On startup, before I've clicked a single button other than signing in, Windows gives me a prompt to pick which program I want to open a file with. If I pick a text editor like Notepad or Notepad++, it'll result in the attached text file, which seems to report a ping.
Part of the file says "C:\Program Files (x86)\Nox\" which is a leftover file after I uninstalled a program called Nox. I've since deleted that file, but the mystery file still pops up.
I found someone with a similar problem on the Microsoft Answer forums, but they never seem to have found a solution.
