Question: Can an intruder replace my anti-virus database?
All anti-virus databases are supplied with a unique signature verified by
Kaspersky Anti-Virus when the program tries to use them. If the signa-
ture does not match the signature assigned by Kaspersky Lab or it is
stamped by a later date compared to your license expiry date, Kas-
persky Anti-Virus will not use this database.
Question: will Kaspersky Anti-virus work under my Linux OS version?
Resuming downloading in case of a disconnection. Now you do
not have to download over again those updates that you al-
ready received if a disconnection from the network occurred.
The size of cumulative updates has been cut in half. The cumu-
lative update contains the entire anti-virus database, therefore
its size considerably exceeds the size of a regular update. The
new service uses a special technology that allows using the da-
tabase you already have for the cumulative update.
Downloading updates from the internet has become faster. Now
Kaspersky Anti-Virus selects the Kaspersky Lab's updates
server located in your region. Additionally, the load on the serv-
er will be distributed in accordance with their throughput, which
means that you will not be connected to an overloaded server
while another server is idle.
The use of key "black lists". This allows preventing updates to
be performed by those users who do not have license for using
Kaspersky Anti-Virus. Therefore properly licensed users will not
suffer from overloaded servers.
For corporate products, the ability to create local updates serv-
ers has been implemented. This function is needed for organi-
zations that use a single local area network comprised of com-
puters protected by Kaspersky Lab's applications. In this case
any computer may be used as the updates server to receive
updates from the internet, place them into a local directory and
provide access to this directory to all other computers in the
network.
