Eraser is an advanced security tool, which allows you
to completely remove sensitive data from your hard
drive by overwriting it several times with carefully
selected patterns.

You can drag and drop files and folders to the on-
demand eraser, use the convenient Explorer shell
extension or use the integrated scheduler to program
overwriting of unused disk space or, for example,
browser cache files to happen regularly, at night,
during your lunch break, at weekends or whenever you
like.

The patterns used for overwriting are based on Peter
Gutmann's paper "Secure Deletion of Data from Magnetic
and Solid-State Memory" and they are selected to
effectively remove the magnetic remnants from the hard
disk.

Other methods include the one defined in the National
Industrial Security Program Operating Manual of the US
Department of Defense and overwriting with pseudo-
random data. You can also define your own overwriting
methods.
