Block Malicious File Downloads is a Chrome add-on designed to prevent the unintentional downloading of harmful files. This tool serves as an additional security layer, offering protection against accidental clicks that may lead to malware infections. It effectively blocks a wide range of file types commonly exploited by malicious software, including executable files (.exe), scripts (.js, .vbs), and various installation packages (.msi, .msp).

The add-on can be particularly useful in corporate environments, where it can be deployed through Group Policy settings. It is worth noting that the extension does not automatically operate in Incognito mode, prompting administrators to consider disabling this mode via group policy as well. By implementing this tool, users can significantly reduce the risk of downloading harmful files inadvertently.
