Sppsvc.exe - (Microsoft Software Protection Platform Service)
The Software Protection service enables the download, installation and enforcement of digital licenses for Windows applications. You may receive the message “sppsvc.exe wants internet access” when a Program/Application is trying to access the Internet for Downloading/Installing or when there is an update happening in your PC.
I would recommend you not disable the Software Protection service rather; you can scan the file using Virus Total by choosing the proper location.

The legitimate file location is: C:\WINDOWS\system32\Sppsvc.exe
