Zwer File-Encrypting Malware Removal [Explained]

What is Zwer File-Encrypting Malware

Zwer File-Encrypting Malware or Zwer ransomware, is malware that belongs to the Djvu ransomware family. The group is spewing out new versions left and right, and there currently are hundreds of them. They’re all generally the same, they spread using the same methods, and demand the same sum of money. All new versions have different extensions that are added to encrypted files, and this one adds .zwer, hence why it’s called Zwer ransomware.

Once it encrypts files, you will be unable to open them until you get a decryptor. The crooks behind this ransomware will offer you a decryption tool for $490/$980 but we discourage you from buying it. Cyber criminals aren’t known to be reliable people, and there’s nothing stopping them from simply taking your money and not giving you anything. This happens all the time, and users are left with encrypted files and no money. By paying, you’d also be encouraging these cyber crooks to continue their malicious activities.

If you have backup for your encrypted files, first remove Zwer File-Encrypting Malware from your computer fully and only then connect to your backup. Otherwise, those copies of your files may get encrypted as well.

How does ransomware spread?

Users usually pick up ransomware when they open malicious spam emails, download pirated content via torrents, etc.

Spam emails are one of the most common ways you can infect your computer with ransomware. Infected files are attached to spam emails, and when users download and open the file, they initiate the ransomware. Malicious emails carrying infections are usually fairly obvious. They are sent from weird email addresses made up of random letters and numbers, contain loads of spelling and grammar mistakes, and pressure users to open the attachment. Any unsolicited email that has an attachment should be regarded with suspicion. And unless you are sure the file is safe, you should not open it. To be sure, you should scan email attachments with anti-malware software or VirusTotal before opening them.

Malware is also often distributed via torrents, especially torrents for pirated TV shows, movies, games and software. If you download pirated content via torrents, you’re not only essentially stealing but also putting your computer at risk of infection. If you are going to download torrents, at least make sure they are safe.

You should also regularly update your system and programs. Updates patch known vulnerabilities which could allow malware to get in, so do not ignore updates.

What does Zwer File-Encrypting Malware do?

As soon as the ransomware initiates, it will start encrypting files. It targets photos, videos, documents, etc., and add the .zwer file extension to them. Once files are encrypted, you will be unable to open them. A _readme text file will be placed in all folders containing encrypted files, and it acts as the ransom note. The note is identical to the ones used by previous versions of this ransomware. The note explains that files have been encrypted and that you can get them back by paying the ransom. Victims are requested to pay $980, or $490 if they contact crooks within the first 72 hours. Since there is no way of knowing whether you’ll actually receive the decryptor, we do not recommend paying the ransom.

Ransomware is one of the most important reasons why you should regularly back up your files and store them somewhere safe. If you have backed up files prior to infection, you can recover them as soon as you delete Zwer File-Encrypting Malware.

If you do not have backup, you need to be very careful with decryptors that are offered on the Internet. First of all, there is a free Djvu ransomware decryption tool developed by malware researchers available here. It does not work on all versions, but it may be worth a shot. Second, a different ransomware gangs has disguised its malware as a decryptor for Djvu. When users download and try to use the fake decryptor, their files are encrypted with Zorab ransomware. It’s a pretty dirty trick, even for cyber crooks. So before you download a Zwer decryptor offered for free, make sure it’s real.

Option 1: use a free decryption tool

You might be lucky enough to find a free decryption tool released by malware researchers or cybersecurity firms. It may be released sometime in the future, even if it is not currently available. A decryptor can usually be found via Google or on a page like NoMoreRansom.

Option 2: use file recovery programs

Depending on the circumstances, a file recovery program might be able to help you recover files. Sadly, we can’t guarantee file recovery.

These software might be of help.

  • Data Recover Pro. While it doesn’t decrypt affected files, Data Recovery Pro will check your hard drive for copies of the files.

Use the official¬†web page to download Data Recovery Pro. It’s not difficult to use the application, all you have to do is launch it and scan your computer. You can restore any files that come up.

  • Shadow Explorer. If the ransomware didn’t delete the shadow copies of the files, Shadow Explorer ought to be able to retrieve them.
    Zwer File-Encrypting Malware

Shadow Explorer has an official website where you can download it from, and installing it shouldn’t be complicated. In the opened program, pick the disk in which files you want to restore are stored. If Shadow Explorer discovers any files it can recover, right-click on them and click Export. In order to leave users with no option but to pay the ransom, ransomware does delete the shadow copies in many cases.

In order to stop potential file loss from occurring in the future, begin routine file backups. It’s also recommended to use anti-virus software with ransomware protection. In case of a repeat infection, harm by ransomware would be prevented by the anti-virus software.
