File Explorer Opening Randomly

Hello everyone. I recently had a strange problem with my Windows 10 PC. In fact, File Explorer opens randomly without any pop-ups. Is it due to a malware attack or something serious? Any help would be appreciated.

I found this by searching some articles online. This is not due to a malware attack, but due to corrupted system files. After following the steps given in the article, my problem has been fixed.

dism+ is a great tool for minor tweaks of windows 10

Run the command prompt as admin and enter DISM /Online /Cleanup-Image /RestoreHealth and skip the 3rd party

Edit : Also sfc/scannow will tell if if DISM is even needed ?
