The windows demo is a standalone 32 bit executable. The installer version is only available for premium users. I might toggle some features to test what is tripping the antivirus, it would be much nicer if they told me what the categories mean (what do I do with Trojan.Malware.300983.susgen???).
How are you checking the access time? File Explorer's "Properties" window changes the access time in Windows 10, that tripped me up during development.
