This may be little known to you that for all the searches that you perform on Google from your system, Google keeps a track on all of those by installing cookies into your system. However this is not used for any wrong purpose.
Google uses this info for preparing reports, checking out most searched keyword and tracking user habits. But if you are sort of a person who would not like to get tracked for your search queries then here is a tool that can help you. The tool is called G-Zapper. G-Zapper helps you stay anonymous while searching Google.
G-Zapper helps protect your identity and search history. G-Zapper will read the Google cookie installed on your PC, display the date it was installed, determine how long your searches have been tracked, and display your Google searches. G-Zapper allows you to automatically delete or entirely block the Google search cookie from future installation.
Using this tool is also very simple, to delete the cookies installed just click on the Delete Cookie button while to block their installation in future just click the Block Cookie button. G-Zapper requires IE and Firefox browsers and is compatible with all versions of Windows.
