Protect ransomware removal instructions

What is Protect ransomware?

Protect (Hydra) encrypts files, changes their filenames and creates a ransom note. It renames all encrypted files by appending the ".protect" extension to their filenames. For example, it renames a file named "1.jpg" to "1.jpg.protect", "2.jpg" to "2.jpg.protect", and so on. Instructions on how to contact cyber criminals who designed this ransomware (and some other information) are provided in a text file named "===__________HOW DECRYPT MY FILES__________===.txt".

As explained in a ransom note (the ===__________HOW DECRYPT MY FILES__________===.txt" file), Protect ransomware encrypts files using asymmetric cryptography, AES-256 cryptographic algorithm. The only way to decrypt files is by using a decryption tool and private key that can be purchased from Protect's developers. In order to get instructions on how to purchase them victims have to contact these cyber criminals by writing them an email to and providing the "Network ID" which can be found in a ransom note. Victims are encouraged to contact Protect's developers in 48 hours because after that they will delete the provided email address and it will be impossible to contact them. Simply said, cyber criminals warn victims that after 48 hours they will not be able to purchase a decryption tool and recover their files. Typically, cyber criminals behind a particular ransomware are the only ones who have tools that can decrypt victim's files. However, they cannot be trusted. Quite often victims do not receive a decryption tool and/or key even if meet all their demands (contact them, pay a ransom). In most cases the only way to recover files for without having to pay a ransom and risking to get scammed is to restore them from a backup. Victims who uninstall ransomware from a computer do not make encrypted files accessible, they remain encrypted. However, by uninstalling it they prevent it from causing further encryptions.

Protect is quite similar to most other programs of this type. Here are some examples of other ransomware: Sekhmet, Taargo and .2020. In most cases they are designed to prevent victims from using their files by encrypting them and provide instructions on how to contact cyber criminals, pay a ransom and/or other details. Typically, two most common (and main) variables are price of a decryption and cryptographic algorithm (symmetric or asymmetric) that is used to lock (encrypt) data. Unfortunately, it is very common that victims cannot decrypt files without tools that only cyber who designed a particular ransomware have. It is possible only if their program is still a development state, is not finished, has some bugs, flaws, etc. Since it does not happen often, it is recommended to always have data backed up and store it on a remote server like Cloud and/or unplugged storage device.

How did ransomware infect my computer?

One of the most popular ways to proliferate ransomware and other malware by sending emails that contain malicious attachments or website links that are designed to download malicious files. In most cases cyber criminals send emails that contain some alicious Microsoft Office, PDF document, executable file like .exe, archive file like ZIP, RAR, or JavaScript file. Malware gets installed when recipients open (execute) a malicious file/attachment. Another way to spread malicious software is by deceiving users into installing some Trojan. It is a type of malicious software that can be designed to cause chain infections. In other words, to install more malicious programs. Fake software updaters can be used to distribute malware too. If used, they infect system by installing malicious software instead of updating installed software, or by exploiting bugs, flaws of outdated software. Untrustworthy software download channels like freeware download websites, free file hosting pages, Peer-to-Peer networks (e.g., torrents, eMule), various third party downloaders, installers are often used as tools to host, upload malicious files. Users who download software and files through the risk to download some malicious file that, if opened/executed would cause installation of high-risk malware. One more way to unintentionally install ransomware other type of malware is by using unofficial activation ('cracking') tools to activate licensed programs. Tools of this type supposed to bypass activations, nevertheless, quite often they are designed tp cause installation of some malicious software.

How to protect yourself from ransomware infections?

Attachments and/or website links in irrelevant emails should not be trusted (opened). Especially if such emails are received from unknown, suspicious addresses. it is worthwhile to mention that cyber criminals tend to disguise their emails as official, important, and so on. All software and files should be downloaded from official websites. It is not safe to use any other channels (like the ones that are mentioned in the previous paragraph) for that. Also, installed software must be updated and activated (if necessary) through tools or functions that are designed by official developers. Third party, unofficial tools can be designed to install malware. Besides, it is not legal to activate any licensed software with them. One more way to keep computers safe is to regularly scan them for threats with a reputable antivirus or anti-spyware suite and always remove detected threats as soon as possible. If your computer is already infected with Protect, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

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 Protect 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 Protect 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 Protect 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 Protect, 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 Protect 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.

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.
