We were fans of Window Washer 5, but this latest release gets even better. The professional yet understated new interface is testament to Webroot listening to what users want. You now get the ability to clean traces of the apps you use without damaging them, using over 450 'custom wash' items. If you want to securely erase a hard disk so that no private data is sold along with an old PC, a new System Eraser tool comes to your aid (although not on a per-partition basis like Acronis). There's even native support for Firefox, though Opera is strangely absent from the supported browser list. Good cookie management, secure file erasure and 'bleaching' using DoD, NSA or Guttmann algorithms wrap up the feature set. Used alongside Webroot Spy Sweeper, Window Washer provides an almost perfect privacy package.
