GarrantyDecrypt is a dangerous ransomware that encrypts your files using RSA algorithm

GarrantyDecrypt file extension virus
GarrantyDecrypt ransomware seeks to get victims' money by making them useless and then offering the special key for their decryption.
 

GarrantyDecrypt ransomware is a dangerous cyber threat that uses RSA-4096 algorithm to make your data useless. The process is followed by adding the file extension called .garrantydecrypt to all encoded files, including photos, documents, music files, and even archives or servers. It seems that the attack starts with a silent infiltration and the removal of additional malware. According to cybersecurity analyst Demonslay, this virus firstly terminates other intruders on the system and then starts the encryption process.[1] However, the victim notices ransomware activity only after the previously-mentioned extension appears next to the files' names. The ransomware also places the #RECOVERY_FILES#.txt file that contains a message from virus developers.

As usual for the cyber threats hailing from this category, GarrantyDecrypt works silently on the system until the victim notices particular changes. Malware focuses on the data encryption process and seeks to make every user's file or its copy unavailable for the use. That's because cybercriminals who are working behind the malicious intruder seek to earn the money by making their victims to pay the requested ransom fee. However, no matter how low the ransom amount is you shouldn't pay for them. 

When a virus infiltrates the system, it disables any malware that might already exist on the system and starts encrypting files. GarrantyDecrypt ransomware uses RSA-348 algorithm first and then opts for RSA-4096 encryption method to make your data useless. The encryption process is fairly quick[2], and you cannot notice the activity in the background.

After the successful encryption, the malware creates a ransom note called #RECOVERY_FILES#.txt which reads the following: 

All your files have been ENCRYPTED
Do you really want to restore your files?
Write to our email – garrantydecrypt@airmail.cc
and tell us your unique ID

The hackers behind GarrantyDecrypt ransomware might encourage you to pay the ransom if you want to get your data back. In exchange for your payment, they typically promise to send their victims a special code which is saved on their remote servers and can't be guessed. However, you need to avoid contacting these people because it may lead to permanent data or money loss. 

At first, focus on GarrantyDecrypt removal to make sure that the system is clear from malware. Additionally, restore your files from an external drive, cloud or a simple USB stick. If you don't have backups, try our tips given at the end of this article. Researchers[3] note that it is highly recommended to create a few different versions (three at least) of the file to keep it safe. Store your data on external devices and a cloud service remotely. 

You can remove GarrantyDecrypt ransomware using reputable anti-malware tools like Reimage. Automatic virus elimination is the most helpful in this case because any additional viruses hiding on your computer can be removed during the full system scan. Follow the actions your anti-malware tool suggests after the full system scan.

Malicious file attachments spread ransomware payload directly on your device

In the cyber world, the most common method used to spread malicious programs is spam. When you get a questionable email with an attached document, pay more attention because it is possible that safe-looking MS Word or Excel files contain malicious macros or spread malware directly on your device.

Any email with the subject line “Invoice” or “Order information” sent from the service or company you do not use can be malicious and spread various threats on the system of your computer. Make sure to scan the file before downloading and opening on the system. You can also delete spam email box more frequently. 

Unfortunately, malicious actors disguise their products behind known names, so be aware that companies do not send emails with typos, grammar mistakes and financial information documents attached for ransom people. If you get PayPal or FedEx email when you do not use the service – delete it. 

Proceed with GarrantyDecrypt elimination as soon as possible 

When you find your files encrypted by the cryptovirus, don't waste your time because every minute counts as ransomware can try to encrypt more files on your computer. Better scan your system by using reputable anti-malware or antivirus program to remove GarrantyDecrypt or any additional malware from your computer. Use Reimage, Malwarebytes MalwarebytesCombo Cleaner or Plumbytes Anti-MalwareMalwarebytes Malwarebytes and make sure to double check if the system is clear before plugging in any external devices.

GarrantyDecrypt ransomware removal needs to be done before you start recovering your locked files. The thorough system scan is nothing but beneficial for the system because, during the process, various PUPs and additional intruders will be removed from the system.

If you have files' backups, you can restore encrypted files with safe ones after GarrantyDecrypt ransomware termination. However, if you do not have the habit of backing your data, try our data recovery methods listed below.
