Remove Omfl ransomware (Decryption Methods Included) - Free Guide

removal by Alice Woods - - | Type: Ransomware

Omfl virus is a malicious program made to lock all personal files on a Windows computer

Omfl ransomwareOmfl ransomware is a virus that manages to affect various parts of the machine.

Omfl ransomware is a cryptovirus designed to encrypt all personal data on the computer and then demand ransom for its return. Once inside the system, it locks all personal pictures, videos, documents, archives, and other files by using the RSA encryption algorithm, which also appends a .omfl extension in the process. Victims can no longer access these files, and they also lose the regular icons, replacing them with blanks.

As soon as the encryption procedure is complete, the virus drops a ransom note _readme.txt – instructions from cybercriminals. It explains to victims what happened to their files and claims that the only method to return them is by paying a ransom for a decryption tool. For negotiation purposes, crooks also provide emails – helpmanager@mail.ch, restoremanager@airmail.cc.

Omfl virus belongs to a ransomware family known as Djvu. This particular malware is notorious within the cybersecurity field, and researchers have been investigating it since its release in 2017. So far, threat actors released at least 270 variants, the latest ones being Vpsh, Nobu, Booa. Unfortunately, the strain can only sometimes be decrypted with the help of Emsisoft's decryption tool – it only possible for victims whose data was locked with an online ID. Otherwise, decryption possibilities are limited, although always worth trying – we provide them below.

File recovery  If no backups are available, recovering data is almost impossible. Nonetheless, we suggest you try the alternative methods: media file repair tool; Emsisofts't decryption option
Malware removal  Perform a full system scan with powerful security software and remove Omfl ransomware
System fix Malware can seriously tamper with Windows systems, causing errors, crashes, lag, other issues. To repair the OS we recommend scanning it with the ReimageIntego tool

While it is true that Omfl 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. The ransom note contains various claims that should encourage people to pay up, but that should be ignored.

This malware only attacks Windows computers mostly by using software cracks downloaded from insecure sources, such as torrent sites. Once inside, it uses a powerful encryption algorithm[2] to lock up all documents, archives, videos, music, and other files, adding .omfl extension to them. After that, ransomware delivers a ransom note text file, which includes instructions on how to recover the encrypted data.

According to virus authors, victims need to contact them via email and provide their personal ID. Once that is done, users should receive further instructions to proceed with the payment, provided in Bitcoin cryptocurrency. Nonetheless, we do not recommend contacting the attackers because they might not deliver the required decryption tool. Removing the virus and going for alternate methods is more reliable.

Threats like this are known for accessing user machines without permission and encrypting all files on them. This way, cybercriminals behind the attack can ask for a ransom payment in return for a unique key. You should remove Omfl ransomware once you receive the message and make sure to clear the system.

You should focus on the proper Omfl ransomware removal process so the system is cleaned and the virus terminated fully. It is possible with SpyHunter 5Combo Cleaner or Malwarebytes or other anti-malware tools. This is how the detection[3] of the malicious file shows where the infection is. Also, to remediate the system and ensure that it works well (some malware might corrupt Windows system files, making it crash, deliver errors, lag, etc.).

Unfortunately, the Omfl virus triggers other malicious processes within the computer, for example:

  • Changes Windows registry database
  • Deletes Shadow Volume Copies to prevent and easy file recovery
  • Inserts malicious modules into browsers to gather sensitive data
  • Alters Windows “hosts” file to prevent users from accessing security websites, such as 2-spyware, etc.

Due to this, malware elimination is one of the main priorities, although this should not be done until all the most important encrypted files are copied to another medium. Keep in mind that there is no malicious code stored within the encrypted files, so copying over is safe.

The decryption methods of .Omfl virus files

The system gets significantly affected, but the issue with this infection is not ending with Omfl ransomware encryption. The worst thing for the victim is to repair those files and other damage that the threat creates. You need to remember that decryption is not possible due to the newest changes criminals made to the coding.

.Omfl file virus is using an online ID creation method that makes this ransomware more dangerous and those files that get locked undecryptable. The key needed for the decryption of these files is created uniquely for each victim and the affected device, so researchers cannot help.

Virus decryption is only possible when the offline ID forming method is used, or the researcher releases a tool working for any encoded data. The best option is to remove the threat and rely on your file backups that can be helpful with your altered files. You can replace locked data using save copies. It is also possible to store some of the encoded files and other malware-related data on the external device, so you can wait for the official decryption tool release.

Remove Omfl ransomware virus by employing robust AV

The worst thing about this Omfl virus infection is its ability to lock all personal data on the infected device. However, without eliminating the virus, you cannot restore those files. However, if you have no backups to restore your data from, you should first copy it over to an external drive or another storage device in case the ultimate solution is provided by security researchers in the future.

Only after you backed your data, you can proceed with the Omfl ransomware removal with tools such as SpyHunter 5Combo Cleaner or Malwarebytes, and then attempt to recover your data using alternative methods, such as Windows Previous Versions or third-party recovery tools. Emsisoft's decryptor might also help some victims, although it is unlikely to happen right away since victims with the same key need to contact security experts and share it with them so they could add it to the database of the tool. Thus, if the decryptor tells you that your files were encrypted with an offline ID, you might have a chance to restore them all in the future.

When you remove Omfl ransomware, other malware, and all the malicious modules, you should also employ ReimageIntego to repair your computer system files that might have been damaged during the infection process of the virus. This program can fix issues created by the malware-related processes.

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

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
