F I L E M A S K
Representation of a file name and extension using wildcards. The two standard wildcards used in file masks are * and ?,
where * represents any number of any characters and ? stands for any single character. Using these wildcards, you can
represent any file. Note that the name and extension are always separated by a period.
H
H A R D W A R E P O R T
Socket on a hardware component of a computer in which a cable or a plug can be connected (LPT port, serial port, USB
port).
H E A D E R
The information in the beginning of a file or a message, which is comprised of low-level data on file (or message) status
and processing. In particular, the email message header contains such data as information about the sender and
recipient, and the date.
H E U R I S T I C A N A L Y ZER
Technology designed for detecting threats that cannot be identified using the Kaspersky Lab application databases. It
allows detecting objects suspected of being infected with an unknown virus or a new modification of known viruses.
The use of a heuristic analyzer detects up to 92% of threats. This mechanism is fairly effective and very rarely leads to
false positives.
Files detected by the heuristic analyzer are considered suspicious.
H OOK
Subcomponent of the application responsible for scanning specific types of email. The set of interceptors specific to your
installation depends on what role or what combination of roles the application is being deployed for.

iChecker is a technology that increases the speed of anti-virus scans by excluding objects that have remained
unchanged since their last scan, provided that the scan parameters (the anti-virus database and settings) have not
changed. The information for each file is stored in a special database. This technology is used in both real-time
protection and on-demand scan modes.
For example, you have an archive scanned by Kaspersky Lab application and assigned the not infected status. The next
time the application will skip this archive, unless it has been altered or the scan settings have been changed. If you
altered the archive content by adding a new object to it, modified the scan settings or updated the anti-virus database,
the archive is re-scanned.
Limitations of iChecker technology:
this technology does not work with large-size files since it is faster to scan a file than check whether it was modified since
it was last scanned;
the technology supports a limited number of formats (exe, dll, lnk, ttf, inf, sys, com, chm, zip, rar).
I N C O M P A T I B L E A P P L I C A T I O N
An antivirus application from a third-party developer or a Kaspersky Lab application that does not support management
through Kaspersky Small Office Security.
