HTML Script-inf false positive

I’m trying to access a site that I use regularly, hxxps://www.classicfirearms.com, but today I’m now getting a “safely aborted connection…infected with HTML:Script-Inf [Susp]” notification. Because of this, I cannot access the site. I’ve been on this site plenty of times, I’ve never had issues, and nowhere else have I ever seen anyone reporting any issues. It’s a well-known site that’s been around for years, I’m fairly positive that this is a false positive.

I'm fairly positive that this is a false positive.
