Anyone can correct me if I'm wrong, but it's reputation based. No reputation is red flagged as much as a bad reputation. In short the files are too new. I have to disable (does it for 15 min automatically) my anti-virus to run the demos.
We scan all the files hosted on Share, but sometimes there can be false positives. I don't know of any confirmed malware ever being on the site, but I guess it's possible. Some scanners will detect different things than others.
What software are you using that flags the software, and which specific games have the problem?
I had to put my Oculus / Oculus Games and Demos folders in exception list on the Norton program since I was getting that same false positive from every single demo, it also happens with updates from Grey Dog Software games. Now everything works perfectly fine 🙂
