Can’t you, as a user of Norton’s product, report it as a safe file? I thought that was something that can be done, and would be more respected than the creator of the file telling them it’s safe. I have Norton on my computers at home, but it’s a version that is free via Comcast. Of course, that doesn’t mean that it’s a pared down version at all. I really enjoy the Identity Safe. I like that it cleans up spurious registry records and temporary files (both Internet and file system temps). I haven’t explored the back up capabilities yet.
I don’t know if it’s the same version you have. I have not had an issue with a file from DAZ3D being blocked as far as I can remember. And I just got the latest freebie recently, too. I think I had one file that was reported as malicious, but it let me ignore it and then I reported it as a safe file. That was several years ago, though.
