Sandboxing is an important security technique that isolates programs, preventing malicious or malfunctioning programs from damaging or snooping on the rest of your computer. The software you use is already sandboxing much of the code you run every day.
You left out Avast, which has a built in sandbox as well. Personally I run DeepFreeze, Sandboxie and Avast. I know, someone is going to say either you cannot do that or why do that. I did it by playing with the programs and getting them to actually work well together. I am running them to keep crap off my system, and since I have seen things try and bypass the sandbox, I installed Deepfreeze. All I have to do is turn off the computer, and the problem is gone.
However I have to make an amended point concerning internet browser sandboxing. Sandboxing with Internet Browsers is highly ineffective. This is one of the primary entry points for Malware and other dangerous related infections.
