Garrantydecrypt ransomware removal instructions
What is Garrantydecrypt?
Garrantydecrypt is another ransomware-type virus discovered by Michael Gillespie. After successfully infiltrating the system, Garrantydecrypt encrypts most stored data, thereby making it unusable. In addition, Garrantydecrypt adds the ".garrantydecrypt" appendix to the name of each compromised file. For example, "sample.jpg" is renamed to "sample.jpg.garrantydecrypt". Updated variants of this ransomware use ".decryptgarranty" extension for encrypted files. Once encryption is complete, Garrantydecrypt generates a text file named "#RECOVERY_FILES#.txt" and places a copy on the victim's desktop.
The new text file contains a very short message stating that data is encrypted and that users must contact Garrantydecrypt's developers if they want to restore it. No additional information regarding the encryption is provided and thus it is currently unknown whether Garrantydecrypt uses symmetric or asymmetric cryptography. In any case, decryption requires a unique key generated individually for each victim. All keys are stored on a remote server controlled by cyber criminals. Therefore, after contacting these people, users are asked to pay ransoms in exchange for release of their keys. In most cases, criminals demand $500-1500 in Bitcoins, Monero, DASH, or another cryptocurrency. Note that cyber criminals cannot be trusted. Research shows that these people often ignore victims, once payments are submitted. Therefore, ignore all requests to contact these people and do not submit payments. Unfortunately, there are no tools capable of cracking Garrantydecrypt encryption and restoring data free of charge. The only solution is to restore everything from a backup.

There are dozens of ransomware-type viruses that share similarities with Garrantydecrypt including GandCrab 5.0.2, Koolova, Dharma-Btc, and NOT_OPEN LOCKER - the list goes on. Although these viruses are developed by different cyber criminals, their behavior is identical - all encrypt data and make ransom demands. In most cases, viruses such as Garrantydecrypt have just two major differences: cost of decryption and type of cryptography used. Most employ algorithms designed to generate unique decryption keys. Therefore, unless the virus is not fully developed or has certain bugs/flaws (the key is hard-coded, stored locally, etc.), restoring data manually without involvement of developers (contacting these people is not recommended) is impossible. Ransomware-type viruses are one of the main reasons why you should maintain regular data backups, however, it is important to store them on a remote server (e.g., Cloud) or an unplugged storage device. If not, backups are encrypted with regular data.
How did ransomware infect my computer?
Ransomware-type viruses are often distributed using trojans, spam email campaigns, peer-to-peer (P2P) networks, third party software download sources, and fake software update tools. Trojans cause various chain infections - one virus distributes another. Spam campaigns proliferate malicious attachments that, once opened, infiltrate viruses into the system. P2P networks (torrents, eMule, etc.) and other unofficial software download sources (free file hosting websites, freeware download websites, etc.) present malicious executables as legitimate software, often tricking users into downloading and installing viruses. Fake software updaters infect computers by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than promised updates.
How to protect yourself from ransomware infections?
To prevent this situation, be very cautious when browsing the internet and downloading, installing, and updating software. Carefully analyze all steps of the download/installation processes. Think twice before opening email attachments. If the file is irrelevant/unexpected or the sender seem suspicious, do not open it. Furthermore, download your programs from official sources only and avoid using third party downloaders/installers, since developers monetize them by promoting rogue software. The same rule applies to software updates. It is important to keep installed programs up-to-date, however, this should be achieved through implemented functions or tools provided by the official developer only. Having a reputable anti-virus/anti-spyware suite installed and running is also paramount, since these tools can detect and eliminate viruses before they do any damage. If your computer is already infected with Garrantydecrypt, 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 Garrantydecrypt 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 Garrantydecrypt 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 Garrantydecrypt 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 Garrantydecrypt 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.
