As explained in our documentation about [[the fingerprint of *Tor Browser* in Tails|doc/anonymous_internet/Tor_Browser#fingerprint]], Tails provides anonymity by making it difficult to distinguish a particular user amongst all the users of <span class="application"> *Tor Browser</span>* (either in Tails or on other operating systems).

It is technically possible to use Tails to create other onion services, but it is complicated and notwe have no plans to documented yet this.
Adding [*Signal*](https://signal.org/) is very high in our priorities but complicated because *Signal* is not available in Debian by default and updates very often.
Because no single app will ever meet the needs of all our users, we might also make it easier to install other messaging apps. ([[!tails_ticket 14567]])
In Tails, you can already chat over XMPP using [[Pidgin|doc/anonymous_internet/pidgin]] and create anonymous chat rooms using [[OnionShare|doc/anonymous_internet/onionshare]].
You can follow this tutorial to [install *Signal Desktop* on Tails](https://0xacab.org/about.privacy/messengers-on-tails-os/-/wikis/Signal/Install-Signal-desktop) and link to an existing *Signal* account.
To create a *Signal* account for a new telephone number from Tails, follow this tutorial on [registering an account using `signal-cli`](https://0xacab.org/about.privacy/messengers-on-tails-os/-/wikis/Signal/Registration-and-Provisioning-via-signal-cli).

No, as other Linux systems, Tails doesn't require an antivirus to protect itself from most malwares, such as viruses, trojans, and worms. There are various reasons why Linux operating systems generally don't need antivirus softwares, including the permission design of Linux systems.
