Microsoft Office also has a sandbox mode to prevent unsafe macros from harming your system.

PDFs and Other Documents: Adobe Reader now runs PDF files in a sandbox, preventing them from escaping the PDF viewer and tampering with the rest of your computer.

Browser plug-ins, particularly Java, are a frequent target of attacks that use security vulnerabilities to escape this sandbox and do damage. Playing a flash game on a web page is safer than downloading a game and running it as a standard program because Flash isolates the game from the rest of your system and restricts what it can do.

Browser Plug-in Content: Content loaded by browser plug-ins - such as Adobe Flash or Microsoft Silverlight - is run in a sandbox, too.

Web pages can run JavaScript code, but this code can’t do anything it wants - if JavaScript code tries to access a local file on your computer, the request will fail.

Web Pages: Your browser essentially sandboxes the web pages it loads.

Much of the code your devices run every day is already sandboxed for your protection: Sadly, Mozilla Firefox still doesn’t run in a sandbox. By running the web browser with fewer permissions, we gain security.

Even if the web page found a security vulnerability and managed to take control of the browser, it would then have to escape the browser’s sandbox to do real damage. These browsers are programs running on your computer, but they don’t have access to your entire computer. For example, Google Chrome and Internet Explorer both run in a sandbox themselves. Other programs on your computer are also sandboxed. If websites you visit weren’t sandboxed and isolated from the rest of your system, visiting a malicious website would be as bad as installing a virus. They’re restricted to running in your browser and accessing a limited set of resources - they can’t view your webcam without permission or read your computer’s local files. For example, your web browser essentially runs web pages you visit in a sandbox.
