Steam putting virus on my computer!!!?

[Squid]

Sorry for the dramatic headline, I did try to find a private way to report this but could not find a link.
Steam updated my virtual pool 4 game today. As I started the game Norton flaged it up as an heuristic virus and deleted the excutable. The game will not play.

Heuristics are notorious for giving false positives

White list it and submit it to Symantec

There are no viruses on steam

To clarify this statement, Steam, and its CDN, perform rigorous virus testing on all files uploaded to their servers. It would be highly improbable, if not straight impossible, for a virus to both be uploaded to their servers, and to be served to users.

Another option is to stop using Norton for a while and try Avira or Avast. Just check what they say

Even better, don't use Norton at all.

Norton does that all the time. Grim Dawn recently flagged also. I'd suggest moving to another AV

We the people recommend that you do this immediately.

Wrong. Not only it's not impossible, I say the chances are that an exploited game is already in-the-wild and we're only going to discover it a few years in the future, perhaps 10 years from now, or never even discover it.

Nothing, and I say NOTHIHG, is impossible to crack. Steam dev's, antivirus engines, Steam's servers, CDN servers... all managed by humans who have to deal with millions of lines of code. We are bound to make mistakes.

Heck, even Microsoft "leaked" the golden keys for SecureBoot.

I'm not going into deep details, but if you think antivirus scans (even with multiple scanners) make it impossible to compromise an OS though a game, then you have a lot to learn about exploitaition techniques. Sure, we trust that big and known companies would simply not risk their business by exploiting a game on Steam, but it's certainly very possible to do so without getting detected throughout many years. A simple and well configured HIPS will show just how much access a game has on a system and will show how much "owned" you can get if a malicious developer pushes a malicious binary, specially on games that have "malware-like" anti-cheats like EasyAntiCheat or ESEA that operate in ring0 and their users will certainly accept any UAC prompt (that is, if the user even has UAC enabled - shame on him/her if not).

Remember, VALVe does NOT have access to the Source Code of the games they publish, and they certainly will NOT decompile them. Not only because it's a tedious and slow process, but it's really prone to error. And asking the developer for the code is a no-go.

The above is done by the game developer, and IMO is the easy way. No antivirus "check" will catch a well-written exploit, be it a driver exploit, a flash exploit (many games need flash for whatever reason), a javaScript exploit, a direct Kernel exploit, etc.

The hard way would be to crack into VALVe's servers. Cracking into the CDN servers would be even harder because you'd have to get them all at the same time, I'm pretty sure they all talk to each other about the checksums of the games files, so if anything changes = red flag is raised.

To the above post. I've had a plenty of trouble with ATI Catalysts and Avast. The last one simply can't read one large file from the Catalyst and treat it as suspicious. Of course we usually trust AMD/ATI but the situation can make anyone paranoid. Indeed there is nothing unbreakable in the world, but there are many false positive flags as well.

[Toquita]

Avast had a lot of issues with false-positives in the past, which is sad considering it's one of my favorites. It can scan through the entire driver package, though, it's just not configured to that by default IIRC.
It has improved a lot over the last years, to the point where it's not far from Avira's scanners, which is one of the best out there.

In my case, my AMD drivers are all Open Source: The Kernel driver (radeon or amdgpu) and the userspace stuff (all the rest, e.g. OpenGL, OpenCL, etc) from mesa.
The only closed-source program I have installed is Steam, which is tighly restriced via Sandboxing technologies (via Firejail) and anti-exploit Kernel protection through GRSecurity.

[Xtenzor]

Well I am not a technical expert but I like Avast interface more over Avira. BTW never had any trouble with nVidia drivers.

[Toquita]

Yeah, AMD has been lacking quality in their drivers since quite a long ago :P

Indeed we do. Don't get me started on Norton.
