Yes, there can be. The weird thing is that it only detected something while running. The game locked up. Windows said something about the color scheme. I used task manager to kill it, and Avast said I had to reboot to quarantine the threat.
I scanned my pc again with avast, malwarebytes, and another proggy. Then. I downloaded inch by inch again and scanned the zip. I unzipped it again and scanned all the files with three different scanners as above. They found nothing.
So either Avast is nuts or the inch by inch program somehow downloads or assembles the virus as it runs.
Anyway, now I'm too scared to run it again.
