exiftool.exe false positive?

Opened Geosetter, which advised me that a new version of exiftool was available (ver 10.21). Clicking ok to install, Norton Security with Backup popped up and quarantined the said tool. It also prompted for a reboot. Since new versions appear almost every other week, I was wondering if this was a false positive. This is the report created:
