Sandboxie is an essential part of my system. I use it daily. You can run your browser in it so if you contract a rogue virus, it doesn't affect your computer. Just close the sand box and it is gone. It is kind of like running a virtual machine without having to install an OS. If you do a lot of downloading and installing of apps, or download a lot of torrents, or just want to be safer than what you are, I highly, highly recommend Sandbox. It is a great app and I guarantee you won't be dissapointed. It has been around since around 2004 and I have been using for the past 3 years. Download the trial and use it. If you like it, buy it, if not get rid of it. I or anyone else will never know if you like something. Everyone has different opinions. I gave you mine about it and now if you get the trial you can get your own.
