How to secure and protect your personal data in 2019

The tools are:
· TrueCrypt: Keep your files safe from prying eyes.
· AxCrypt: to encrypt files or folders one by one.
· Camouflage: hide selected files
· CCleaner: Clean traces (cache, history, temporary files ...)
· SDelete: Prevent recovery of deleted files (zeroing free space)
· Zeroing the Windows swap
With these 4 tools, your tracks will be well cleaned and your privacy protected
(But do not forget to secure your computer!)
TrueCrypt allows you to create encrypted disks. These are virtual disks (which behave like any disk) or real disks. It is even possible to encrypt the windows partition! In the event of an attempt to extort your password, you may have set a secondary password, which will give access to bogus data that you have previously entered. Thus, the person who forced you to give a valid password will have no access to confidential data.

Advantage: The data written in these disks is automatically encrypted / decrypted. At no time are the data written in clear on disk. No need to spend time encrypting / decrypting files to work: It's transparent.
Always use for your personal files (for example everything about your bank).
AxCrypt is an encryption software for password-protected files or folders on Windows. AxCrypt uses the AES-128 algorithm. AxCrypt has the following features:
· Integration with Windows context menus. A single right-click on a file helps to protect it.
· Double-click integration, to open, edit and save encrypted files as simply as unencrypted files.
Since AxCrypt works by file, it is easy to send protected files to recipients by email. It is even possible to make self-extracting files to prevent recipients from having to install AxCrypt.
Camouflage is a utility that is placed in the context menu and allows you to hide selected files by attaching them to any file. The camouflaged file looks and behaves like a normal file and can be saved, used or sent without attracting attention. Thus, you can use an image that looks and behaves just like any other image but contains encrypted hidden files.
CCleaner is a freeware that erases your traces: history, browser cache and cookies (IE, Firefox, Opera ...), Windows history (Recent documents, launched programs, logs, trash, clipboard, etc.)

Before turning off the computer or going away, not to leave unnecessary traces.
CCLeaner Alternatives: Glary Utilities, Wise Registry Cleaner, Easy Cleaner, Free History Eraser.
When a file is erased, only the file name is deleted. The body of the file is unchanged. It is therefore possible with some tools (Restoration, PC File Recovery ...) to recover these files.
SDelete allows you to overwrite the free space of a disk so that this recovery is impossible.
SDelete is much better than most similar tools because it supports NTFS features and can use patterns that prevent most physical recovery operations (opening the hard drive).
To empty the free disk space, type: sdelete -z c:
Do not forget the -z, otherwise your entire disk will be erased.
To be done before shutting down the computer or going away, so as not to leave unnecessary traces.
Or once a week, for example.
Zeroing the swap file
The swap file (also called "virtual memory") is a large file at the root of the disk (pagefile.sys on Windows 2000 / XP) that is used to manage the memory.
It therefore contains copies of the memory of some software, which can reveal information.
Windows has a dump option as standard, but you must manually enable it in the registry:
· Take Regedit
· Go to HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management
· Create a key of type REG_DWORD, name: ClearPageFileAtShutdown, value: 1
Once this option is enabled, Windows will write zeroes on the entire paging file each time you restart or shut down Windows.
If you use XP-AntiSpy (freeware) or SafeXP (freeware), this option is accessible by simply ticking a box:
This operation is automatic, it will be triggered each time Windows is restarted or shut down.
Note that it will take a few more seconds when you close Windows.
With these 4 tools, you will leave virtually no trace. No need to buy expensive erasure software: They will not do better.
Do not forget that all this is perfectly useless if your PC is not secure!
