Possible 2 malware files: AVG detected Win64(and 32):Malware-gen - false +?

Good day, 
today my AVG detected 2 files and classified them to be Win64:Malware-gen and Win32:Malware-gen. They were quarantied. 
The first is gfsdk_ssao.win64.dll in The Witcher 3 GOG folder 
The second: libGLESv2.dll in Steam folder

Due to origin of these files I think that they are not malicious and must be false positives. However, I might be wrong and have an infection in my PC,  therefore I kindly ask for your advice and help on this matter.
