These definitions are published more frequently and may not correspond to the versions published to Microsoft Update. Definition updatesThe type of definition update an agent performs is determined by how up-to-date it is with current definitions published by Microsoft.
Agents that have updated recently will download and apply only very small changes whereas new agents will need to download the full definition installation to become up-to-date. Description The full installation is generally only for new antimalware agents or for agents with definitions that have not been updated for more than a month. After download and installation, if computers are kept up-to-date they should not be required to apply the full installation again.
Size Generally, the size is from MB, depending on several factors. These factors include the duration since the last rebase and include the number of changes since the last rebase. Description Agents that are using files of the previous month will receive a binary delta update of the engine and base definitions. The binary delta updates contain only the parts of the base files and of the engine files that have changed since the previous version.
For more information about the Microsoft binary delta update technology used in this package, view the following TechNet article: Delta Compression Application Programming Interface Size Generally, the size of this installation is from MB, depending on several factors. Generally, the size is from MB, depending on several factors. Description The vast majority of definition updates should be applied to agents that are using the engine and base files from the current month.
In this situation, only the delta files MpAvDlta. Agents that are using very recent versions of the antimalware definitions will receive binary differential delta updates to the delta files. The delta installation packages use the same binary delta update technology described previously.
This technology allows the package to contain only the parts of the delta files that have changed since the previous version. This binary delta update technology helps reduce the size of the update file. This occurs because the update file does not redistribute the parts of the base definition and of the engine files that are currently used by the agent. Microsoft may publish several versions of a binary delta update package. Each binary delta update package contains different content.
The goal of publishing multiple package versions is to make sure that agents receive an optimized update for their current update level. Agents that are using the engine and base files from the current month, but have not updated recently enough to be eligible for the smaller delta update, will apply the entire delta files MpAvDlta.
Size Generally, the size ranges of the delta updates are from KB and the entire delta files are from MB, depending on several factors. These updates are designed to protect you from network threats, including exploits as they are transmitted.

On the Evaluation Schedule page of the wizard, select Run the rule after any software update point synchronization.
On the Deployment Schedule page of the wizard, configure the following settings:. Time based on : If you want all clients to install the latest definitions at the same time, select UTC. The actual installation time will vary within two hours.
Software available time : Specify the available time for the deployment that this rule creates. The specified time must be at least one hour after the automatic deployment rule runs. This configuration makes sure that the content has sufficient time to replicate to the distribution points.
Some definition updates might also include antimalware engine updates, which might take longer to reach distribution points. Software update deadlines vary over a two-hour period.
This behavior prevents all clients from requesting an update at the same time. On the User Experience page of the wizard, for User notifications , select Hide in Software Center and all notifications. With this configuration, the definition updates install silently.
