BlackRouter ransomware removal instructions

What is BlackRouter?

Discovered by Petrovic, BlackRouter is categorized as a ransomware-type malicious program. This virus (like most viruses of this type) blocks access to files (encrypts data) and displays ransom-demand messages in a pop-up window and a text tile called "ReadME-BlackRouter". BlackRouter renames all encrypted files by changing/adding a new extension. For example, file named "1.jpg" is renamed to "1.jpg.BlackRouter".

The "ReadME-BlackRouter" ransom message states that data has been encrypted and an email address ( should be used to contact cyber criminals to unlock (decrypt) the files. BlackRouter also displays a pop-up window with a form to make a transaction (pay the ransom). According to these cyber criminals, they have encrypted all data and completing the payment form is the only way to decrypt it. The cost of decryption is $300, however, a countdown timer is displayed with a deadline. Once this expires, the cost of decryption doubles. To perform the transaction (and make a request for a decryption key), users must transfer $100 into one cryptocurrency wallet and $200 into another. It is not known which cryptography algorithm BlackRouter's developers use for data encryption, however, most cyber criminals use algorithms (symmetric or asymmetric) that generate unique keys. Ransomware developers store the keys on remote servers that can be accessed only by them. Unfortunately, most encryption algorithms are impossible to 'crack', and thus decryption without the involvement of ransomware developers (not recommended) is impossible. Furthermore, there are no tools capable of decrypting BlackRouter encryption free of charge. Do not contact these or any other ransomware developers, or pay any money - most cyber criminals ignore victims even if the ransom demands are met (i.e. the sum is transferred). The best option in these cases is to use a backup created earlier and restore files from there.

There are many ransomware-type malicious programs on the internet, all of which are quite similar to BlackRouter. Examples include Boom, Vulston, Phobos, and many others. Typically, computer infections of this type share two similarities: they encrypt data and attempt to blackmail victims by demanding ransom payments. Common differences are cryptography algorithm used to encrypt data and the cost of a particular decryption tool (or key). In most cases, it is impossible to decrypt data without the help of the ransomware developers, unless ransomware is not fully developed (is still in development) or contains bug/flaws. Therefore, create regular data backups stored on unplugged storage devices or remote servers, otherwise, cyber criminals are able to encrypt backups with the remaining data.

How did ransomware infect my computer?

Systems become infected by BlackRouter ransomware through spam email campaigns, fake software updaters/updating tools, trojans, and unofficial/untrustworthy software download sources. Cyber criminals infect computers through spam campaigns by attaching malicious (infected) files. Fake software update tools usually infect systems by exploiting bugs/flaws of outdated software or by downloading malicious programs rather than the promised updates. Trojans are malicious programs that cause chain infections: they proliferate other computer infections (including ransomware-type viruses). Unofficial software download sources such as websites offering to download freeware (free software), free file hosting websites, Peer-to-Peer (P2P) networks such as torrents, eMule and other such tools, present various untrustworthy executables as legitimate applications. Using these channels, cyber criminals often successfully trick users into installing malicious programs.

Threat Summary:
NameBlackRouter virus
Threat TypeRansomware, Crypto Virus, Files locker
SymptomsCan'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 methodsInfected email attachments (macros), torrent websites, malicious ads.
DamageAll 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 BlackRouter virus our malware researchers recommend scanning your computer with Spyhunter.

How to protect yourself from ransomware infections?

Browse the web and download, install, and update software with care. Do not open attachments (or web links) presented in irrelevant emails that are sent from unknown, suspicious addresses. Keep your software updated, but use implemented, official tools that are provided by software developers. Download software using official and trustworthy websites (or other official sources) and direct links. Avoid using third party software downloaders/downloading tools or unofficial, suspicious websites. Have trustworthy (reputable) anti-spyware or anti-virus software installed and keep it enabled and updated at all times. These tools can prevent computer infection by viruses. If your computer is already infected with BlackRouter, 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.

Boot your computer in Safe Mode with Command Prompt

2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.

4. In the opened window, click "Next".

restore system files and settings

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 BlackRouter ransomware virus infiltrating your PC).

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining BlackRouter 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 BlackRouter 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.

Restoring files encrypted by CryptoDefense

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 regain control of the files encrypted by BlackRouter, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

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 BlackRouter 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.

Controll Folder Access

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:
