In this example, we want to delete the keylogger file that resides in the system32 directory (we wish malware was so easily identified). As with most files in this directory, the permissions deny us access to the file so we can't delete it even with administrative privileges.

To change permissions or a file or folder perform the following steps:

  1. In Explorer, right-click on the folder name or file name and select Properties.
  2. Click on the Security Tab.
  3. In the Groups or user names box, select the group that fits. For example Administrators.

  4. Click on the Advanced button.
  5. Select the Group or Users who you wish to change the permissions. You may need to be an Administrator to make these changes.

  6. Click on Edit button.
  7. Another almost identical screen appears with a few additional options (not shown). Click the Edit button again. Now you can actually make the changes necessary!

  8. In the lower Permissions for SYSTEM box, change the permissions. For example, to provide full control, make sure a checkmark appears in the Allow column for Full Control and remove checkmarks in the Deny column if present.
  9. With the permissions set correctly, click on Ok .
  10. Within some folders (but not all) you'll get a warning message. Be sure to click Yes or your changes will be discarded!

A command line utility cacls.exe is used to view and set the owner of a file. You will need to be an administrator to make Access Control List (ACL) changes. The following steps can be used to view and set the file's ACL:

  1. Open a command line box by selecting Start, Accessories, Command Prompt.
  2. At the command prompt type cacls, followed by the path and filename of a file you can access (not the one you are having problems with). This shows you the current owners and the user access rights. For example, on a default XP system, entering cacls c:\Windows\Notepad.exe, the results would appear similar to:

    BUILTIN\Power Users:C

  3. In this system there are three owner categories, called Users, Power Users and Administrators. The letter following the owner category is one of four types, R for Read-only, W for Write, C for Change (also write), and F for Full control.
  4. Run cacls on the file with the problem. If the owner rights are too limited or there are no owners associated with the file, you can fix it using the /G (Grant) option. For Notepad, if we wanted the Users owner category to be able to read/write
