I get "file has been damaged or deleted" error message while installation (there is some corruption the files ) | It is ad poster and that is the reason why your antivirus can find it suspicious. You should temporary disable Norton Security Suite antivirus if you get "file has been damaged or deleted" error message. Right-click on the tiny Norton Anti-Virus icon in the System Tray (next to the clock) in the lower right-hand corner of the screen, then click on Disable Auto-Protect with the left mouse button.

You can also add Exclusion for the program. Open Antivirus and click
Settings -> antivirus -> scan and risks (tab) -> Exclusion -> items to exclude (from scans and auto protect) and add the program's folder (usually C:\CLAPoster)
