If you share your PC with somebody else, or are concerned about privacy when using your PC at work, you should think of alleviating your fears of being discovered by installing a tool that would erase your surfing tracks, such as CuteShield Internet Eraser Lite.
     CuteShield Internet Eraser Lite is a free utility that lets you erase all imaginable tracks of your surfing activities from Internet Explorer - and all that in one click. The program lets you clear out the browser cache, its cookies, autocomplete fields, history and typed URLs, saved passwords, etc. It also lets you do thourough cleaning on the system itself - remove files from the Recycle Bin, recently open documents, clear out the TEMP folder and suchlike. The thing that distinguishes this utility is that it doesn't just delete all of the above, it erases it from the hard disk completely, so data recovering utilities have no chance to restore it.
     The tool is fully integrated into IE - it appears as just another button on its toolbar. It includes a built-in pop-up blocker and a few other useful features which you are welcome to discover on your own.
