 **[Session](https://getsession.org)** | Session is a fork of Signal, however unlike Signal it does not require a mobile number (or any other personal data) to register, instead each user is identified by a public key. It is also decentralized, with servers being run by the community though [Loki Net](https://loki.network), messages are encrypted and routed through several of these nodes. All communications are E2E encrypted, and there is no meta data.
 **[Silence](https://silence.im/)** | If you're restricted to only sending SMS/MMS, then Silence makes it easy to encrypt messages between 2 devices. This is important since traditional text messaging is inherently insecure. It's easy-to-use, reliable and secure- but has fallen in popularity, now that internet-based messaging is often faster and more flexible
 **[KeyBase](keybase.io/inv/6d7deedbc1)** | KeyBase allows encrypted real-time chat, group chats, and public and private file sharing. It also lets you cryptographically sign messages, and prove your ownership to other social identities (Twitter, Reddit, GitHub, etc), and send or receive Stella or BitCoin to other users. It's slightly more complex to use than Signal, but it's features extend much further than just a messaging app. Keybase core is built upon some great cryptography features, and it is an excellant choice for managing public keys, signing messages and for group chats.
+**[Off-The-Record](https://otr.cypherpunks.ca/)** | Off-the-Record (OTR) Messaging allows you to have private conversations over instant messaging. It has fallen in popularity in recent years, in favor for simpler, mobile-based messaging apps, but still widely used and secure. It provides: Encryption (so no one else can read your messages), Authentication (assurance that the correspondent is who you think they are), Deniability (After a conversation, it cannot be proved you took part), Perfect Forwards Secrecy (if your keys are compromised, no previous messages can be decrypted). The easiest way to use OTR, is with a [plugin](https://otr.cypherpunks.ca/software.php) for your IM client
 **[OpenPGP](https://www.openpgp.org/)** |  Provides cryptographic privacy and authentication, PGP is used to encrypt messages sent over existing chat networks (such as email or message boards). Slightly harder to use (than IM apps), slower, but still widely used. Using [GnuPG](https://gnupg.org/download/index.html), encrypts messages following the OpenPGP standard, defined by the IETF, proposed in [RFC 4880](https://tools.ietf.org/html/rfc4880) (originally derived from the PGP software, created by Phil Zimmermann, now owned by [Symantec](https://www.symantec.com/products/encryption)). **Note**  there have been vulnerabilities found in the OpenPGP and S/MIME, defined in [EFAIL](https://efail.de/), so although it still considered secure for general purpose use, it may be better to use an encrypted messaging or email app instead- especially for sensitive communications.

 #### Word of Warning
+For Microsoft Windows, Windows Defender provides totally adequate virus protection in most cases. These tools are intended for single-use in detecting/ removing threats on an infected machine, and are not recommended to be left running in the background, use portable editions where available.
+
 Many anti virus products have a history of introducing vulnerabilities themselves, and several of them seriously degrade the performance of your computer, as well as decrease your privacy. Never use a free anti-virus, and never trust the companies that offer free solutions, even if you pay for the premium package. This includes (but not limited to) Avast, AVG, McAfee and Kasperky. For AV to be effective, it needs intermate access to all areas of your PC, so it is important to go with a trusted vendor, and monitor it's activity closley. Read more about why you shouldn't use [Anti-Spy Tools, on Windows](https://as93.link/gjlj4).
