What is GarrantyDecrypt Ransomware

GarrantyDecrypt Ransomware has taken cemented position around the ransomware category and already deprived a fair amount of nerves and money of its victims. Like other ransomware, it infiltrates your computer by running encryption scripts that scan your device and therefore assign unbreakable cipher to each file. The first versions of this malware used .garrantydecrypt, .decryptgarranty, .protected, .NOSTRO, .odin, .cosanostra, .cammora, .metan, .spyhunter, .tater, .zorin extensions. However, encryption virus gets constantly modified and suffixes are changed too. Most recent extensions used by GarrantyDecrypt Ransomware are: .bigbosshorse, .heronpiston or .horsedeal. To illustrate, after encryption, 1.mp4 will be changed to 1.mp4.bigbosshorse or other abovementioned extensions. Unfortunately, any manual attempts to unlock the data are desperate. Once the encryption is finished, you will be presented with a ransom note created on desktop notifying that your data has been blocked. Ransomware recently has used #Decryption#.txt file for ransom note, and here is the message from this file:

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.
tell your unique ID -

Then ransomware developers offer you to buy a unique key that will ostensibly access the files. The payment has to be done only through Bitcoin. Also, the ransomware name indicates on swindler’s integrity that can be proven by decrypting one file that you can send via the attached e-mail. But do not dare rush and pay a fee because there is no guarantee that extortionists will keep their promises. Instead, the best solution would be to remove GarrantyDecrypt Ransomware from your computer and plausibly recover the lost data from backup.

How GarrantyDecrypt Ransomware infected your computer

Ransomware and other malicious software can be distributed through various infection channels like e-mail spam, trojans, and fake activation tools. E-mail spam, for instance, is used to distribute trojans that are disguised as attached files like Microsoft Office, PDF documents, executable files, and JavaScript files. Once clicked, the trojan will plant down on your device and cause so-called malware chains. And ransomware is the most common piece that contributes to the trojan’s list. GarrantyDecrypt Ransomware stops the following processes:

sqlwriter.exe, sqlbrowser.exe, sqlservr.exe, TNSLSNR.EXE, mysqld.exe, MsDtsSrvr.exe, sqlceip.exe, msmdsrv.exe, mpdwsvc.exe, fdlauncher.exe, Launchpad.exe, chrome.exe, oracle.exe, devenv.exe, PerfWatson2.exe, ServiceHub.Host, Node x86.exe, Node.exe, Microsoft VisualStudio, Web Host.exe, Lightshot.exe, netbeans64.exe, spnsrvnt.exe, sntlsrtsrvr.exe, w3wp.exe, TeamViewer_Service.exe, TeamViewer.exe, SecomSDK.exe, schedul2.exe, schedhlp.exe, adm_tray.exe, EXCEL.EXE, MSACCESS.EXE, OUTLOOK.EXE, POWERPNT.EXE, AnyDesk.exe, MicrosoftSqlServer, IntegrationServices, MasterServiceHost.exe, MicrosoftSqlServer, IntegrationServices, WorkerAgentServiceHost.exe

In addition to that, the virus removes shadow copies of files in Windows using the command: delete shadows /all /quiet. On top of that, virus developers tend to abuse fake cracking tools that are used to bypass paid software. Whilst promoting them as authentic activation tools, they hide sneaky trojans to infect your computer. In order to increase the circle of victims, deceivers use other channels of dissemination like Peer-to-Peer networks (e.g. torrents, eMule) and fake software updaters like Adobe Flash Player. These are the main ways that GarrantyDecrypt could attack your computer. To remove it, follow the guideline below.
