Programs installed via sandboxed browser installed on system

[Uh-Oh]

Hello,

I use Sandboxie daily and have never had any issues with it. Tonight, I recommended that my partner uses it to complete some download offers on a GPT site tomorrow and showed him how it works. After he went to bed, I completed a few offers for him using Firefox 12.0 (Sandboxed - Version 3.74 (64-bit)) then deleted the contents of the default box. I then noticed that there was still an icon on his taskbar for one of the programs I installed and alarm bells started ringing. When I checked, everything I downloaded and installed via the sandboxed browser was on his computer. I have never known this to occur and wonder if you can shed any light, please. He’s using Windows 7 Home Premium (64-bit).

Thanks
