There are a lot of history cleaners around but this is the only one I've found
(so far) that removes Persistent Identification (PIE), the new technology that's
being used in place of cookies because we remove cookies and advertisers are
hell bent on tracking us.
HistorySweep is a simple, yet powerful, privacy
protection tool which removes the browsing history trail that is created on your
machine when you surf the internet. Your web browsers built in privacy functions
will NOT completely and securely delete ALL of your history files, leaving them
vulnerable to recovery. HistorySweep will protect your privacy in four of the
top web browsers on the market (Internet Explorer, AOL Browser, Netscape, and
Opera) eliminating your history files beyond all practical recovery. The
automation features included in HistorySweep will automatically remove your
history files each time you boot your machine and/or each time you close all of
your web browser windows. As an extra bonus HistorySweep will also speed up your
machine and free up hard drive space by allowing you to remove temporary Windows
files which are no longer needed.
