BitDefender says it blocked a virus:
Gen:Variant.TDss.49 located in Unity.exe
It’s the 1st virus since I bought this system 3 years ago.
Somebody know what is going on here?
Thats called false positive. BitDefender thinks, basing on its known patterns etc, that there is a virus in while there is none in
Thanks for the reply.
Apparently there is a piece of code in Unity that looks or behaves like a Trojan. Not saying Unity is malware though, but it doesn’t give any reason to “feel safe” about it.
Also the Kaspersky gives a false warning that Unity contains a keylogger.
same with F-secure… (Gen:Variant.TDss.49)
GEN.VARIANT.TDSS.49
Problem here with F-secure aswell 
I apologize for resurrecting this thred from the underground, but, I just tried to export a unity PC/MAC project to show a collegue, but my and his computers also complain about heuristic trojan virus !
Built with: Unity Pro 4 Trial version for Mac.
I tried my self on a PC with windows without antivirus installed, and it tooks 2 minutes on a Quad Core, to show up the Quality panel, and this is just a 19 MB executble+data project.
What the heck!?!?
If you have a large amount of static data in the code, for example some large arrays that have static initializers, this can sometimes cause false positives.
Since it is often pretty easy to break this kind of thing up or initialize such arrays at app startup instead, you might want to give that a quick try and see if it helps.
Arrays ?
Maybe I have n. 1 script that use arrays, I can’t believe this results in a false positive!
But now you gave me an idea, and I will try with an empty project with just a spinning object and see what the pc says.
Meanwhile, thanks for your infos !
i got the Gen:Variant.tedy
