Understanding Full Antivirus Scan Mode Support

The Kaspersky Lab scan engine supports two modes of scanning:

• scan-all—This option tells the scan engine to scan all the data it receives.
• scan-by-extension—This option bases all scanning decisions on the file extensions found in the traffic in question.

When scanning content, you can use a file extension list to define a set of file extensions that are used in file extension scan mode (scan-by-extension). The antivirus module can then scan files with extensions on the scan-extension list. If an extension is not defined in an extension list, the file with that extension is not scanned in scan-by-extension mode. If there is no extension present, the file in question is scanned.

When using a file extension list to scan content, please note the following requirements:

• File extension entries are case-insensitive.
• The maximum length of the file extension list name is 29 bytes.
• The maximum length of each file extension entry is 15 bytes.
• The maximum entry number in a file extension list is 255.
