CHAPTER 16. FREQUENTLY
ASKED QUESTIONS
This chapter is devoted to questions most frequently asked by users regarding
the installation, setup, and operation of Kaspersky Security for Microsoft
Exchange Server 2003. We will try to answer them here in detail.
Question: Can the application be used with other vendors' anti-virus
software?
Kaspersky Security 5.5 for Microsoft Exchange Server 2003 is an anti-
virus e-mail application designed to be used in corporate networks.
Therefore, it can be used together with Kaspersky Lab's anti-virus
applications included into Business Optimal and Corporate Suite
software packages (for example, Kaspersky Anti-Virus 5.0 for Windows
Workstations, Kaspersky Anti-Virus 5.0 for Windows File Servers),
deployed in the network.
In order to avoid conflicts we recommend that you remove any third-
party anti-virus software before you install Kaspersky Security 5.5 for
Microsoft Exchange Server 2003.
Question: Why does the application cause a certain decrease in my
computer performance and impose a considerable load on the
processor?
The process of virus detection is a purely computational (mathematical)
task that involves analysis of structures, checksum calculation and
mathematical data transformation. Therefore, the main resource con-
sumed by the anti-virus application is the processor time. Moreover,
each new virus added into the anti-virus database adds to the overall
scanning time. This is the price that computer users pay for the security
of their data.
Unlike other anti-virus software vendors that speed up the scan process
by excluding from their databases viruses that are less easily detectable
or less frequent in the geographic location of the anti-virus vendor and
file formats that require complicated analysis (e.g. PDF files), Kaspersky
Lab believes that the purpose of an anti-virus application is to deliver to
its users a genuine anti-virus security.
Kaspersky Security allows experienced users to accelerate the anti-virus
scanning process to the detriment of the overall security by disabling
