BigBossRoss ransomware removal instructions
What is BigBossRoss?
BigBossRoss is a new variant of Garrantydecrypt ransomware. It is designed to prevent its victims from accessing their files by encrypting them. In order to decrypt files victims are forced to purchase a decryption tool from cyber criminals who designed this ransomware. BigBossRoss appends the ".bigbossross" extension to filenames of all encrypted files, for example, it renames "1.jpg" to "1.jpg.bigbossross", and so forth. Also, it creates the "#Decryption#.txt" which contains instructions on how to contact developers of the BigBossRoss ransomware.
These cyber criminals can be contacted via email (email@example.com) or Jabber (firstname.lastname@example.org). The "#Decryption#.txt" text file contains mostly instructions on how to install the Jabber application. Typically, cyber criminals behind ransomware-type programs are the only ones who can help their victims to decrypt encrypted files. In other words, they are the only ones who have tools that can decrypt files encrypted by their ransomware. Another problem is that most cyber criminals cannot be trusted, quite often they do not provide decryption software (and/or key) even after receiving a ransom/payment. Typically, the only way to avoid being scammed and recover files without using decryption tools that can be purchased from cyber criminals is to restore them from an existing data backup. Besides, removing ransomware from the system only prevents it from causing further encryptions, all encrypted files remain encrypted.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
Most ransomware-type programs are designed to operate very similarly: they lock (encrypt) data and create and/or display a ransom note that contains instructions on how to contact cyber criminals and other details. The two main differences usually are price of a decryption software and/or key and cryptographic algorithm (symmetric or asymmetric) that is used to encrypt data. Here are some examples of other ransomware: Mapo, Bitx and ROGER. Unfortunately, in most cases it is impossible to decrypt files encrypted by ransomware without the tools that only developers of a particular ransomware can provide. It is possible to recover files without using their tools only if ransomware is not completed (contains bugs, flaws, etc.). That is why it is important to always have data backed up and store it on a remote server or unplugged storage device.

|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 BigBossRoss virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
Attachments or web links that are presented in irrelevant emails, especially if those emails are received from unknown, suspicious addresses should not be opened. Software should be downloaded only via direct download links and official pages. Other sources that we mentioned in the paragraph above should not be trusted. Furthermore, installed programs must be updated via tools or implemented functions that are designed by official developers, the same applies to activation of programs that require to be activated. Besides, 'cracking' tools (unofficial activators) are not legal and often cause installation of malware. And finally, it is recommended to have a reputable antivirus or anti-spyware suite on the operating system installed and scan it regularly. If your computer is already infected with BigBossRoss, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

If you don't understand our Pidgin client installation instructions, you can find many installation tutorials on youtube - hxxps://www.youtube.com/results?search_query=pidgin+jabber+install
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.

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 BigBossRoss 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 BigBossRoss 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 BigBossRoss 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 BigBossRoss 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, and 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.
