Deep ransomware removal instructions
What is Deep?
First discovered by MalwareHunterTeam, Deep is a high-risk ransomware-type virus that originates from the Scarab malware family. After successfully infiltrating the system, Deep encrypts most stored files and appends filenames with the ".deep" extension. For instance, "sample.jpg" is renamed to "sample.jpg.deep". Compromised data immediately becomes unusable. Following successful encryption, Deep changes the desktop wallpaper and generates a text file (named "HOW TO RECOVER ENCRYPTED FILES.TXT"), placing a copy in every existing folder.
The desktop wallpaper and text file contain similar messages stating that data is encrypted and encouraging victims to contact developers if they want to restore it. No additional information regarding the encryption is provided. Therefore, it is currently unknown whether Deep uses symmetric or asymmetric cryptography, however, each victim receives a unique key necessary to restore their data. These keys are hidden on a remote server controlled by Deep's developers. After contacting these people, users are asked to pay a ransom. The cost is also currently unconfirmed - all details are provided via email, however, in most cases, size of ransoms fluctuate between $500 and $1500. Victims are also allowed to attach up to three selected files (less than 10Mb, non-compressed), which then be restored and returned to the victim as a 'guarantee' that data can be restored. Regardless of the cost, do not pay. Research shows that cyber criminals often ignore victims, once payments are submitted. Therefore, paying typically gives no positive result and users are scammed. You are advised never to contact these people or pay any ransoms. Unfortunately, there are no tools capable of cracking Deep's encryption and restoring data free of charge. Therefore, the only solution is to restore everything from a backup.

The Internet is full of ransomware-type viruses that share similarities with Deep. The list of examples includes (but it is not limited to) SHRUG, Predator The Cipher, and CryptoLite. Although these viruses are developed by different cyber criminals, their behavior is identical - all encrypt data and make ransom demands. There are typically just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Unfortunately, these viruses commonly use algorithms that generate unique decryption keys. Therefore, unless the virus is not fully developed or has certain bugs/flaws (e.g., the key is hard-coded, stored locally or similar), restoring data manually without involvement of developers (contacting these people is not recommended) is impossible. Ransomware is one of the main reasons why you should maintain regular data backups, however, remember to store them on a remote server (e.g., Cloud) or unplugged storage device, otherwise backups are encrypted together with regular files.
How did ransomware infect my computer?
|Threat Type||Ransomware, Crypto Virus, Files locker|
|Symptoms||Can't open files stored on your computer, previously functional files now have a different extension, for example my.docx.locked. A ransom demanding message is displayed on your desktop. Cyber criminals are asking to pay a ransom (usually in bitcoins) to unlock your files.|
|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads.|
|Damage||All files are encrypted and cannot be opened without paying a ransom. Additional password stealing trojans and malware infections can be installed together with a ransomware infection.|
To eliminate Deep virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
To prevent ransomware infections, be very cautious when browsing the Internet and downloading/installing/updating software. Carefully analyze each received email attachment. Files that seem irrelevant or have been received from suspicious/unrecognizable email addresses should never be opened. Furthermore, select "Custom/Advanced" settings and carefully analyze each window of the download/installation dialogs. Opt-out of all additionally-included programs. Software should be downloaded from official sources only, using direct download links. Third party downloaders/installers are used to proliferate rogue apps, and thus should never be used. Furthermore, keep installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite. Bear in mind, however, that apps should be updated using implemented functions or tools provided by the official developer only. The key to computer safety is caution. If your computer is already infected with Deep, 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 Deep 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 Deep 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 Deep 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 Deep 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.
