Zida ransomware (Virus Removal Guide) - Decryption Steps Included

Zida virus Removal Guide

What is Zida ransomware?

Zida ransomware – a threat that comes from a notorious file-locking malware family and cannot be decrypted, in most cases

Zida ransomwareZida ransomware - the threat that locks your files and makes them useless to have a reason for blackmail. Zida ransomware – cryptovirus that delivers the main ransom-demanding note in the _readme.txt file. This particular message notifies you about the encoding procedure and encourages you to pay $980 in Bitcoin for the criminals. This is typically a procedure that follows the file locking – the main purpose if the infection like this. Unfortunately, ransom payments get you nowhere, and files, in most cases, remain locked even when the victim sends the amount of cryptocurrency to attackers.

The family that this threat belongs to previously was decryptable, but this is the latest version that cannot be decrypted using a tool because researchers haven't released a proper software for that and cryptovirus developers still use the powerful code, online IDs that are unique for each new device encrypted during the attack. Many people[1] claim that the threat appeared out of nowhere and that Zida files virus is extremely persistent and cannot be removed easily.

The first thing that we should note and warn about is that .Zida file virus is not decryptable. Also, pay attention to the fact that those encrypted files cannot be easily recovered during the malware elimination. Data restoring, malware elimination, system repair are all separate processes. Even when you hear about the shady Zorab ransomware that is disguised as a decryption tool.[2]

Name Zida ransomware
Type Cryptovirus[3]
Family Djvu ransomware family that comes from STOP virus
File marker .zida is the indicational file extension that gets added to the end of your original file name, so you know that locked files are encrypted
Distribution The malicious payload file gets loaded on the machine from pirated software packages or malicious email attachments and trigger the file-locking right away
Ransom note _readme.txt – the file that contains all the details about encryption and the payment, contact information
Issues The ransomware can easily trigger other processes in the background, run malware that steals information and damage functions, disable programs, install other tools
Elimination Zida ransomware removal process requires users attention and professional anti-malware tools because other malicious files cannot be found manually
Repair You need to terminate the damage that this virus causes because any traces left in system folders and registry, for example, can still affect the machine and possibly trigger more damage. Run FortectIntego to find and repair affected data automatically

Due to the usage of online keys, victims of Zida ransomware virus need to wait for the tool that can be developed later on or stop thinking about the decryption entirely. Online IDs mean that malware connects to the command and control server while encrypting those files, so they are unique and not easy to identity. If the ID in the ransom note file and with t1, you might be the lucky one that suffered encryption with the usage of offline keys. If so, you may have other options.

If not, the only solution for these locked files is your data backed up in external databases, on cloud services. You need to terminate .zida virus when you notice these file alterations, receive the _readme.txt file, and find your device not useable. You need to make sure that the virus is fully removed when you rely on third-party options, so the machine is virus-clean before you replace affected files with safe copies.

You can remove Zida ransomware with an anti-malware tool that is designed to detect and indicate, clear off those malicious files, programs, and leave the machine free of threats. You need to base the selection of a particular AV engine on the detection[4] rate that shows which tools have the database where this blackmail-based threat is included.

When you find the program that is trustworthy and decide to eliminate Zida ransomware, you need to run the full system scan and follow the steps. You can always rely on Safe Mode with Networking to allow the AV engine to fully work to all its capacities. Remember that this is not the method to unlock files encrypted during the malware attack. For that, you need to follow to the end for the decryption and file recovery options.

First steps when dealing with ransomware like .zida files virus

You need to take the fact that Zida ransomware is not a new threat into consideration. This feature means that there are various code lines and issues that malware creators have already thought about and may run processes that disable some security functions and file recovery programs, so you have fewer options.

The file that demands ransom appears after the locking, so you may already see .zida at the end of your images, documents or archives when the following note appears on the desktop:

When you receive the ransom note file with a money-demanding message, you should consider the options for the termination of this threat, instead of the paying. It is not recommended to even consider paying these criminals behind the Zida ransomware virus because hackers and extortionists only care for your money.

zida files virusZida ransomware - the virus that locks files and marks them with .zida appendix.

The issue with all these ransomware-type intruders, that scares people the most is file-locking. The encryption process allows the malware to lock files, change the original code, lock those images, document, and so on, so the victim cannot open those files and decides to pay up. You shouldn't delete Zida ransomware files right away if you want to decrypt files later on. Such a process may require executables and other files.

However, it is not possible to decrypt .zida virus right not, so we recommend relying on other methods. Even though you can rely on the tool that allows you to recover some formats of these files.[5] The best option is to replace files from your backup or use the third-party software.

We mentioned that Zida ransomware removal is the best when you use security tools, AV programs, but these applications NOT gonna recover your encrypted files. Security software is designed to find malicious files, programs and clear them, not to replace affected documents or images with new ones.

It is important to delete these malicious files from quarantine to remove them fully right away. Also, clearing the Zida virus damage in the system is important when you rely on system functions for file recovery is crucial, so run FortectIntego after the virus removal.

Encryption starts right away

The payload file of the ransomware gets dropped when the user initiates the download, in most cases, unknowingly. This process gets triggered during the shady update installation or pirated software install. It is known that malicious files get added in packages of video game cheats, licensed versions of some tools, programs.

Also, malware gets injected on Microsoft documents attached to spam emails often marked as financial information notifications from some companies, services, providers, or popular platforms. You need to pay attention to any suspicious details if you want to avoid such infiltration because you cannot control the infections and the encryption that happens quickly and right after the infiltration.

When the malicious macro[6] or additional technique releases the malware and ransomware payload encryption is triggered, so your data gets affected and unopenable. If you delete any suspicious emails without hesitation, you can avoid serious infections.

Zida ransomware virus removal guide including anti-malware tool scan

When you encounter the infection like this file-locking Zida ransomware virus, you need to clear the damage, get rid of the threat, and then fully clear all the traces because ransomware can spread further quickly. If that happens the renewal of encryption functions and malware processes can run again.

Zida ransomware removal procedures come in stages, depending on the recovery method you may like to use. If you still expect to get your data decrypted after some time, you need to store malicious data, encoded files on the external device and then run the tool like SpyHunter 5Combo Cleaner or Malwarebytes to clear the infection.

When you want to fully remove Zida ransomware and proceed with data recovery using other methods like data backups or third-party software, you need to make sure that all the traces that possibly can affect the performance are repaired. You can do so with FortectIntego that is designed to repair some functions. Before launching the AV engine, reboot machine in Safe Mode with networking.

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
