Kaspersky Anti-Virus 5.6 for Microsoft ISA Server 2004/2006 Standard Edition
To enhance the efficiency in processing large amounts of data, Kaspersky
Anti-
Virus® can simultaneously run several anti-virus kernels. By default,
four anti-virus kernels are formed and run simultaneously during application
startup.
Note:
You can select up to 32 anti-virus kernels to be run simultaneously. It is recom-
mended that you run four anti-virus kernels on one physical processor.
The number of anti-virus kernel instances reserved for scanning
"fast" objects
.
In this field, you can specify the number of anti-virus kernel instances re-
served for scanning some categories of HTTP traffic (the so-
called “fast”
traffic). This allows you to decrease the time spent by Kaspersky Anti-Virus
to scan large objects.
The following types of objects can be classified as HTTP traffic “fast” ob-
jects:
Text files of size less than 2 MB
Graphic files of size less than 2 MB
Other objects (excluding executable files) of size below 256 KB.
Scan queue size
. In this field, specify the maximum number of objects
that can be placed to a working directory for objects queued for anti-virus
scanning.
Note:
The number of queued objects can range from 1 to 16383. The default value is
1024.
Warning!
If the queue is full, a new object will not be scanned. It will be flagged as clean
and sent to the client.
Warning!
In case of multiple simultaneous connections (more than 1000) with an FTP or
HTTP server, the time for scanning some of the queued objects might exceed
the server timeout. In this case, the connections to the server will be terminated,
and all objects will not be delivered to the clients.
Maximum scan time, sec
. In this field, specify the maximum time al-
lowed for scanning a single object.
