How to remove Zybvqxefmh ransomware

Zybvqxefmh ransomware is a type of virus that encrypts personal files for financial benefit

Zybvqxefmh ransomware is a cryptovirus that belongs to a large malware family known as Snatch. The threat encrypts all the important files (such as pictures, videos, music, documents, etc.) on a Windows computer and appends .zybvqxefmh extension to each of them. From that point in time, users are unable to edit or even open these files. In the ransom note HOW TO RESTORE YOUR FILES.TXT, cybercriminals explain that the only way to recover data is by paying ransom in Bitcoin – the sum can vary, depending on many different factors. For communication purposes, two email addresses – cryptolifeguard@cock.li and unl0ck@keemail.me.

While it is true that Zybvqxefmh virus files require a unique decryption key to unlock them, experts^[1] recommend not paying the ransom, as cybercriminals might not keep their promises, resulting in financial losses. In this article, we will explain how to get rid of malware, use alternative methods for data recovery, and remediate the system as soon as possible.

First spotted by cybersecurity researcher S!Ri^[2] in October 2020, Zybvqxefmh virus is just one of many variants of Snatch ransomware. Previously released versions include Mgyhzbjyhux, Hhmgzyl, Eknkfwovyzb, and many others. While in most cases cybercriminals behind the malware focus on attacking organizations and businesses, the targets are chosen relatively randomly. Despite this this, it is also known that regular computer users can also get infected with this version.

Ransomware is a complicated malicious program that engages in many system modifications as soon as it gains access to a computer or a network. Due to its nature, it might not be possible to restore all Windows system components to previous states after you remove Zybvqxefmh virus. Thus, if you experience system crashes or similar issues, you could employ automatic solutions to fix system damage – we recommend FortectIntego.

After Windows is ready, data encryption is performed. The virus looks for the most commonly used files, such as DOC, PDF, JPG, HTML, ZIP, DAT, and many others. The encryption process prevents all file access and strips them from regular icons, replacing them with blank ones.

As soon as the encryption process is complete, Zybvqxefmh file virus drops a ransom note that explains the victims what happened to their files. The initial sentence seems relatively friendly, as it claims that the files can be “easily” returned:

Hello!
All your files are encrypted, write to me if you want to return your files – I can do it very quickly!
Contact me by email:

cryptolifeguard@cock.li or unl0ck@keemail.me

The subject line must contain an encryption extension or the name of your company!
Do not rename encrypted files, you may lose them forever.
You may be a victim of fraud. Free decryption as a guarantee.
Send us up to 3 files for free decryption.
The total file size should be no more than 1 MB! (not in the archive), and the files should not contain valuable information. (databases, backups, large Excel spreadsheets, etc.)
!!! Do not turn off or restart the NAS equipment. This will lead to data loss !!!

To contact us, we recommend that you create an email address at protonmail.com or tutanota.com
Because gmail and other public email programs can block our messages!

As evident, the attackers claim that the best way to resolve this difficult situation is by paying a ransom. However, security researchers advise focusing on Zybvqxefmh ransomware removal instead. This process can not be performed manually, however, as it requires a deep understanding of IT systems. Instead, security software, such as SpyHunterCombo Cleaner or MalwarebytesMalwarebytes, is the best way when trying to deal with ransomware infection.

Can't open .zybvqxefmh files? Here's what to do next 

Cybercriminals mention in the ransom note HOW TO RESTORE YOUR FILES.TXT, that the data recovery is only possible if the ransom in cryptocurrency is paid. They also offer free decryption of three small files (up to 1MB), which should not contain any important information. This way, they are trying to prove that they can restore .zybvqxefmh files with no problems. Unfortunately, but most of the Snatch variants are not decryptable, so restoration is extremely difficult.

Here is how .zybvqxefmh file encryption works:

• Ransomware infects the computer to weaken Windows defenses and automatic backups.
• It deletes Shadow Copies, which could otherwise be used for swift file recovery.
• Malware begins the encryption process – it utilizes a symmetric AES^[3] encryption algorithm.
• During this process, malware contacts a remote server, provides each of the victims with unique IDs and delivers a decryption key to cybercriminals.
• Since the key is only accessible to threat actors, they remain the only source who would be able to provide it.

While many people believe that they can remove .zybvqxefmh extension after scanning the machine with security software, it is not correct. Anti-malware tools are not designed for the decryption process – they can only delete the malicious files placed by the virus. However, after this, the encrypted data remains unchanged, and users still can not access it.

So, if you ask whether it is possible to restore .zybvqxefmh virus files, the answer is rather difficult and depends on many factors. For example, if you had data backups prepared, you can easily get everything back. Unfortunately, it is usually not the case for the ransomware victims, and the only copies of files they have are the encrypted ones.

If you have no backups, you could either pay the ransom to cybercriminals or employ alternative options we provide in our recovery section below. Paying the ransom is not recommended, as you might lose your money as well – ransomware authors can simply fail to fulfill their promises. On the other hand, alternative solutions might not always be effective.

A correct way to handle Zybvqxefmh ransomware removal

It is important to note that it is always better to protect your system correctly instead of dealing with Zybvqxefmh ransomware removal and data recovery procedures. For that, make sure you use anti-malware software such as SpyHunterCombo Cleaner or MalwarebytesMalwarebytes. These tools can not only delete the existing malware but also prevent the infiltration of ransomware and other threats, stopping the file encryption process. Of course, acting carefully online is also crucial – never open spam email attachments, don't leave the RDP connections open to the internet, use strong passwords, etc.

Before you remove Zybvqxefmh ransomware virus from your computer, you should backup all the encrypted files, as security researchers might create a free decryption tool in the future (note that encrypted data does not hold any malicious code inside). Next, disconnect the computer from the network or any external devices. Finally, initiate a full system scan with anti-malware, and then employ FortectIntego to fix damaged system files that security software can not deal with.

You can still decide to pay criminals if you so desire, but please do it at your own risk – you might suffer significant monetary losses. Instead, we recommend trying the alternative options we provide below.
