That's pretty strange, as it sounds like the first time it's happening. If it's the browser itself, I have no idea what it's picking up especially as these are zip files (weird coincidence if compression happened to create a line of bytes in common malware databases), but it's definitely lying. Between v1.2 and v1.2.1, the only file that's actually changed is crop_and_claw.pck and even then it was minor. If it's the OS (probably Windows) then it's especially lying and honestly I have no idea how to deal with Windows and the constant issues that keep cropping up exclusively around it.
