how to remove virus from computer using cmd ?

Removing a virus from a computer using Command Prompt (CMD) can be tricky, and it's not always recommended. However, there are some basic steps you can follow to try to remove a virus using CMD:

Start your computer in Safe Mode by pressing F8 while the computer is booting up. This will start Windows with only basic services and drivers, which may help to prevent the virus from running.
Open Command Prompt as an administrator by right-clicking on the Command Prompt icon and selecting "Run as administrator."
Run a virus scan using your installed antivirus software. If your antivirus software is not able to remove the virus, you can use CMD to try to remove it manually.
Type "netstat -ano" into the Command Prompt and press Enter. This will display a list of all active connections on your computer, along with the associated process IDs (PIDs).
Look for any suspicious connections or processes that you don't recognize, and note down their PIDs.
Type "tasklist" into the Command Prompt and press Enter. This will display a list of all running processes on your computer, along with their PIDs.
Look for any suspicious processes that you don't recognize, and note down their names.
Type "taskkill /PID [PID]" into the Command Prompt, replacing "[PID]" with the PID of the suspicious process you want to stop. This will attempt to stop the process.
Type "cd /d [folder path]" into the Command Prompt, replacing "[folder path]" with the path to the folder where the virus is located. This will navigate to the folder.
Type "del [filename]" into the Command Prompt, replacing "[filename]" with the name of the virus file. This will delete the file.
Type "exit" into the Command Prompt to close it.

Note that these steps may not always work, and there is a risk of accidentally deleting important system files. It's always recommended to use an up-to-date antivirus software and to seek professional help if you're not sure how to remove a virus from your computer.
