Can east-tec Eraser securely clean my index.dat files?

The index.dat files are repositories of information such as web addresses, files you have recently opened and search queries. Their purpose is to allow Internet Explorer quick access to some data, such as Autocomplete matches as the user types an Internet address. Also, the index.dat files are always open while Windows is running, so deleting these files requires some special procedures, such as wiping them before loading Windows.

To wipe index.dat files, please follow the steps below:

  1. Open east-tec Eraser
  2. In the left side panel, click Privacy Guard
  3. Click Advanced
  4. Click Next
  5. From the Tab Activation section in the left lower part of the window, check Browsers and uncheck all other tabs (or leave them checked if you want to erase other areas)
  6. Make sure Internet Explorer is checked
  7. Highlight Internet Explorer the list and click Properties
  8. Make sure at least these options are checked: “Eliminate the Internet Explorer History”, “Eliminate the Internet Explorer Cookies”, “Eliminate the Temporary Internet Files”, “Clear list of typed URLs”, “Clear AutoComplete”
  9. Click OK
  10. Click Next
  11. Click Start
  12. At the end of the wiping process, you will be asked to restart the computer. This is required to complete the process.

Why does Privacy Guard require to restart my PC?

Sometimes, after running Privacy Guard, you will be prompted to restart your computer. This is required to wipe files that are always loaded in the computer memory and therefore cannot be wiped while Windows is running. At restart, all “locked” files are unprotected/unlocked and they can be deleted. These are files that are used by Windows or Internet Explorer and they can only be erased while Windows starts.

Examples: One of these files may be the Windows paging file, that may contain sensitive information collected without your knowledge or approval. The Internet Explorer history or cookies, index.dat files are also “locked” while Windows is running.
