History Eraser App
History Eraser is a single-purpose app that lets you quickly and easily remove key personal information from Chrome.
Just check off any of the app's 22 items, including browsing history, cache, download history and/or cookies; History Eraser will delete them. It can remove any Web-related items for the current session, or you can specify any time between the past hour and the first time you ever used the machine.
You can also set up a custom mix of items or use the program's presets for an Easy, Medium and Hard cleaning. For example, with History Eraser set to Easy, it took 30 seconds for me to clear a month's worth of Web history, cookies and cache data, covering my online tracks.
