Local Install Triggering BitDefender Phishing Protection?

Hello,

Does anyone know of a technical reason that ERPNext (both v14 and develop) would trigger BitDefender Antivirus to block access to the page because it has recognised it as a phishing site?

It’s a local install, no SSL as it’s used within a local intranet only. The PCs accessing it are Windows 10 Pro, and it’s only a recent thing because I have been using ERPNext for the last year. Both v14 and Develop branches are up to date.

I’ll get the AV modified to remove this issue, but I was more curious as to the technical reason.
