Microsoft Security Essentials includes a command-line utility which can be used to update the virus/malware definitions, initiate a scan, undo a recent definition update and perform other tasks. To know how to use the command-line utility, open a Command Prompt window (CMD.EXE) and execute the following command:
"%ProgramFiles%\Microsoft Security Essentials\MpCmdRun.exe" /?
Command | Description |
-? / -h | Displays all available options for this tool. |
-Trace [-Grouping #] [-Level #] | Starts diagnostic tracing |
-RemoveDefinitions [-All] | Restores the installed signature definitions to a previous backup copy or to the original default set of signatures |
-RestoreDefaults | Resets the registry values for Microsoft Antimalware Service settings to known good defaults |
-SignatureUpdate [-UNC] | Checks for new definition updates |
-Scan [-ScanType] | Scans for malicious software |
-Restore -Name <name> [-All] | Restore the most recently or all quarantined item(s) based on name |
-GetFiles | Collects support information |
In addition to the above information, detailed information for each command-line parameter is shown when you run the above command.
To update the MSE virus/malware definitions, use this command:
"%ProgramFiles%\Microsoft Security Essentials\MpCmdRun.exe" -SignatureUpdate
The command-line tool can be useful if you want to update MSE using Batch file, Script or using Task Scheduler.
