i'm trying Sandboxie on my system to see how it runs. it installed ok and runs with no noticable slowdowns there is a little icon in the system tray - right click on it to launch your browser. sandboxie works by creating a [virtual drive] folder - everything downloaded to disk goes in there. no changes are allowed to your real disk. The advantage is that no virus, trojan or spyware downloading via the browser can install itself on your machine - so you can surf the net completely protected. of course you can't download any files you want either or update bookmark files etc as they are lost at the end of a session. (but you can explore the sandboxie virtual drive and move files out - but of course they might contain malwear) at the end of a session just delete the contents of the sandbox and terminate all sandboxed processes. if anyone else is using sandboxie please feel free to add your experiences and thoughts to this thread.
