3.1.2.4 Active Directory / LDIF
Avira AntiVir Exchange does not make any changes or additions to the Active Directory.
However, Avira AntiVir Exchange does read various information from the Active
Directory.
When started, the Avira AntiVir Exchange service determines the available Global
Catalog server, which is used, for example, for resolving addresses in distribution lists
during e-mail processing.
The AntiVir Exchange Management Console uses the Active Directory to select
sender/recipient conditions.
If an Active Directory is not available – for example because the corresponding ports are
not open – an LDIF file can be used. This can, for example, be created through an LDAP
export from an Active Directory, an Exchange 5.5 user directory or a Notes Name and
Address Book (NAB).
3.1.2.5 Compressed Files and Archives: Avira AntiVir
Exchange Unpacker
Files are often compressed (zipped) before being sent by e-mail. To allow compressed
files to be scanned for viruses, Avira AntiVir Exchange unpacks the files before running
the scan. An unpacker is automatically installed with Avira AntiVir Exchange.
The unpacker supports the following archive formats:
- ACE
- CAB
- ZIP
- Selfextracting ZIP
- ARJ
- Selfextracting ARJ
- TAR
- GZIP
- TGZ (Tape archive)
- UUE (Executable compressed ASCII archive)
- LZH (LH ARC)
- RAR
- Selfextracting RAR
- Java Archive (.jar)
- BZIP2
Note: Archives can themselves contain further archives. By default, such
recursively compressed files are decompressed to a nesting depth of five levels.
All archives exceeding this nesting depth are moved to the badmail folder.
The standard upper limit for an e-mail including unpacked files is 500 MB. Such a limit is
particularly important to handle so-called ZIP of Death attacks.
The recursion depth and the space restriction can be changed in the console under
General Settings - AntiVir Servers Settings - Properties - General tab.
