Protection supports detection of .alz and .egg compressed files in both inbound and outbound
email traffic. Once extracted, file contents are scanned by the Advanced Threat Scan
Engine (ATSE) and Virtual Analyzer (if enabled) according to the configured virus
policy rules.
Additionally, for inbound emails, if File Password Analysis is enabled, encrypted
.alz and .egg files will be decrypted using the retrieved password, then scanned by
ATSE and Virtual Analyzer (if enabled), ensuring comprehensive protection against
hidden threats.
