Administration with Web Console
By default, the heuristic scan is enabled for
inbound mails and disabled for outbound and
internal mails.
The heuristic scan may affect the product
performance and increase the risk of false
malware alarms.
Proactive virus threat
detection
Select whether Proactive Virus Threat Detection
is enabled or disabled.
Proactive virus threat detection can identify new
and unknown e-mail malware, including viruses
and worms.
When proactive virus threat detection is
enabled, the product analyzes e-mail messages
for possible security threats. All possibly harmful
messages are quarantined as unsafe.
Unsafe messages can be reprocessed
periodically, as antivirus updates may confirm
the unsafe message as safe or infected.
When proactive virus threat detection is
disabled, mails are only scanned by antivirus
engines.
