APPENDIX A. FREQUENTLY
ASKED QUESTIONS
This chapter is devoted to the most frequently asked questions from users
pertaining to installation, setup and operation of the Kaspersky Anti-Virus; here
we shall try to answer them here in detail.
Question:
Is this possible to use Kaspersky Anti-Virus with anti-virus
software supplied by other manufacturers?
In order to avoid conflicts we recommend that you uninstall ant-virus soft-
ware of other manufacturers prior to installation of Kaspersky Anti-Virus.
Why does Kaspersky Anti-Virus cause a certain decrease in server
performance, noticeably loading the CPU?
Virus detection is a computationally intensive mathematical problem
requiring structural analysis, checksum calculation and mathematical data
conversions. Processor time is therefore the main resource consumed by
the anti-virus software, and each new virus added to the anti-virus
database increases the overall scanning time. This is a necessary
sacrifice for the security and safety of your data.
Other anti-virus products speed up scanning by excluding both viruses
which 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) from their databases.
In contrast, Kaspersky Lab believes that the purpose of its anti-virus
applications is to establish real and complete anti-virus security for its
users. We believe that "partial protection" is even worse than no
protection at all, because it forces users to take personal precautions.
Kaspersky Anti-Virus gives its users maximum protection. Experienced
users can, of course, accelerate anti-virus scanning to the detriment of
overall security by disabling scanning of various file types, but we do not
recommend doing so for users who want the best protection.
For maximum user protection, Kaspersky Anti-Virus recognizes more than
700 formats of archived and compressed files. This is essential for anti-
virus security, because harmful executable code may be hidden inside
files of any recognized format. However, despite the daily growth in the
number of viruses detected by Kaspersky Anti-Virus (approximately 30
new viruses appear daily) as well as the ever increasing number of
recognized file formats, each subsequent version of our product functions
