Sandboxie is a sandbox-based isolation program for Windows. Sandboxie uses isolation technology to separate programs from your underlying operating system preventing unwanted changes from happening to your personal data, programs and applications that rest safely on your hard drive. Secure your favorite web browser and block malicious software, viruses, ransom-ware and zero day threats by isolating such attacks in the Sandbox; leaving your system protected. Run your favorite email program in Sandboxie so you never have to worry about suspicious attachments or spear phishing attacks. Sandboxie restricts and blocks internet websites and programs from accessing your personal data (i.e. My Documents), files & folders on your system.
