With this button, you can enable / disable Mail Anti-Virus.
If the button is green, Mail Anti-Virus runs when the operating system is started. It is loaded in the RAM of the computer and scans email messages transmitted via the POP3, SMTP, IMAP, MAPI, and NNTP protocols, as well as email messages sent over secure connections (SSL) via the POP3, SMTP, and IMAP protocols.
If the button is red, Mail Anti-Virus is disabled.
By default, the button is green.
In the Security level section, you can select one of the predefined collections of settings (security levels) for Mail Anti-Virus. The decision of which security level you should select depends on operating conditions and the current situation.
When this security level is selected, Mail Anti-Virus applies maximum scrutiny to email messages. Mail Anti-Virus scans incoming and outgoing messages and attached archives, and performs heuristic analysis with the Deep scan level of detail.
The High security level is applied when working in a dangerous computing environment. An example of such an environment is a connection to a free email service from a home network that is not guarded by centralized email protection.
This security level ensures the optimum balance between operating system performance and security. When the Recommended security level is set, Mail Anti-Virus scans incoming and outgoing messages and attached archives, and performs heuristic analysis with the Medium scan level of detail.
This is the default security level.
When this security level is selected, Mail Anti-Virus scans incoming messages only and performs heuristic analysis with the Light scan level of detail. Attached archives are not scanned. If the Low security level is set, Mail Anti-Virus scans email messages at maximum speed and uses up fewer operating system resources.
The Low security level is used when working in a reliably protected environment. An example of such an environment might be a corporate network with centralized email security.
Clicking the link causes Kaspersky Internet Security to apply the Recommended security level. The link is displayed if you have modified the email scan settings in the Advanced settings of Mail Anti-Virus window, except for the settings in the Connectivity section.
In the drop-down list, you can select the action that Mail Anti-Virus performs when an infected or probably infected object is detected.
This value is available in the list and is selected by default if interactive protection mode is enabled.
Before attempting to disinfect or delete an infected object, Mail Anti-Virus creates a backup copy in case there is a later need to restore the object or possibility of disinfecting it.
This value is available in the list and is selected by default if automatic protection mode is enabled.
Denying access to an object from third-party applications. A blocked object cannot be read, executed, modified, or deleted.
