steam file marked as virus

[WayneThePain]

my antivirus marked a steam file as a trojan and removed it, I had been playing rust right before it happened but might be unrelated.

Program Files (x86)\Steam\steamapps\downloading\755790
File:tss-api.dll

It's a false positive, whitelist your entire Steam folder and it wont happen again.

Do not confess blindly in STEAM, which in the past has allowed spyware and even a game that made cryptocurrency mining. Analyze the file that detects you as virus in VirusTotal, you can give you an idea if it is a false positive or not before blindly trusting it.

Nope, there's never been an infected game on Steam. The cryptominer you speak of was a demo hosted off Steam and published as a link on a dodgy developer's Green Light page.

1. This is not a "STEAM file", this is a file from some game or app with the appid you stated.
2. Contact gamedevs on that for comments.
3. Gamedevs are live people - they can get hacked or even intentionally do that - and a trojaned .dll/.exe/... will be uploaded to Steam and distributed across the net. Maybe even with 100% of the gamedev team being unaware of that. In Ukraine and Russia we had "Petya" malware encryptor distributed via law&accounting software :)
4. Of course there can be false positives - AV writers are live people as well.
