.shadow ransomware removal instructions
What is .shadow?
.shadow is a computer infection categorized as ransomware and a new variant of the STOP ransomware virus. Like many other ransomware-type infections, .shadow is designed to encrypt data stored on victims computers and demand ransom payments. All locked files are renamed by adding the ".shadow" extension. For example, "1.jpg" becomes "1.jpg.shadow". A ransom demand message is presented in a text file named "!readme.txt".
According to the ransom demand message in "!readme.txt", all files are encrypted, and to unlock them, victims are encouraged to contact cyber criminals via the firstname.lastname@example.org or email@example.com email address. Ransomware developers will then provide the cost of a decryption tool supplied to victims when the ransom is paid. They also offer free decryption of one file (that does not contain valuable information) as 'proof' that they can be trusted and are capable of file decryption. Furthermore, .shadow developers offer a discount of 50% for victims who make contact within 72 hours. They urge people not to use any tools other than theirs for data decryption, since, according to them, this will cause permanent data loss. Unfortunately, .shadow developers are probably the only people who can provide victims with a decryption tool. Generally, these criminals use algorithms that generate unique decryption keys that are stored on remote servers (controlled only by them). This makes data decryption without involvement of cyber criminals (ransomware developers) impossible. Note, however, that these people usually ignore victims even if their ransom demands are met. Therefore, we recommend that you do not contact them or pay any ransoms. The best (and only) solution in these cases is to use an existing data backup and restore everything from there.

.shadow is similar to many other viruses of this type. Other examples are Bkpx, Dablio, and GandCrab 5.0.9. Most ransomware-type infections encrypt data and keep it in that state until a ransom is paid, or decryption tool or key is purchased. The most common differences are cost of decryption and cryptography algorithm used to lock/encrypt files. These infections are usually impossible to crack, unless they are not fully developed or have bugs/flaws. Therefore, maintain regular backups and store them on unplugged storage devices or remote servers (this will prevent cyber criminals encrypting them with other regular data).
How did ransomware infect my computer?
It is difficult to ascertain exact which method cyber criminals use to proliferate this ransomware, however, most use similar or identical tactics: spam email campaigns, trojans, fake software updating tools, or untrustworthy software download sources. Spam campaigns distribute emails that contain malicious attachments that, once opened (executed), infect computers with a specific virus. Trojans are malicious programs used to infect computers by causing chain infections. In summary, the presence of an installed trojan will probably cause other infections. Fake software update tools exploit outdated software bugs, flaws, etc. or download and install high-risk viruses rather than the updates. Untrustworthy software download sources are include peer-to-peer networks, third party downloaders, freeware download, and file hosting websites. Cyber criminals use these sources to present their viruses as legitimate executables (or other) files. By downloading and installing them, many users are tricked into causing computer infections.
|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 .shadow virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
Download software using official and trustworthy websites, rather than peer-to-peer networks, third party downloaders, and other untrustworthy sources. Note that rogue set-ups (downloaded using untrustworthy sources) are used to proliferate unwanted apps or spread infections. Avoid downloading and opening attachments (and web links) in emails received from unknown, suspicious email addresses, or if the emails are irrelevant. Update your software using implemented functions or tools provided by official software developers only. Have a reputable anti-virus or anti-spyware software installed on your computer and keep it enabled. These tools can prevent systems infection by viruses. If your computer is already infected with .shadow, 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 .shadow 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 .shadow 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 .shadow 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 .shadow 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.
