DrWeb ransomware removal instructions
What is DrWeb?
DrWeb is a name of a legitimate anti-virus software. However, some cyber criminals named their ransomware DrWeb too. It is possible that this decision was taken with a purpose to smear the legitimate software's name. One way or another, DrWeb ransomware belongs to Dharma's (another program's of this type) family. The person who discovered it is Jakub Kroustek. Cyber criminals use these programs to generate revenue by encrypting victim's data and forcing them to purchase a decryption tool from them. DrWeb renames all encrypted files, it adds the ".drweb" extension to them. It also appends filenames with victim's unique ID and developers' email address. For example, encrypted "1.jpg" would be renamed to something like "1.jpg.id-1e857d00.[firstname.lastname@example.org].drweb" and so on. It creates two ransom notes: one is displayed in a pop-up window and another one ("RETURN FILES.txt") is placed in folders that contain encrypted data.
"RETURN FILES.txt" contains only a couple of emails (email@example.com and firstname.lastname@example.org) that should be used to contact cyber criminals who developed DrWeb ransomware. The ransom note in a pop-up window says that victims have 7 days to contact them, after that the decryption keys will be overwritten. It means that after 7 days victims will not be able to decrypt their files anymore. To receive the cryptocurrency wallet's address, victims have to contact cyber criminals via one of the aforementioned emails and provide the unique ID which is appointed to every victim individually. The email can contain one files that DrWeb's developers offer to decrypt for free. As stated in the pop-up window, these cyber criminals will send a decryption tool, key and instructions on how to use them as soon as they receive the money (ransom). People are encouraged not to try to decrypt files using any other tools and not to rename any of them. It is mentioned that such actions might cause permanent data loss or increase the price of a decryption. Note, we do not recommend to buy decryption tools from cyber criminals who develop ransomware-type programs. They tend to ignore their victims once they receive the money. In order to avoid possible financial loss, we recommend to restore files using data backup. Most of the times it is the only way to recover files, most ransomware-type programs cause encryptions that are impossible to decrypt without using the right tools. Unfortunately, only particular ransomware's developers can provide their victims with them.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
DrWeb is similar to other programs of this type, such as Qbtex, yG, and Codnat and many more. Most of the times they share two main similarities: they are designed to prevent victims from accessing their data by encrypting it and to keep that way unless a ransom is paid. Main differences usually are cryptography algorithm used for encryption and the price of a decryption tool/key. If a ransomware-type program is not in a development state and does not have any bugs, flaws, then it is very likely that it will be impossible to decrypt its encryption without using the right tool. Typically, cyber criminals (ransomware developers) are the only ones who have it. That is why we recommend to have a data backup created and to store it on unplugged storage device or remove server like Cloud.

To eliminate DrWeb virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
To keep computers/operating systems safe, it is important to browse the web, download, install and update software with care. Attachments (or web links) included in irrelevant emails that are received from unknown, suspicious addresses should not be opened, at least not without analyzing them first. Software should not be downloaded using some third party downloaders, Peer-to-Peer networks or any other tools that we mentioned above. We recommend to download it from official, trustworthy websites and using direct links only. All installed software should be always updated, however, it should be done properly - using tools that are provided by official software developers and not some third party updaters. Various software 'cracking' tools are not legal and cause damage too. They should not be used as well. And finally, it is always a good idea to have a reputable anti-virus or anti-spyware software installed and to keep it enabled at all times. If your computer is already infected with DrWeb, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

YOUR SECRET KEY WILL BE STORED ON A SERVER 7 DAYS, AFTER 7 DAYS IT MAY BE OVERWRITTEN BY OTHER KEYS, DON'T PULL TIME, WAITING YOUR EMAIL
FREE DECRYPTION FOR PROOF
You can send us up to 1 file for free decryption. The total size of files must be less than 1Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)
When you make sure of decryption possibility transfer the money to our bitcoin wallet. As soon as we receive the money we will send you:
1. Decryption program.
2. Detailed instruction for decryption.
3. And individual keys for decrypting your files.
Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.

Log in to the account infected with the DrWeb virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.
If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.
Video showing how to remove ransomware virus using "Safe Mode with Command Prompt" and "System Restore":
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 DrWeb 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 DrWeb 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 DrWeb 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 DrWeb ransomware.
Note that Windows 10 Fall Creators Update includes "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default this feature automatically protects files stored in 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's more information on how to get this update and add 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.
