Download Sandboxie to protect yourself from malware and mistakes
Sandboxie is one of the greatest “sandbox” application, being easy to use and powerful. Sandboxie is free but with nags, urging you to buy it.
Think of your PC as a piece of paper. Every program you run writes on the paper. When you run your browser, it writes on the paper about every site you visited. And any malware you come across will usually try to write itself into the paper. Traditional privacy and anti-malware software try to locate and erase any writings they think you wouldn’t want on the paper.
The Sandboxie sandbox works like a transparency layer placed over the paper. Programs write on the transparency layer and to them it looks like the real paper. When you delete the sandbox, it’s like removing the transparency layer, the unchanged, real paper is revealed.
Sandboxie should certainly be complemented by the more traditional anti-virus and anti-malware solutions. These solutions can let you know if your system does become infected in any way. Typically, those other solutions employ various forms of pattern matching to discover malicious software and other threats. Sandboxie, on the other hand, quite simply does not trust any software code enough to let it out of the sandbox.
The combination of the two approaches should keep malicious software — which is serving the interest of other unknown parties — out of your computer.
You should be able to run most applications sandboxed, such as web browsers, mail and news readers, instant messengers and chat clients, peer-to-peer networking, games, in particular, online games which download extension software code. You can even install most applications into the sandbox.
Sandboxie works on all of the recent versions of Windows and needs only a small amount of memory. Sandboxie extends the operating system (OS) with sandboxing capabilities by blending into it. Applications can never access hardware such as disk storage directly, they have to ask the OS to do it for them. Since Sandboxie integrates into the OS, it can do what it does without risk of being circumvented.
Your system (outside the sandbox) must not have been already compromised by an installed key-logger. Sandboxie can not protect against key-loggers that are already running outside the sandbox.
