There’s nothing wrong with the install or any files, and the Norton “reputation” message isn’t even suggesting there is a virus.

That message is just Norton declaring the file as a “new” file, by its “reputation” assessment. So it doesn’t know enough about it to clear it,
https://community.norton.com/en/forums/clarification-wsreputation1-detection

All that it takes to get flagged these days is a coincidence of a series of bytes matching any of the millions of lists of bytes in the Norton database. With big installs with audio files etc., false positives are a common occurrence.

We will let Norton know at https://submit.symantec.com/false_positive/

Have Fun!
