CHAPTER 1 7
Introduction
Real-time Scanning
Real-time scanning gives you continuous protection against viruses and
riskware items as files are opened, copied, and downloaded from the
Web. Real-time scanning functions transparently in the background,
looking for viruses whenever you access files on the hard disk, diskettes,
or network drives. If you try to access an infected file, the real-time
protection automatically stops the virus from executing.
Manual Scanning And Scheduled Scanning
When the real-time scanning has been configured to scan a limited set of
files, the manual scanning can be used to scan the full system or you can
use the scheduled scanning to scan the full system at regular intervals.
Automatic Updates
Automatic Updates keep the virus definitions always up-to-date. The virus
definition databases are updated automatically after the product has been
installed. The virus definitions updates are signed by the F-Secure
Anti-Virus Research Team.
Host Intrusion Prevention System
The Host Intrusion Prevention System (HIPS) detects any malicious
activity on the host, protecting the system on many levels.
Integrity Checking
Integrity Checking protects the system against unauthorized
modifications. It is based on the concept of a known good configuration -
the product should be installed before the server or workstation is
connected to the network to guarantee that the system is in a known good
configuration.
You can create a baseline of the system files you want to protect and
block modification attempts of protected files for all users.
