I've read many articles about cleaning IE histories,and most of them prefer to use Privacy Expert suite because it can destroy index.dat and cannot be found any records with "IE history viewer"or something else.But one of my friends has found that there is a kind of software which can reveal all the web surfing records even after formating the disk and reinstall XP.That means when a person browses some websites,not only be recorded at the ie folders but also be recorded deeply under the operation system,maybe at the very beginning of the FAT.And someone has programmed a kind of software which searches not the index.dat,not the current operating system,but from somewhere else.So,all the softwares which aimed at wiping IE history doesn't effect with such kind of searching.Or we can conclude that such softwares don't search existed files in the current operating system but deep with the hard disk.While most of wiping softwares aims at wiping the files located in current system. My friend has tried trackseraser,acronis privacy expert suite,Privacy Eraser Pro,CyberScrub Privacy Suite and other similar softwares but none of them can effectively delete surfing records thoroughly. Does anyone know what kind of methods the software used which can examine the surfing records even after formating the whole disk? Only low level format can truely wipe the traces now. I hope privacy expert can improve its function to do this.Thanks I am not an English speaker,so maybe I cannot express myself very clearly.If so,tell me,and I will explain further more.
