Configuring SpIDer Mail

The default settings are optimal for most uses. Do not change them unnecessarily.

The following settings allow you to configure additional mail scanning parameters:

•Heuristic analysis – in this mode, special methods are used to detect suspicious objects infected with unknown viruses with high probability. To disable the analyzer, clear the Heuristic analysis check box.

By default, SpIDer Mail attempts to cure messages infected with a known and (supposedly) curable virus and moves incurable and suspicious messages as well as adware and dialers to Quarantine at the same time ignoring all other minor threats. Other messages are transmitted unchanged by SpIDer Mail (skipped).

You can select one of the following actions applied by SpIDer Mail to detected threats:

Action	Description
Cure, move to quarantine if not cured	Instructs to try to restore the original state of the message before infection. If the message is incurable, or the attempt of curing fails, the object is moved to quarantine. Available for Infected messages only except Trojan programs that are deleted on detection. This is action is not applicable to files within archives.
Cure, delete if not cured	Instructs to try to restore the original state of the message before infection. If the message is incurable, or the attempt of curing fails, the object is deleted.
Delete	Instructs to delete the message. The message is not sent to recipient; the mail client receives a notification about this.
Move to Quarantine	Instructs to move the message to the special Quarantine folder. The message is not sent to the recipient; the mail client receives a notification about this.
Ignore	Instructs to pass the message to the mail client as usual, i.e. without performing any action.

If an email contains a malicious object, any reaction except Ignore results in failure to send the message to a mail server or recipient.

To increase security above the default level, you may select the Move to quarantine action for Unchecked messages, and then scan the moved file with Dr.Web Scanner.

If you want to disable scans of email by SpIDer Mail, ensure that SpIDer Guard monitors your computer constantly.

After performing reaction you configured, SpIDer Mail can display a notification in the notification area. If necessary, you can configure desktop and email notifications.

In this group, you can configure additional actions to apply when SpIDer Mail processes messages.

Option

Description

Insert 'X‑Antivirus' heading into messages

This option is enabled by default.

Instructs SpIDer Mail to add scan results and information on Dr.Web version to message headers after processing. You cannot edit data format.

Delete modified messages on the server

Instructs to remove messages to which Delete or Move to Quarantine action was applied by SpIDer Mail. The messages are removed from mail servers regardless of the mail client settings.

You can set the condition under which SpIDer Mail should acknowledge too complicated messages, whose scanning is time-consuming, as unchecked. To do that, enable the Message scan timeout option and set the maximum message scanning time. After the expiry of the specified period, SpIDer Mail stops check of the message.

Enable the Scan archives option if you want SpIDer Mail to scan the archived files, transferred via email. The following parameters will be available to cofigure:

•Maximum file size to extract. If an archive size exceeds the specified value, SpIDer Mail does not unpack and check the archive.

•Maximum compression ratio. If an archive compression ratio exceeds the specified value, SpIDer Mail does not unpack and check the archive.

•Maximum archive nesting level – the maximum nesting level for archived files. If a nesting level is greater than the specified value, SpIDer Mail proceeds unpacking and scanning the archive until this limit is exceeded.
