I have avira antivirus running and my specs are:
8 GB Ram, Nvidia Geforce GTX 1070 GPU, AMD A8-5600K Processor and Windows 10 - hope thats enough info!
This is very mysterious. I had my friend who also runs Windows 10 launch the game just to be sure I hadn't made an error somewhere, but it launched fine for him. I think that rules out your OS and your specs.
This is a shot in the dark, but the folder should contain a file called 'options.ini'. You could try opening this in notepad and changing the line 'VertexBufferMethod=1' to 'VertexBufferMethod=2' which is the 'most compatible' option.
Has your antivirus or your firewall said anything about the game?
