It was the browser, and I'm also using Firefox. I knew the chances of the these files being malicious were basically none (Specially since I had a few of them) but I still found it very odd and wanted to see whats up. Also this was happening with ALL swf type resources, so there wasn't much point in me linking any particular ones.
If it helps, this is how I create my files (For refrence, I made the Nitocris and Melody mods in that list in Hank's image) :
I export the swf files directly from Adobe Animate, use the loader template thing (and only added the necessary parts to the settings, so no special code) and load them directly in Resources with no editing or different host.
So I'd assume your scanner would have to see all loader .swf files from "Resources" as malware/virus (unless this isn't the common way to do that anymore). Or me and Samoth are doing something 'wrong' or using an old version of Adobe Animate or something like that. Hard to tell what your scanner doesn't like tbh.
Btw. did that problem only occur recently? K, nvm, you said "today" (3 days ago).
If yes, does your scanner also dislike other things uploaded by me? What about other (older) resources?
The false positive warning stopped happening since then. Really donnu what it was all about. Like I said, I was 100% sure there wasn't anything malicious within the files but I thought I'd discuss it regardless. Just some pretty weird stuff I guess :P
