Gero cryptovirus is the ransomware that belongs to a DJVU virus family but has the updated encryption method
The only solution for this threat – total virus termination since this Djvu ransomware strain cannot be eliminated using other methods. Then, you can try to employ other tools and features that your device has, or rely on paid services offered by cybersecurity researchers. Unfortunately, this is a pricy pleasure, so keep those encrypted files and wait for the newer version of decryption tool that could work for Gero files virus.
When Gero ransomware virus infects the system, it starts the encryption and file marking process immediately. Once that is done, files get .gero file markers and cannot be opened anymore. As _readme.txt – a ransom note states, the victim needs to pay as soon as possible to get at least an opportunity to get their data back. However, we never recommend paying since it can lead to more damage than positive results.[1] You should check the article to find a more reliable method of decryption or data recovery.
| Name | Gero ransomware |
|---|---|
| Type | Cryptovirus that encrypts files with the aim to get profit from people |
| File extension | .gero is the appendix that marks every encrypted document, photo, video file or archive |
| contact Email addresses | gorentos@bitmessage.ch, gerentoshelp@firemail.cc |
| Family | DJVU/STOP virus |
| Additional danger | Virus leaves behind a software module that steal personal data, installs direct AZORult malware payload, modifies host files and can steal data stored on the machine or web browser |
| Ransom amount | $980 is the initial demand, but criminals offer to lower the price to $490. This is the method that should fake the trust between virus developers and victims |
| Ransom note | _readme.txt is the file that delivers ransom demanding message with all the payment instructions and contact details |
| Alters files in directories |
|
| Decryptable? | This version came out with different encryption method and cannot be decrypted with STOP decrypter. However, there are some other options for the particular version that uses offline keys for encoding. (Direct link to decryptor additional instructions can be found here) |
| Elimination | Install anti-malware and remove Gero ransomware. You need a professional anti-malware program to get rid of the malware, as manual termination is hardly possible for regular users |
| recovery | If you suffer from system slowdowns, crashes and other unwanted behaviors after malware infection, use FortectIntego to repair it |
Gero ransomware is the threat that affects your photos, videos, documents, and even archives because it alters common types of data found on the machine. This encryption process starts immediately after the initial system infiltration because the virus is developed to scan the device quickly.
Gero ransomware delivers the following message for each victim, where criminals explain all the possibilities for the person affected:
ATTENTION!
Don’t worry, you can return all your files!
All your files like photos, databases, documents and other important are encrypted with strongest encryption and unique key.
The only method of recovering files is to purchase decrypt tool and unique key for you.

The typical ransom demand message is not changed since the beginning of Djvu ransomware attacks, so the message is the same for other variants on the same family as Gero ransomware. The principle of this threat is the same – encrypting personal files and offer to decrypt data for a hefty payment in cryptocurrency.
Although the message from Gero ransomware developers seem calm and may create trust, you need to remember that malicious actors who create such treats are self-centered criminals and have no mercy form their victims. Sometimes cryptovirus may be designed to restrain from third-world countries. This is the only merciful behavior you can expect from malicious threat creators. 
A deeper look into Gero ransomware decryption options
Gero file-locking virus is 156th version in the family that started its malicious attacks back in November 2018. However, up until this .gero version, all the files were decryptable with STOP virus decryption tool. In this case, you need to get rid of all the parts of the virus and then rely on data recovery tools or file backups on external devices.
The encryption method got altered and never variants rely on a proper asymmetric algorithm that is not relying on offline keys that got used before. However, when offline keys are used, other decryption possibilities can work. When personal IDs end in t1 it is possible to recover files using the tool listed here.
However, you still need to get your files back even though decryption is not possible. You cannot attempt any data restoring until you perform Gero ransomware removal on the machine. Get anti-malware tool and then run the full system scan to eliminate all components of the ransomware. We also recommend running a scan with FortectIntego to eliminate virus damage.
DR.Web researcher team also offers the service called Rescue Pack that can decrypt various file formats. However, not all of them get recovered and this service costs 150 euro per victim. You should consider trying this if you are desperate to get encrypted files back.
Since Gero ransomware decryption is a sensitive topic, you should save those encoded files and wait for the particular software capable of recovering those files. Try to check for tools here from time to time:

This is STOP/Djvu ransomware version, but the more recent versions .gero and .hese came out not decryptable. So you need to remove Gero ransomware and then attempt to restore encrypted files using data backups. Do not contact the criminals yourself, as they may attempt to take advantage of you or continue to extort you.
Djvu cryptovirus family is known as the one that installs the Azorult trojan besides the encryption process.[2] This malware allows stealing passwords from the victim. So it is crucial to change all passwords, as experts[3] note you need to do so for your computer and online services. However, do so when your computer is clean, and Gero ransomware is not running in the background.
Infected files deliver the direct malicious script
Ransomware is one of the many threats that distributes with the help of other malware and also can spread threats during its own infiltration. This threat can come alongside trojans, worms, or malware, but the main spreading technique for all of these cyber intruders remain the same – infected email attachments filled with macro viruses.
Criminals spam out emails with forged subject lines, sender information and trick people into believing that the notification is delivered from the legitimate company like FedEx, DHL, and so on. Unfortunately, people fell for such tricks and opens those emails. File attachments when opened delivers malicious scripts and leads to ransomware infections.
Avoid infections by:
- deleting received emails if not expected;
- pay close attention to the spam email box and its contents;
- avoid downloading and opening files attached to emails;
- check for typos and hyperlinks before opening anything from the email.
Additional facts about the particular virus family include certain methods of spreading. When the newest versions got released, many users complained about the infection online, searching for particular decryption options. Also, those victims revealed that main vector used by criminals includes software cracks and details like serial game numbers, licensed keys for legitimate OSs and other cheats. Avoid such illegal activities, since these are also used to deliver malware.
Eliminate Gero ransomware virus with robust anti-malware tools
You need to rely on professional tools that are required for Gero ransomware removal because this threat is more than dangerous when it can install AZORult malware and other info-stealers on the machine. The encryption becomes less of a damaging process when users data becomes affected, stole, or even leaked. Since the virus loads other files and modifies crucial places of the machine, locate to C:\Windows\System32\drivers\etc\ and find modified host file to delete it completely.
You should remove Gero ransomware, and then clean the virus damage with FortectIntego. If you have reliable backups, you can use those to replace encoded files, or get a data restoring software. Also, you may have an advantage in all these processes if you go for the methods listed below.
