The automatic proxy configuration scripts are used by web browsers to selectively apply proxy server settings for specific web domains. They can also be used to changing the proxy servers dynamically without having to open the browser settings each time you want to switch the proxy servers. The proxy auto-configuration (PAC) scripts are used by many extensions for browsers like Mozilla Firefox for proxy server settings. But many trojans and malware programs also use the PAC scripts to set malicious proxy servers to your web browsers in order to redirect you to phishing websites and steal your personal or financial data.
