Abstract
Processes and techniques for protecting web users from malicious executable code are described. A proxy engine is implemented that intercepts communications between a web browser and a script engine. The proxy engine can invoke a variety of custom event handlers that are configured to handle specific types of events (e.g., script events) that occur in the processing of web content. A script shield event handler detects the presence of script in pre-defined script-free zones and prevents the script from being executed on a user's device.
