System hacks: Windows Defender quick upgrade scan two-in-one

In general, Windows 10 will automatically update the virus database regularly and perform security checks automatically during the use of the computer. But when it comes to special situations, users need to check manually, they definitely want to confirm the upgrade to the latest virus database and then perform a quick check, which requires first entering the Security Center, and then check the virus database information, which may require a manual upgrade, and then perform the check operation, which is quite troublesome. In fact, for users who often need to check and kill manually, there is a more convenient way – to create a two-in-one shortcut to upgrade and quick scan.

1. Create a two-in-one shortcut for upgrade and quick scan

We are going to use the Windows Defender command file MpCmdRun.exe. MpCmdRun.exe has many command line switches, use the “/?” parameter to run MpCmdRun.exe to view these switches. But today we are going to use an undocumented switch “/SignatureUpdateAndQuickScan”.

First, right-click on a blank space on the desktop and create a shortcut. In the “Please type the location of the object” box, enter the following command (Figure 1).

“C:Program FilesWindows DefenderMpCmdRun.exe” /SignatureUpdateAndQuickScan

Note that the quotation marks in the command are double quotes, and they are separated from the following parameters by half spaces.

Next, enter a name for the shortcut, such as “Automatically Update and Quickly Check for Kills”. Click the “Finish” button to create a desktop shortcut (Figure 2).

By fixing the above desktop shortcut to the Windows taskbar, you can click on the icon at any time and perform virus database updates and automatic quick scans very easily (Figure 4).
