The most appropriate policy designed specifically to block access to malicious websites is Web Filtering. Web filtering is utilized to manage and control user access to the internet by blocking harmful and malicious URLs based on categorization and reputation. This is crucial for protecting users from phishing attacks, malware distribution, and other web-based threats.

Other options, while related to security, focus on different aspects. Application Control is aimed at managing which applications can be run or accessed on the network. Threat Protection encompasses a broader range of defenses against various types of threats like malware and viruses, but it doesn't specifically target web content. Data Protection focuses on the safeguarding of sensitive information and does not address web browsing safety directly. Therefore, Web Filtering is clearly the specialized choice for blocking access to malicious websites.
