2. SYSTEM REQUIREMENTS

   This version of Eraser runs on Windows 95, 98, NT 4.0, 2000
   and later.

   2.1. Libraries

        It may be necessary for you to update the following
        dynamic link libraries before installing Eraser.

        These files were not included in the archive because of
        their size and because they are part of Windows 98/2000
        and are included with many applications including
        Internet Explorer. You can download an update at
        
        http://www.tolvanen.com/common/


        2.1.1. COMCTL32.dll

               You must have version 4.72 or later version of
               the Windows Common Control Library in order to
               use the new Eraser user interface.

               If you are using Windows 95 or NT and have not
               installed Internet Explorer 4.01 or later, you
               must download an update. Windows 98 and 2000
               come with the updated library.

        2.1.1. MFC42.dll and MSVCRT.dll

----------------------------------------------------------------
3. HOW TO INSTALL & UNINSTALL

   3.1. Before installing

        Be sure to uninstall any previous version of Eraser
        before installing. Also make sure you have the required
        libraries installed before running setup (see section
        2.1).

        If the setup program asks you to reboot Windows after
        installation, you must do that before running Eraser.

   3.2. Installing

        SETUP.EXE is a self-extracting executable containing the
        program files.

        Run SETUP.EXE to install Eraser. The setup program will
        extract the files and copy them to a desired location.

   3.3. Help?

        After installing, you can open the help file (in the
        Eraser directory) by double-clicking the ERASER.HLP
        file.

        If the help file does not answer your question, do not
        hesitate to contact the author (see section 5.1).

        You can also get answers to some frequently asked
        questions and read a step-by-step installation
        instructions at Eraser home page (see section 5.2).

   3.4. Uninstalling

        You can uninstall Eraser normally via Control Panel,
        Add/Remove Programs. You should not remove the files
        manually because the settings in the registry would not
        be removed.

----------------------------------------------------------------
4. DESCRIPTION

   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 making it
   impossible to recover the data.

   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
   up to one hundred times.
