Just downloaded the latest nw.js from https://www.scirra.com/nwjs and getting an error "The file is a decompression bomb" from Avast scan.
Version nwjs-for-c2-v0-13-0-beta5
FYI
Kaspersky didn't find anything, and Avast is renowned for false positives.
If really worried, try it on Jotti Scanner.
Yeah Avast can be a bit over sensitive on times.
Don't fancy uploading a 130 mb file to jotti as the kids are currently playing online and don't think I can stand the calls of "Lag....."
Just installed it with no problems. Must be Avast
Avast will actually cause C2 games with NWjs to crash or fail to start.
It false flag it and attempts to run the code in a sandbox environment.
Develop games in your browser. Powerful, performant & highly capable.
Avast did pop up first time I ran NWjs. Now it behaves itself.
