Betta ransomware removal instructions
What is Betta?
First discovered by Jakub Kroustek, Betta is one of many high-risk ransomware-type viruses and originates from the Dharma family. This ransomware encrypts most data and adds the ".[firstname.lastname@example.org].betta" extension to every encrypted file. For example, a file named "1.jpg" becomes "1.sample.[email@example.com].betta" when encrypted. Encryption renders affected files unusable. If your computer has been infected with the Betta ransomware-type virus, you will encounter a pop-up window titled "All your files have been encrypted!".
According to the "All your files have been encrypted!" pop-up window, files have been encrypted due to supposed security problems with the computer. Cyber criminals (Betta developers) state that, if users want to restore their files, they need to contact them via the email address provided. Betta developers offer free decryption of one file as 'proof' that they can be trusted. To decrypt the remaining encrypted files, they demand payment of a ransom in Bitcoins, however, the cost of file decryption is not stated (this supposedly depends on how quickly victims contact cyber criminals), and the cryptography used to encrypt files (usually, symmetric or asymmetric cryptography). Cyber criminals encourage victims not to rename encrypted files or try to decrypt them using third party software. They claim that these attempts will only increase the cost of decryption, however, these (and other) cyber criminals should never be trusted. Typically, they ignore victims even if the demands are met and ransoms paid. People are often scammed into paying money to cyber criminals for nothing in return. Unfortunately, there is no way to decrypt files encrypted by Betta free of charge (there are no free tools capable of doing this). The only way to restore them is to use an existing backup.

As mentioned in the introduction, Betta is just one of many ransomware-type viruses. Other similar viruses of this type include Charm, FilesLocker, and Katyusha. These viruses are developed by different cyber criminals, but most share an identical purpose: to encrypt files and make ransom demands. In most cases, the only differences are the algorithm to decrypt files and the cost of decryption/ransom amount, however, the biggest problem is that most cyber criminals use cryptographies that generate unique/individual decryption keys. These are stored on a remote server that can be accessed only by cyber criminals. Unfortunately, it is impossible to decrypt the files manually, without Betta developers' involvement. If the virus is not developed and contains bugs/flaws, this may present a chance of decryption. Due to the existence of these ransomware viruses, you are advised to regularly create data backups, and to keep them stored on a remote server or unplugged storage device. If not, backups might be encrypted with other regular data.
How did ransomware infect my computer?
It is not known exactly how Betta developers proliferate this ransomware-type virus, however, there are few most common ways. Typically, they are distributed using spam email campaigns, trojans (malicious programs), P2P (peer-to-peer) networks, third party software download channels, and fake software updaters/update tools. Spam campaigns deliver malicious attachments that, if opened, download malware. Trojans are malicious programs that cause chain infections and, once installed, proliferate even more viruses. Various untrustworthy software download channels (freeware download websites, free file hosting sites) and P2P networks (eMule, torrents etc.) often present malicious software as legitimate software. Users are tricked into downloading malware rather than legitimate software. Fake software updaters/update tools usually infect systems when they exploit outdated software and associated bugs/flaws, and download (and install) malware rather than the updates.
How to protect yourself from ransomware infections?
Take precautions - browse the web and download/install/update software with care. Emails and attachments sent from unknown/suspicious addresses should not be opened. Carefully analyze each email attachments and open it only when you are sure that it is trustworthy. Do not download (or install) software using third party downloaders or installers. These are usually monetized by promoting (bundling) untrustworthy/rogue applications. Download software using official, trustworthy sources only, and using direct links. Keeping software updated is important, but use only tools that are provided by official software developers and not third party updaters. Finally, have reputable anti-virus/anti-spyware software installed and enabled at all times. If your computer is already infected with Betta, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Betta ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Betta ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Betta are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Betta ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
