So, still at risk from:
“Drive-by” that exploits a software security hole
Malicious java script, Flash animations, etc.
Both exploit weaknesses in poorly written software that enable Spyware, Hijacks, Worms, Bots, etc. to be put on your computer, directly from a Webpage

that isolates any application running inside it, from the rest of your computer.
After running your application, delete the sandbox and all traces of the application are also deleted.
So, if we open our Internet Browser inside a sandbox, then any malware that tries to enter our computer, either by accidentally “clicking” the wrong thing, or by a drive-by, will be trapped inside.
The sandbox I will show you today, is a freeware program called Sandboxie
Can be downloaded from www.sandboxie.com

A Sandbox!

Desktop’
Sandboxie will allow you to “recover” these files
Other folders can be added to be recovered
