• Encrypted credentials required to access each repository.
When an AutoUpdate task is performed, a connection is made to the first enabled repository
(update site) in the repository list. If this repository is not available, the next repository is
contacted, and so on until a connection is made, or until the end of the list is reached.
Proxy servers are used as part of the Internet security to hide Internet users' computers from
the Internet and improve access speed by caching commonly accessed sites. If your network
uses a proxy server, you can specify which proxy settings to use, the address of the proxy
server, and whether to use authentication. Proxy information is stored in the AutoUpdate
repository list. The proxy settings you configure apply to all repositories in the repository list.
The location of the AutoUpdate repository list depends on your operating system. For example,
for Windows XP:
C:\Documents and Settings\All Users\Application Data\McAfee\Common Framework
Configuring the repository list
The repository list includes the repositories from which you retrieve updates. Create and configure
as many repositories as you need. Some sites can be used all the time while others are used
only occasionally.
To access the AutoUpdate Repository List properties:
• From the VirusScan Console, select Tools | User Interface Options.
NOTE: This feature is not available from the ePolicy Orchestrator console.
Configure the options on the tab. For option descriptions, click Help on the tab.

How rolling back DAT files works
If you find your current DAT files are corrupted or incompatible, you can roll back the DAT files
to the last backed up version.
When you update DAT files, the old version is stored in this location: <drive>:\Program
Files\Common Files\McAfee\Engine\OldDats. When you roll back the DAT files, the current DAT files
are replaced with the version in the OldDats folder, and a flag is set in the registry at this
location: HKEY_LOCAL_MACHINE\SOFTWARE\McAfee\DesktopProtection\szRolledbackDATS. Once the
roll back occurs, you cannot go back to the previous version again. The next time an update
occurs, the DAT version in the registry is compared with the DAT files in the update repository.
If the new DAT files are the same as those in the registry, no update occurs.
