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 rollback 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 rollback 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.
Rolling back DAT files
To revert your DAT files version back to the previous version use the Rollback DATs tool.
Task
For option definitions, click Help in the interface.
1 From the VirusScan Console, select Tools | Rollback DATs.
2 Click Yes to proceed with the DAT rollback.
NOTE: This feature is not available from the ePolicy Orchestrator console.
3 Configure the options on the tab.
Excluding scan items
Each of the VirusScan Enterprise scanners allows you to fine-tune the list of file types scanned.
For example, you can exclude from scanning individual files, folders, and disks. These exclusions
might be needed because the scanners could scan and lock a file when that file is being used
by a database or server. This could cause the database or server to fail or generate errors.
