Advanced Heuristic Analysis and Detection (AHeAD)
enable AHeAD
Your AntiVir program contains a very powerful heuristic in the form of AntiVir AHeAD
technology, which can also detect unknown (new) malware. If this option is enabled, you
can define how "aggressive" this heuristic should be. This option is enabled as the default
setting.
Low detection level
If this option is enabled, slightly less unknown malware is detected, the risk of false
alerts is low in this case.
Medium detection level
This option is enabled as the default setting if you have selected use of this heuristic.
This option is enabled as the default setting and is recommended.
High detection level
If this option is enabled, significantly more unknown malware is detected, but there are
also likely to be false positives.
13.3.1.4. AntiBot
The AntiBot function of MailGuard prevents your computer from becoming part of a so-
called bot-net and being used to send out spam emails: To send spam via a bot-net, an
attacker usually infects a number of computers with a bot that then connects to an IRC
server, opens a particular channel and waits for the command to send the spam emails.
To distinguish spam emails from an unknown bot from genuine emails, MailGuard
checks if the SMTP server and email sender for an outgoing email are included in the
lists of permitted servers and senders. If this is not the case, the outgoing emails are
blocked, i.e. the email is not sent. The blocked email is displayed in a dialog box.
Note
The AntiBot function can only be used, if the MailGuard scan of outgoing emails is
enabled (see the option Scan outgoing emails under MailGuard :: Scan).
Permitted Servers
All servers in this list are authorized by MailGuard to send emails: Emails sent to these
servers are not blocked by MailGuard. If no servers are included in the list, the SMTP
server used to send outgoing emails is not scanned. If the list is populated, MailGuard
blocks emails sent to any SMTP server not included in the list.
Input box
Enter the host name or IP address of the SMTP server you use to send your emails in this
box.
Note
You can find details of the SMTP server used by your email program to send emails in
your email program under the date the user account was created.
Add
You can use this button to include servers specified in the input box in the list of
permitted servers.
Delete
This button deletes a highlighted entry from the list of permitted servers. This button is
inactive if no entry is selected.
