Gero virus Removal Guide

What is Gero ransomware?

Gero cryptovirus is the ransomware that belongs to a DJVU virus family but has the updated encryption method

Gero ransomwareGero ransomware is a virus that focuses on changing users data, so the ransom can be demanded. Gero ransomware is one of almost 200 variants in the same STOP virus family of extortion-based malware. This is the recent version that came out with different encryption than other versions. This change means that versions of the threat cannot be decrypted with a previous STOP decryption tool that was helpful for the biggest part of the older variants. There was a chance to decrypt files when offline keys got used for encoding data. Now the same tools are useless for the newest variants, although older threats can be decrypted.

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

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 ReimageIntego 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:

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. Gero ransomware virusGero ransomware cryptovirus is the threat that is developed by cybercriminals. The DJVU family is one of the more active at the time.

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 ReimageIntego 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. Gero files virusGero ransomware is the threat that encrypts files on the system and marks then using .gero file appendix.

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 ReimageIntego. 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.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Gero from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

If your files are encrypted by Gero, you can use several methods to restore them:

Data Recovery Pro can be one of the many options suitable for the file restoring after the ransomware attack

You may need an alternate method for file restoring when backups are not up to date. Data Recovery Pro is the program for that

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Gero ransomware;
  • Restore them.

Gero ransomware encrypts files, try to recover them with Windows Previous Versions

When System Restore feature gets enabled, you can try Windows Previous Versions for data recovery

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer is capable of restoring files after Gero ransomware attack

ShadowExplorer works when ransomware leaves Shadow Volume Copies untouched

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Decryption is not possible for Gero ransomware affected files

However, many researchers work on creating such tools, so check occassionaly

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Gero and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

 

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
