1. Download and Install Autoruns:

   Visit the Microsoft Sysinternals website and download the latest version of Autoruns.
   Extract the downloaded ZIP file to a folder of your choice.

9. Regular Checks:

   It’s a good idea to use Autoruns periodically to check for any new or unusual entries.

   Customized scan: Allows you to choose specific folders to scan.

4. Run the Scan:

   Select the type of scan you prefer and click Next. The scan will begin.
   Depending on the scan type and the size of your hard drive, the process can take several minutes to a few hours.
