Hi! Thank you very much for your interest in the demo!
Unfortunately, the only way to get past something like that would be to add Reanimation Scheme to the list of exceptions for Norton Security. I'm afraid I've never used Norton so I'm not familiar with how the process would work, but a Google search may shed more light on the exact steps to add a program to the whitelist to allow it through the antivirus.
Thank you again, and I hope you do get the chance to try the demo some time!
