Normally you can give Window Washer 10/10 for what it does BUT as Webroot haven't updated it it over 2 years it's a bit cheeky calling it 2010. Also it DOES NOT clean your browser history in Firefox since it changed from Firefox 2.0. You need to clean history manually in Firefox. Easy to do just don't expect Window Washer to do it! I guess webroot don't sell as many copies of this as spy sweeper hence why no upgrades, but if they ever sort out the Firefox bug it's great!
You can also create an eraser disk (cd or floppy) to DELETE ALL DATA on your hard drive should you wish to sell on your pc with an EMPTY hard drive so it is worth buying for this also.
Not perfect, but still a RECOMMENDED BUY! :)
