I ran across an unexpected Avast Software folder and file in my (user)\AppData\Local folder. It appears to have been created last October. The Avast folder only has a single file "datascan.json", and it is occasionally modified. I have never had an Avast product installed on this computer. Are this folder and file due to Norton's merger with Avast? i.e., do others of you using Norton in Windows have this Avast "datascan" file in your (user)\AppData\Local\ folder?
I opened the file using Notepad, but it provided no clue. I wonder what the "datascan.json" is doing. Is it some kind of telemetry file?
