Boom ransomware removal instructions
What is Boom?
Boom is a ransomware-type computer infection that was discovered by MalwareHunterTeam. Like most programs of this type, it is designed to encrypt data and make ransom demands. In this case, it displays ransom messages on modified desktop wallpaper, and within a text file ("HOW TO DECRYPT FILES.txt") and pop-up window. There are several variants of this ransomware (the corresponding text file, pop-up window, and desktop wallpaper designs might differ) depending on the Boom version. All encrypted files are renamed by adding the ".Boom" extension to each file. For example, "1.jpg" becomes "1.jpg.Boom".
Several minutes after encryption, this virus restarts the computer and then displays ransom-demand messages. Ransom messages generated by Boom inform victims that all data is encrypted and, to retrieve their files, users must enter a PIN number that can be found in the pop-up window. At time of research, clicking this button led to a broken Facebook page link that cannot be opened. Cyber criminals who use Facebook as a contact form are often amateurs - a broken link to a page that cannot be opened obviously suggests that it is impossible to contact them. Furthermore, there are no other ways to contact them (no email address or other means is provided). In any case, cyber criminals should never be trusted: often they ignore victims even if ransoms are paid (i.e. if decryption tools or keys are purchased). Unfortunately, most ransomware developers use cryptography algorithms that generate unique keys. Therefore, only specific keys/tools can be used to decrypt files encrypted by ransomware programs. Cyber criminals store these keys on remote severs controlled only by them. Therefore, it is generally impossible to decrypt files without the involvement of ransomware developers (not recommended). Boom developers urge victims not to restart their computers more than 10 times, since this will apparently cause permanent data loss. There is no tool available to decrypt files free of charge and no way to contact these cyber criminals. Therefore, we recommend that you use an existing data backup and restore your files from there.

There are many ransomware-type viruses (such as Phobos, Seon, Nostro, and so on) available online, most of which are quite similar: these programs are designed to encrypt data (block access to files) and keep it in this state unless the ransom demands are met. Typically, the only differences are the cryptography algorithm used for encryption and the cost (ransom) of a decryption tool/key. Unfortunately, most of these viruses are impossible to 'crack' - only the developers can provide tools or keys required for decryption. Decryption without their involvement might only be possible if the infection is not fully-developed or contains bugs/flaws. For these reasons, we recommend that you maintain regular backups and store them on remote servers or unplugged storage devices.
How did ransomware infect my computer?
In most cases, ransomware-type viruses such as Boom are proliferated through spam email campaigns, trojans, fake software updaters, and various untrustworthy/unofficial software download sources. Spam campaigns proliferate viruses by sending emails that contain malicious attachments (Microsoft Office document, PDF, archive files, executables, and so on) or web links that lead to such files. Once opened, these attachments infect computers by downloading and installing viruses. Trojans, on the other hand, are malicious programs that proliferate other viruses. These malicious programs cause chain infections when installed. Untrustworthy software download tools such as P2P (peer-to-peer) networks (eMule, torrents, etc.), freeware download websites, and free file hosting websites present malicious software as legitimate. Using these channels, cyber criminals often successfully trick people into downloading and installing viruses (rather than regular software). Fake software updaters exploit bugs and flaws of outdated software or download and install malicious programs rather than the promised software updates/fixes.
|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 Boom virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
To keep computers safe from infection by Boom (or other high-risk viruses), be cautious while browsing the web, downloading, installing and updating software. Web links and attachments presented in emails received from unknown and suspicious email addresses should not be opened (or clicked). Download software using official and trustworthy sources, and not third party downloaders, unofficial websites, peer-to-peer networks, and so on. The aforementioned tools often proliferate rogue apps that can provoke various computer infections. Keep software updated, however, this should be done using implemented functions or tools provided by official developers only. Having reputable anti-virus/anti-spyware software installed is also very effective in avoiding computer infections: these tools can detect and eliminate threats (malicious programs, etc.) before they damage the system. If your computer is already infected with Boom, 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 Boom 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 Boom 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 Boom 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 Boom 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.
