Hello,
System.ini is a command that's a part of Advanced Msconfig and you can check out this helpful
article for more information.
Please run your Windows Defender to check the inst.exe file because it's an executable file that may probably harm your computer. You can also schedule a scan on your own time using these steps:
- Search for and open Schedule tasks.
- In the left pane, expand Task Scheduler Library > Microsoft > Windows and then scroll down and double-click the Windows Defender folder.
- In the top-center pane, double-click Windows Defender Scheduled Scan.
- Select the Triggers tab, and then select New.
- Set your time and frequency, and then select OK.
Hope this helps and let us know if you have any questions.
