I got 200 computer CD games here and I think checking them for viruses would be inappropriate. Also, when I bought software on CD I was always sure there is no virus.
I wonder if there ever was software or a game containing a virus on the optical disc? If this happened by accident or with intent, it doesn't matter.
To not include home-brew software, I am only asking for pressed discs and not burned discs. Also I am only asking for real viruses (backdoor trojan horses) and not, for example, less harmful ad-showing software.
