In a copyright lawsuit, you would lose. I know it just seems like I'm being a dick at this point, but I was a programmer with HP for 22 years so I naturally feel that giving credit when credit is due is important. Even if the Infection source is open source (which I think it is), proper credit would be nice. So I'll consider this proper credit to the Infection author!
