1. Open the command prompt as administrator:

Type cmd in the search bar.
Run the command prompt as administrator.
2. Using WMIC (Windows Management Instrumentation Command Line):

List all running processes:
Short WMIC process list
Quickly detect anomalies and identify processes that consume unusually large amounts of CPU or memory.
Get detailed information about a specific process:
wmic process, where /"name='processname.exe'/" list complete
Determine whether a particular process is legitimate or suspicious.

Taskkill command:

Terminate a specific process based on the process ID
taskkill /F /PID 1234
Force terminate malicious processes to prevent them from causing damage.

Check Windows Defender status:
sc query windefend
Make sure the Windows Defender service is active and running.

Update Windows Defender definitions:

Change direction
cd %Programs%//Windows Defender

Trigger an update manually:
MpCmdRun.exe -SignatureUpdate

Keep virus definitions up to date for effective malware detection.
6. Use PowerShell to get security information:

Open PowerShell:
Type powershell in the search bar and press Enter.
Listing security updates
Get-HotFix | Where-Object {$_.Description -like /"*Security*/"}
Identify and install missing critical security updates.
Run scans with Windows Defender:
