Gen:NN.ZexaE.32250.Nu0@auaXuHhi virus?

my antivirus (bitdefender) beeps every time I try to open the game. and steam shows a "Access denied" message. is this a false positive? because I tested on virustotal and shows that there are 5 other antivirus detecting too. https://www.virustotal.com/gui/file/99e474721f91cc992f6714f9f0071961d9cce974836a5485a70239f7ea701d31/detection

Of course it's a false positive. Make an exception to the game file.

I wouldn't be so quick to call it a false positive. My bitdefender says "threat name: gen:suspicious.cloud.2.Nu0@auaxuHhi"

the clue's in the name. weirdly, I didn't get this on my PC where I use malwarebytes, only on my laptop

edit: I googled suspicious.cloud.2 - seems to be a trojan horse that's been around for a while. what's this about? are the devs trying to give us malware?

Thank you for reporting this!

We get the same result when we upload the Windows exe to that website.

These certainly are false positives.

We compared the SHA1-Hashes of the files installed through Steam with the hashes of the files we originally uploaded to Steam and they match.
Which means that the files we are installing through Steam are the same ones we uploaded to Steam for distribution.
Therefore we can rule out any problem on Steam's side.

Although we can never rule out that our own build pipeline is compromised, this almost certainly is not the case.

We had similar problems in the past with false positives (e.g. https://steamhost.cn/steamcommunity_com/app/684410/discussions/0/2534848209913571775/).

Unfortunately virus scanners are not accurate tools.

This may not give you certainty, but here is some information on how we generated the SHA1 hashes if you want to play around

Windows Command Prompt
certutil -hashfile "C:\Program Files (x86)\Steam\steamapps\common\Bridge Constructor Portal\Bridge_Constructor_Portal.exe"
3bf7365bdc9fa4719edf03e194f75673ff75f0d4

macOS Terminal
shasum "/Users/USERNAME/Library/Application Support/Steam/steamapps/common/Bridge Constructor Portal/Bridge_Constructor_Portal.app/Contents/MacOS/Bridge_Constructor_Portal"
55f72ddd5a9e7c6bd9433ea73549922a593f7b40

Linux Terminal
sha1sum "/home/USERNAME/.steam/steam/steamapps/common/Bridge Constructor Portal/Bridge_Constructor_Portal.x86"
5f72a6c0e531f551c2c490e97dafab91a51f2f72
sha1sum "/home/USERNAME/.steam/steam/steamapps/common/Bridge Constructor Portal/Bridge_Constructor_Portal.x86_64"
74eeeb045ee433a019f3113d7a85b82d5eb6140b

The SHA1-Hashes are of the following versions currently released on Steam

Windows "v5.0 Steam_PC r166"
macOS "v5.0 Steam_Mac r138"
Linux "v5.0 Steam_Linux r87"

The version is visible in the game's options menu in the lower right corner.

Thanks and please continue reporting any issues you may find.
