Script scanning and how it works

The script scanner operates as a proxy component to the real Windows scripting host component. It intercepts scripts, then scans them before they are executed.

For example, the script scanner confirms:

  • If the script is clean, it is passed on to the real scripting host component.
  • If the script contains a potential threat, the script is not executed.
Trusted processes and also websites that utilize scripts can be excluded from inspection.
Note: On Windows Server 2008 systems, Script Scan URL exclusions do not work with Windows Internet Explorer unless you click the checkbox Enable third-party browser extensions to enable the setting and restart Windows Server 2008.
