Norton found this in Construct 2 by Scirra (SAPE.Adload.259) I wrote the company and the response that was given was;
It's a false positive. We can assure you that if you are downloading from our website the file contains no viruses.
Unfortunately there's little we can do on our end!
Kind regards,

Is this a true false positive or is it as Norton software says a real virus?
