Why after running a Norton scan does it show a "ZIP archive corrupted" at the end of every file in Windows?

Why after running a scan does it show a “ZIP archive corrupted” at the end of every file in Windows?

Can you post a screenshot showing the files with this message?

What kind of scan did you run? Quick Scan, Smart Scan? If a Smart scan you may be seeing the scare tactics Norton is using to try to get you to purchase more features to “fix your problems”.
