Thank you for the quick reply.
I did see the Fortinet phishing detection when I first checked VT a few days ago. It didn't come up when I checked again a day or so later, but did show a malicious detection by CRDF. I've never seen the Quttera one before your reply, and your report shows CRDF as clean. I just did a new VT search & only Fortinet phishing pops, and Quttera & CRDF are now clean! I didn't pursue the VT detections because they were so inconsistent. However, I just signed up on VirusTotal & rescanned, and now I see a 3rd detection: Comodo Valkyrie Verdict, also for phishing, as well as Quttera & Fortinet (link). I guess I need to dig deeper.
Thanks again for your help.
