Using Kaspersky Anti-Virus
®
for ISA Server
26
•
If an infected file has been detected and disinfected before the
first chunk of data containing a part of this file was sent to the
client, the client receives the disinfected file.
•
If an infected file was detected after the first chunk of data con-
taining a part of this infected file had been sent to the client, the
program terminates the connection. Upon the second request
for this file, the client will be immediately notified that the re-
quested file is infected.
Upon the second request for this file, the client will be notified that the
requested file is infected only if the time span between the first and the
second requests does not exceed 100 sec. This value cannot be
changed in this version of the program.
•
Specify the time span for sending the next chunk of data to the client upon
request in the
Maximum time span between chunks of data sent to the
client, sec
field.
The value of this field cannot exceed the value of the
Maximum scan
time for the first chunk of data, sec
field.
•
Set the percentage of data accumulated by Kaspersky Anti-Virus
®
for
subsequent analysis and scanning in the
Data not sent to the client be-
fore scan completes, %
field.
The
Enable partial content download
checkbox enables partial downloading of
data in cases, for example, of an Internet connection failure when downloading a
file.
However, note that Kaspersky Anti-Virus
®
is able to detect a malicious code only
if the entire code is present in any part of the downloaded file. If the viral code is
divided into separate parts, Kaspersky Anti-Virus
®
might fail to detect it. In such a
case, after the integrity of the downloaded object is restored, the virus might
penetrate your system.
For more information about the fields for editing messages sent to the client, see
section. 4.4 on page 40.
At any time during editing the current settings, you can return to default settings
by clicking the
Set default values
button.
