[. . . ] once at specific time (hours: minutes) and date (day-month-year), set the switch on the 1st scheduler page to One time only; 5. in all of the above click Next and set additional execution settings on the 2nd scheduler page. at PC startup, set the switch on the 1st scheduler page to When my computer starts; 2. at shutdown, the switch on the 1st scheduler page to When my computer shuts down. If you need to disable automatic scheduled execution: 1. on the 1st scheduler page set the switch to Disable scheduled clean-up. 1. 6. 7 Renaming Clean-up Variants Enabling/disabling separate component clean-up and selecting clean-up settings, you set-up and customize your PC clean-up variant(s) as needed. That said, you will want to rename the variant(s) it to better represent PC clean-up contents. If you want to rename a PC (or separate component) clean-up variant you can do this by following one of these methods: 1. selecting Rename from the context menu of a PC (component) clean-up variant. Acronis PrivacyExpert 21 As a result of any of these actions you will see the Rename Item window enabling you to enter a new name for PC or component clean-up variant. 1. 7 Data Clean-up Algorithms Unlike most software providing the confidentiality of PC and Internet activity, Acronis PrivacyExpert not only deletes Windows sections (files, folders, registry components, etc. ) it also performs a thorough low-level clean-up of hard disk sectors containing Windows components selected for cleaning. Trace Windows data and files are cleaned with the help of integrated data destruction algorithms. Five of the algorithms meet national data destruction standards: (1) American: DoD 5220. 22-M, (2) American: NAVSO P-5239-26 (RLL), (3) American: NAVSO P-5239-26 (MFM), (4) German: VSITR, (5) Russian: Russian Standard, GOST P50739-95. Besides algorithms that meet these national standards, Acronis PrivacyExpert provides two far more powerful pre-defined algorithms offered by top information security specialists: (6) Peter Gutmann's algorithm; (7) Bruce Schneier's algorithm. After using the most powerful clean-up algorithms of Acronis PrivacyExpert, the disk data can in no way be recovered by any modern methods including the most powerful magnetic microscopy!The user is also provided with a simple, but fast algorithm to use in less important situations: (8) Fast. The algorithm operation is baseb on multiple rewriting of hard disk sectors containing user data with chains of logical 0 and 1. For more information on the algorithms see Appendix A «Hard Disk Wiping algorithms». There you will also find information on the number of hard disk passes, provided by each algorithm, and numeric chains written in the process (see A. 2 «Algorithms Used by Acronis PrivacyExpert »). 22 Chapter 1 : Installing and Starting to Work with Acronis PrivacyExpert Chapter 2. Complex PC Clean-up Using variants of complex PC clean-up described below, you can clean a large number of various Windows components that keep evidence of your PC activity. Vice versa, if you need to clean-up only a specific Windows component, for example, last visited Internet pages, you should use one of the Acronis PrivacyExpert sections, described below (see Chapter 3 «Separate PC Components Clean-up»). Separate component clean-up is faster than any variant of complex PC clean-up. 2. 1 Entire PC Clean-up If you need to clean a PC of any evidence of your activity, select the Entire PC clean-up. Executing it, you'll be able to clean all Windows components accessible by Acronis PrivacyExpert: 1. clean Windows registry from user activity evidence; delete temporary files from standard Windows folders; delete any file types from user folders on any disks connected to the PC; clean Windows Recycle Bin; clean Windows swap file; clean hard disk free space; clean the last visited pages and last used documents list; delete the evidence of searching for files on connected disks, for networked computers, for information on the Internet; clean Internet cache; 10. Entire PC clean-up is executed by a mouse-click on its name in the right part of the main window (for other execution methods see sections 1. 6. 3, 1. 6. 6). [. . . ] Generally speaking, a 1 written to a hard disk is read as 1 by its controller, and 0 is read as 0. However, of you write 1 over 0, the result is conditionally 0. 95 and vice versa ­ if 1 is written over 1 the result is 1. 05. However using special equipment, one can easily read the «underlying» sequence of 1 and 0. It only requires specialized software and inexpensive hardware to read data «deleted» this way by analyzing magnetization of hard disk sectors, residual magnetization of track sides and/or by using current magnetic microscopes.
