I should have actively scanned the zip file right after downloading. For the heck of it I ran the offline version and then this Trojan popped up.
I ran a full scan with MS Defender but nothing found. Things didn't feel right starting a few months back. No virus found automatically nor did anything show up in automated monthly scans. Worked fine on my Win10/64 with all updates. I downloaded and started using this every once in a while about a year ago.
