A military cleaning is the first step when ever a militias software gets to operating on a hard drive. The problem is when this software gets to the place on the hard drive where the system operating software is installed. When operating software gets infected it many times damaged bits in this section of the hard drive. Nothing can be done to repair these damaged bits & the only way to get operating software to operate on this hard drive is to rewrite it so that all is moved to a different location on the hard drive. When this happens replacing the hard drive is the best option. Over time the operating software has been improved & many times prevents this from happening. When new free software is offered online it temps many into think that these are improvement that cannot be resisted by many users. When Foxfire & Google Chrome was first offered there was many free down loads available. These free downloads allow hackers to do many things to a system. Family members in the learning process on computers are the most susceptible to this. Many of you have never used the first Windows, Windows 95, & Windows 98 but the many improvements & changes has been impressive many times.
