Chapter 12 - Virus Attacks
Virus Prevention Software
The illustration below, Fig. 12.2, shows the
summary box utilized by Sophos Anti-Virus. In this example, two
viruses have been located and information about each of them and the
circumstances of their detection are displayed. The option of what
to do with the viruses is provided, and a cleaning or purging
utility is usually run to remove the viruses from the system. If
there are damaged or infected files, the program can repair or purge
them and restore them for use.

The importance of updating antivirus software
regularly is stressed by Kraft, “Your antivirus software is only as
good as your most recent update.” This makes a straightforward and
intuitive update process imperative. A program that allows for
scheduling of automatic updates to be downloaded and installed
without any input from the user is the best option for many people.
A program with an ungainly update procedure will likely be
neglected, with potentially disastrous results.
Software Best Practices
As previously mentioned, keeping antivirus
software updated is vital. The updates however, are usually only
available via a subscription service. When the program is purchased
and registered at installation, the owner is automatically enrolled
in the subscription service for a period of time, usually 12
months. During that period, the software can be updated at any
time.
At the end of that period, however, updates
will no longer be available. Attempting to update beyond that time
will result in a message stating that the subscription service has
expired. Usually, a link is provided to a website where the
software can be renewed on the spot. Anyone tempted to save the
cash and not renew the subscription should reconsider. An
unprotected computer is an infected computer. It’s just that
simple.
