If mail anti-virus protection is enabled, Kaspersky Anti-Virus scans the body of the message, all file attachments in any format and embedded OLE objects. You can disable scanning of the listed objects as required.
When scanning multi-volume archives, Kaspersky Anti-Virus processes each of them as a separate object. Malicious code can be detected only if it is wholly contained in one of these volumes. If code is divided into parts across several volumes, it cannot be detected during scanning. Therefore, it is recommended that multi-volume archives be scanned after being saved on the hard drive by the Anti-Virus application on the computer.
To select mail protection objects:
If a check box is not selected, the relevant objects will not be scanned.
