Using Kaspersky Anti-Virus
®
for ISA Server
26
When scanning multi-volume archives, Kaspersky Anti-Virus iscans
each of the volumes as a separate object. In this case, the application
can detect malicious code only if one of the volumes contains the entire
piece of code. If a virus is divided into separate parts, during partial data
loading, the anti-virus application will be unable to detect it. In this case,
there is a possibility that malicious code can propagate after the object
restores its integrity.
Multi-volume archives can be scanned after they are saved on the hard
disk by, for example, other Kaspersky Lab applications are installed on
the computer.
Kaspersky Anti-virus does not scan password protected archives!
•
If you want to scan compressed executable files, check the
Scan
compressed executable files
box.
As for archives, if this option is disabled, executable files will be
scanned as uncompressed. The program will detect only those viruses
that have penetrated the compressed file.
Since all these modes increase the load on your computer resources during anti-
virus scans, this can delay sending files to the client.
In the lower part of the tab, you can select the anti-virus database that will be
used to detect viruses:
•
Standard databases (viruses only)
– the application will use the database
containing descriptions of all currently known viruses and methods of their
detection and eradication. This is a default option.
•
Extended databases (v RiskWare)
– in addition to virus
signatures, the database contains descriptions of the so-called riskware,
i.e. the applications that known to be potentially vulnerable to hacker
attacks, nonauthorized access, etc.
•
Redundant database (v RiskWare, SpyWare, AdWare)
– the
application will use the most extended version of the database. In addition
to the above-described database, this version contains descriptions of spy
applications (SpyWare) and applications used to broadcast unsolicited
advertisements (AdWare).
Spy application allow unauthorized users to get access to personal infor-
mation, such as web browser history, passwords, bank accounts, etc., and
send it to interested parties.
The so-called AdWare installed together with other software displays ad-
vertisements in new browser windows, thereby impelling the user to visit
the website of the advertiser. This software may irritate users and lead to
increasing the company’s total traffic.
