Bizer virus Removal Guide

What is Bizer ransomware?

Bizer ransomware is a malicious cryptovirus developed to encrypt data and demand ransom

Bizer ransomwareBizer file extension virus is crypto malware that belongs to Dharma ransomware family of ransom-demanding cyber threats.

Bizer ransomware is a cryptovirus designed to lock users' files and mark them with .bizer file appendix. The full file extension pattern of this particular threat looks similar to previous Dharma ransomware versions. Most of the previous variants are using AES encryption algorithm in the data-locking process.[1] However, it is still unknown when discussing this particular version. When targeted files get encoded, this virus places .[silver@decryption.biz].bizer marker at the end. Often this pattern may also include victims' identification number before the contact email. Also, when photos, documents, audio files or archives get this file extension, this virus generates two ransom notes – Info.hta and FILES ENCRYPTED.txt. In the text file, you can see the contact email, and HTML window reveals payment instructions.

Bizer file extension virus is the new variant in Dharma ransomware family that encrypts users files on the targeted system and demands to pay the ransom for the alleged decryption key. This is the main cryptovirus strategy that helps virus developers to gain profit from users directly.[2]

Cybercriminals that developed Bizer ransomware and other versions of the same threat use army-grade algorithms and changes the original code of the file to make it unreadable. The victim cannot use the encrypted file, and the only solution is to recover important documents using data recovery software or replace files with copies from the backup.

Often malware researchers develop decryption tools for these programs and help people to get their files back. However, Bizer ransomware is not decryptable as well as previous versions in the family. This is why you should focus on virus removal first. It might be dangerous to recover files on the device that is still infected with malware because ransomware can perform it second encryption.

So make sure to remove Bizer ransomware from the device entirely and then use your data backups or cloud services to restore data affected by this virus. If you need more help, we have a few suggestions for data recovery software down below. Also, we recommend using anti-malware programs in virus removal and PC repair tools like ReimageIntego to eliminate virus damage before anything else.

Since Dharma ransomware is a threat that was developed and released back in 2016, we know that one of the files placed on the system contains payment instructions and places to purchase cryptocurrency. However, the second file that Bizer ransomware generates after encryption is the ransom note with the contacts information:

all your data has been locked us
You want to return?
write email silver@decryption.biz

Remember that paying for these Bizer ransomware developers shouldn't be considered. Various experts[3] note that less than a half of ransom paying victims get their files back. Keeping contact with malicious actors may lead to permanent data or money loss.

Make sure to perform Bizer ransomware removal as soon as possible. For that, we can suggest entering the Safe Mode with Networking and then scanning the system using anti-malware program. Trustworthy tools designed to fight malware can indicate all possible threats and terminate malicious processes.

Bizer ransomware virusBizer ransomware is a cryptovirus that delivers two files with ransom demanding messages. A text file contains contact information and a separate program window displays payment instructions.

Payload dropper that initiates malicious infection can be found on spam email

The primary technique used to distribute ransomware is malicious script hidden in common files. This script contains ransomware payload dropper that initiates direct installation of malware. You may directly open the executable file on the system that is attached to the email itself or download and open the maliciously infected file that further infiltrates the system with malware.

There are a few malware categories that are designed to spread ransomware on the targeted systems. Trojans or other malware gets on your system from infected files too and then starts their job by infiltrating the malicious ransomware payload on the machine.

Unfortunately, these emails may look legitimate and can contain safe looking files in common formats like EXE, PDF, TXT or even DOC. Malicious actors misuse known company names or services to hide the real purpose of the email so don't be quick to open the email that is sent from PayPal or FedEx, especially when you don't use the service.

Remove all Bizer ransomware virus traces using professional tools

If you want to use your device again, you need to remove Bizer ransomware from the system altogether. We can recommend using reputable anti-malware programs and terminate the malware with all related files or programs. You can use our suggestions or employ anti-malware of your choice.

However, remember to check for virus damage and related traces after Bizer ransomware removal. We can trust and recommend ReimageIntego, SpyHunter 5Combo Cleaner, or Malwarebytes. We also have a few additional tips for you down below. For example, ransomware can disable some functions of security software, so rebooting the device in Safe Mode can assure that the tool works properly.

How to prevent from getting ransomware

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.
