BI_D ransomware removal instructions
What is BI_D?
First discovered by malware security researcher, Michael Gillespie, BI_D is a new variant of high-risk ransomware called LockCrypt. Immediately after infiltration, BI_D encrypts most stored files (thereby making them unusable) and appends filenames with the " [ id-[victim's_ID].BI_D" extension. For example, "sample.jpg" might be renamed to a filename such as "sample.jpg id-iK+mYICIYCIU.BI_D". Following successful encryption, BI_D creates a text file ("How to Restore Files.txt") and places a copy in every existing folder.
As usual, the new text file contains a message stating that data is encrypted and that victims must pay for decryption. To do this, they must contact BI_D's developers via an email address provided. They are also permitted to attach up to three selected files, which are decrypted and returned as 'proof' that restoring data is possible. No additional information is provided. Therefore, it is currently unknown whether BI_D uses symmetric or asymmetric cryptography. In any case, a unique key (generated individually for each victim) is necessary to restore data. All keys are stored on a remote server controlled by BI_D's developers. This gives cyber criminals a significant advantage and an opportunity to blackmail victims. To receive their keys, victims must transfer a specific sum in the Bitcoin cryptocurrency to the developer's wallet. The cost is not specified - developers provide these details via email, however, in most cases they demand $500-1500 in Bitcoins, Monero, or another cryptocurrency. Regardless of the cost, do not pay. Research shows that many victims are ignored after submitting payments. Strictly speaking, paying gives no positive result and you will be scammed. Therefore, we strongly advise you to ignore all requests to contact these people or submit any payments. There are currently no tools capable of restoring data encrypted by BI_D free of charge and you can only restore everything from a backup.

BI_D shares many similarities with Insta, CRYBrazil, DiskDoctor, OpsVenezuela, and dozens of other ransomware-type viruses. Research shows that all have identical behavior (they encrypt data and demand ransom payments) even though they are developed by different parties. There are often just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Unfortunately, most ransomware viruses employ algorithms that generate unique decryption keys (for example, RSA, AES, and similar). Therefore, unless the malware is still in development or there is a bug/flaw (e.g., the key is hard-coded, stored locally, etc.), restoring data without involvement of developers (contacting these people is not recommended) is impossible. This is one of the main reasons why you should maintain regular data backups, however, remember to store them on an unplugged storage device (e.g., external hard drive, Flash drive or similar) or remote server (e.g., Cloud). If not, 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 BI_D virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
To prevent ransomware infections, pay close attention when browsing the Internet and downloading/installing/updating software. Think twice before opening email attachments. If files seem irrelevant or have been received from a suspicious email address, do not open them and delete the email immediately. You are strongly advised to download your software from official sources only (using direct download links), rather than third party download/installation tools. These tools often include rogue software, and thus should never be used. The same rule should be followed when updating software. Keeping installed applications up-to-date is also paramount, but use implemented update functions or tools provided by the official developer only. Having a reputable anti-virus/anti-spyware suite installed and running is paramount. The key to computer safety is caution.

Instant automatic removal of BI_D virus:
Manual threat removal might be a lengthy and complicated process that requires advanced computer skills. Spyhunter is a professional automatic malware removal tool that is recommended to get rid of BI_D virus. Download it by clicking the button below:
- What is BI_D?
- STEP 1. BI_D virus removal using safe mode with networking.
- STEP 2. BI_D ransomware removal using System Restore.
Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

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 BI_D 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 BI_D 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 BI_D 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 BI_D 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.
