against a new threat. In order to resist new viruses, you should update the
anti-virus databases daily.
Every year Kaspersky Lab increases the frequency of its updates issued
for the anti-virus databases. Currently they are released every hour.
Updating of the application modules is an additional feature that allows
both correction of discovered vulnerabilities and addition of new functions.
Question: What are the changes to the updating service of version 5.0?
The Kaspersky Lab 5.0 application suite features a new updating service
which has been developed in accordance with the requests of our users.
It automates the whole updating procedure, from the preparation of
updates in Kaspersky Lab to the moment that relevant files are updated
on clients' computers.
Advantages of the new updating service include:
Ability to resume downloading of files after disconnection. Upon
reconnection only files which have not been downloaded are retrieved.
Cumulative updates are now half the size. A cumulative update contains
the whole anti-virus database; therefore its size considerably exceeds that
of typical updates. The new service employs a special technology which
allows using an already existing anti-virus database for a cumulative
update.
Accelerated downloading from the Internet. Kaspersky Anti-Virus locates
a Kaspersky Lab's update server located in your region. Furthermore,
servers are allocated according to their performance, so you will not be
sent to an overloaded server while there is another idle server available.
Use of key black lists. Unlicensed and illegal users are now prevented
from using the updating service. Protected users therefore do not suffer
from inability to contact overloaded updates' servers.
Corporate enterprises can now create a local updates' server. This
feature is designed for organizations where a single LAN unites
computers protected by Kaspersky Lab applications. Any computer on the
LAN can be turned into an updates' server that retrieves updates from the
Internet and shares them with the other networked computers.
Is it possible for an intruder to replace the anti-virus database?
Every anti-virus database has a unique signature checked by Kaspersky
Anti-Virus when accessing the database. If the signature is wrong or the
date of the database is later than that of the key expiration, Kaspersky
Anti-Virus will not use it.
