Chapter 5. Updating The Anti-Virus Database - KAPERSKY ANTI-VIRUS 5.7 - FOR NOVELL NETWARE Administrator's Manual

CHAPTER 5. UPDATING THE
ANTI-VIRUS DATABASE
The procedure of searching out and removing viruses is based on the records of
the anti-virus database, which contains descriptions of every virus known at the
time, along with methods of cleaning the files infected by them.
Keeping the database up-to-date is of the utmost importance since new viruses
appear every day. We recommend that you update the anti-virus database
immediately after installing the application since the database included in the
distribution package will be outdated from the moment you install the program. In
Kaspersky Anti-Virus 5.6 for Novell NetWare, the anti-virus database is updated
by creating and running the update tasks.
The Anti-virus database updating module deals with database updating. It is
included in the application's server part. When executing the update task the
server connects to the Internet or to a shared directory at the scheduled time,
downloads the anti-virus database updates, and saves them in a special
directory. Then the updates are distributed to the servers included in the mailing
list and saved in the directories for storing the used anti-virus database. Backup
copies of all the updated objects are created.
Prior to updating the anti-virus database, the updater automatically creates a
backup copy of all data from the directory containing received updates. The copy
will be placed in the special Backup directory so that the last update can be
rolled back, if necessary.
To do this, the user must copy the anti-virus database from the back-up directory
(the default location is SYS:\KAV\BASES\BACKUP) to the current database
location (the default directory is SYS:\KAV\BASES)
To ensure that the server that executes the update task updates its own anti-
virus database it must be included in the mailing list along with the other servers.
To ensure the server is able to save the anti-virus database in the directories of
the servers it updates, it must have access rights for the file systems of these
servers.
All the tasks can be started either manually at the user's (administrator's)
request, or using the scheduler. The task scheduler allows tasks to be started at
any desired time and also allows the duration of the task execution to be
specified. Executing the tasks requires Kaspersky Anti-Virus or Anti-virus
database updating module to be running on the server.
