Privacy is such a key issue these days, yet we often neglect to think about just how exposed our movements are. Click on the Windows 'Start' menu then highlight 'Documents' - every file you've accessed recently. Now click Ctrl-H - a list of all the web sites you've visited today. Starting to get the picture? Thankfully there are lots of programs out there that can help you shield this information from prying eyes, and Privacy Guardian is one of the most comprehensive I've seen.
The application is a breeze to install and set up, and once running it cleans traces of your activity very thoroughly, including a file shredder to make sure that no one, but no one, sees that you were looking at that Spice Girls web site. Unfortunately there's no stealth mode within the program but Privacy Guardian makes up for this minor shortfall in other ways. For instance, it's the only tracks eraser I know of that can remove all MS Office history, and it has an automatic scheduler that performs clean-ups on startup or shutdown.
This is a highly user friendly application that lets you delete unwanted traces of PC and Net activity without a lot of hassle. Highly recommended.
