screen
applications (games, presentations, movies, etc.), the Firewall will not display dialogs
asking you whether you want to allow or block communication for unknown applications. In
case an unknown application tries to communicate over the network at that time, the
Firewall will allow or block the attempt automatically according to settings in the current
profile. Note: With the gaming mode on, all scheduled tasks (scans, updates) are
postponed till the application is closed.
Furthermore, in this basic settings section you can select from three alternative options
defining the current status of the Firewall component:
o Firewall enabled (by default) - select this option to allow communication to those
applications that are 'allowed' in the set of rules defined within the selected Firewall
profile.
o Firewall disabled - this option switches the Firewall off completely; all network traffic
is allowed but not checked!
o Emergency mode (block all Internet traffic) - select this option to block all traffic
on every single network port; the Firewall is still running but all network traffic is
stopped.
Please note: The software vendor has set up all AVG Internet Security 2012 components to give
optimum performance. Unless you have a real reason to do so, do not change the AVG
configuration. Any changes to settings should only be performed by an experienced user. If you
need to change the Firewall configuration, select the system menu item Tools/Firewall settings and
edit the Firewall configuration in the newly opened Firewall Settings dialog.
Control buttons
Regenerate configuration - press this button to overwrite the current Firewall configuration,
and to revert to the default configuration based on automatic detection.
Save changes - press this button to save and apply any changes made in this dialog.
Cancel - press this button to return to the default AVG main dialog (components overview).
6.5. Anti-Rootkit
Anti-Rootkit is a specialized tool detecting and effectively removing dangerous rootkits, i.e.
programs and technologies that can camouflage the presence of malicious software on your
computer. Anti-Rootkit is able to detect rootkits based on a predefined set of rules. Please note,
that all rootkits are detected (not just the infected ones). If Anti-Rootkit finds a rootkit, it does not
necessarily mean the rootkit is infected. Sometimes, rootkits are used as drivers or they are a part
of correct applications.
