Solution to NAV causes IIS to fail to call FSO

symptom:
When you browse the ASP page that calls FileSystemObject,
The request to the page is stopped and eventually causes the page to time out in the browser.

This problem is due to the Script Blocking of Norton Antivirus software
The feature prevents script operations from accessing the file system, such as using FileSystemObject.
This problem not only exists in ASP web applications, but it also occurs in other technologies, e.g.
Windows Script。

Note: This issue still occurs even when Norton Anitvirus is banned.

solve:
To resolve this issue, please contact the Norton Antivirus Software Support Center.
