WRT the report, it's probably a false positive. The virus checker is using heuristic scanning for that report (note the "Heur" prefix). Heurisitc scanning just goes by patterns, so it's not really reporting a known virus. You'll need to create an exception for that file in your scanner to keep and use the file on your local system.

I'd like to add one more thing about my 'add an exception' recommendation. Just to cover myself, my employer, and Microsoft, we can't know if the file was actually infected in some way after you pulled it down (or even if GitHub has been compromised in some way). Therefore, my guidance on adding an exception for the file to your virus scanner is a ...

... recommendation. It's ultimately the dev's responsibility to check the file (e.g., checksum, physical check, etc.) to confirm that a file is faithfully correct to its source when adding scanner exceptions. We assume no responsibility if there really is a virus in your local version of the file. (Ok ... 😄 ... the lawyers should be happy now 😀👍.)

I'll probably make that more generic when I reach this topic on my UE pass on #19286.
