Web Shield - Script scanning
Manage these settings at: Menu ▸ Settings (gear icon) ▸ Active Protection ▸ Web Shield ▸ Customize ▸ Script scanning
Script scanning blocks malicious scripts. This includes remote threats from the web and outside sources, and local threats saved to disk or in the browser cache.
Script scanning can also detect and block malicious scripts that come from HTTPS (encrypted) connections.
Use the check-boxes to select which applications to scan. If any program is unchecked, Script scanning is turned off for that application only.
