CHAPTER 10. FREQUENTLY
ASKED QUESTIONS
This chapter is devoted to the most frequently asked questions users have
pertaining to the installation, setup, and operation of the Kaspersky Anti-Virus;
here we shall try to answer them in detail.
Question: why does Kaspersky Anti-Virus cause a certain decrease of
server performance noticeably loading the CPU?
Virus detection is a purely computational (mathematical) problem con-
nected with structural analysis, checksum calculation and mathematical
data conversions. Therefore processor time is the main resource con-
sumed by the anti-virus software. At that each new virus added into the
anti-virus database increases the overall scanning time. That is a forced
compensation for security and safety of your data.
Unlike other anti-virus products, which expediate scanning by excluding
less easily detectable or less frequent (in the geographic location of the
anti-virus vendor) viruses from their databases, as well as file formats
that require complicated analysis (e.g. PDF), Kaspersky Lab believes
that the purpose of its anti-virus is to provide real anti-virus security for
its users instead of imaginary, since you cannot be semi-protected. In
reality, "partial protection" is even worse than no protection at all (be-
cause in the latter case users take personal precautions).
Kaspersky Anti-Virus makes its users feel maximum protection. Of
course, Kaspersky Anti-Virus software package allows experienced us-
ers to accelerate anti-virus scanning at the cost of overall security by
disabling scanning of various file types, but we do not recommend doing
so for users who want the best protection.
Question: why is a license key required? Can my Anti-Virus work with-
out it?
Kaspersky Anti-Virus will not work without a license key.
If you haven’t yet made a decision whether you wish to buy Kaspersky
Anti-Virus, we can provide to you a trial key, which will work for two
weeks or one month. The key will be blocked when that period expires.
