Internet Explorer stores navigation and browser history, cookies and temporary data in the protected file WebcacheV.dat. This file cannot be deleted easily and so if you wish to erase google history, or any other browsing history, this makes it difficult. WebCacheKiller is an easy to use app which allows you to delete this file, and hence will delete browsing history that may not be deleted, even when internet explorer says it has deleted it. Webcache.dat is also responsible for generating the warning of Insufficent Disk Space, and corrupting the hard drive. If you wish to erase google search history completely, then this is the app for you.
