Files that are named Banner,ads in the project cannot be accessed by the client in a workaround

When a picture is uploaded to the save directory named "banner" or "ads" file, the picture will not be displayed as a workaround,
Because Banner,ads and other words of the directory by some anti-virus software as a protected file, specifically in the anti-virus software "ad set list" option, so installed this anti-virus software
The client will not display the picture under Banner,ads, even not allow access to the file under the directory, the anti-virus software, "advertising filtering" function to screen off the normal display,
But the project directory name is best not named banner, or ads and other advertising-related words,
