I've had the, if I recall, 1.2.0.zip file be labeled as malware from several sources [google, microsoft, malwarebytes, + more], even including my browser, firefox, stopping it from even downloading. [3rd time I have ever seen firefox stop and prevent download]
So, I simply didn't download it, luckly for me, the game was later updated and released, which said updates .zip wasn't flagged by any of the stuff I listed above... I did FORGET to run the actual .html file through them! maybe I'll try uploading the .html file to virus total... found ZERO so seems ok. [I don't even know if virustotal can find stuff hidden in javascript code in part of an html file]
Sadly, now, both 7zip and winrar have very VERY bad exploits, though I think the newest versions of 7zip and winrar fixed/patched/updated to stop those exploits now.
