|
|
|
Your secure computer anywhere
|
|
|
To use Tails, shut down the computer and start on your Tails USB stick instead of starting on Windows, macOS, or Linux.
|
|
|
You can temporarily <strong>turn your own computer into a secure machine</strong>. You can also <strong>stay safe while using the computer of somebody else</strong>.
|
|
|
Tails is a [[!inline pages="inc/stable_amd64_iso_size" raw="yes" sort="age"]] download and takes ½ hour to install. Tails can be installed on any USB stick of 8 GB minimum. Tails works on most computers less than 10 years old. You can start again on the other operating system after you shut down Tails.
|
|
|
You don't have to worry about the computer having viruses because Tails runs independently from the other operating system and never uses the hard disk. But, Tails cannot always protect you if you install it from a computer with viruses or if you use it on a computer with malicious hardware, like keyloggers.

Amnesia

|
Tails always starts from the same clean state and <strong>everything you do disappears</strong> automatically when you shut down Tails.
|
|
|
Without Tails, almost everything you do can leave traces on the computer:
|
|
|
Websites that you visited, even in private mode
|
|
|
Files that you opened, even if you deleted them
