How to remove Qqqw ransomware, Decrypt .qqqw files. (2024)

What is Qqqw virus?

Qqqw virus is a new ransomware that belongs to the family of ransomware called STOP (Djvu). Ransomware is a form of malware that encrypts the victim’s files and demands a ransom for decrypting them. The Qqqw virus encrypts files, renames them by appending the .qqqw extension, and creates files named “_readme.txt” containing the ransom demand message. For example, a file named “image.jpg” will be renamed to “image.jpg.qqqw”, a “document.docx” file to “document.docx.qqqw”, “invoice.pdf” to “invoice.pdf.qqqw”, and so on.

Qqqw ransomware is the 377th variant of the STOP (Djvu) ransomware. It is created to encrypt files located on the victim’s computer, and then extort money to decrypt them. Qqqw virus sneaks into the system without any visible symptoms, which is why users notice that their computer is infected too late, when the files are already encrypted. Typically, ransomware like Qqqw can infect a computer when a user runs and installs the infected program as well as cracked games, freeware, key generators and other similar software.

Upon execution, the ransomware creates a directory in the Windows system directory, copies itself to this directory, changes some OS settings, and also collects information about the infected computer. After that, Qqqw virus tries to connect to its command server. If this succeeds, the ransomware sends data about the infected computer to the server, and from it receives a key (so-called ‘online key’) necessary for file encryption. If the connection to its command server has not been established, then the ransomware uses a fixed key (so-called ‘offline key’). The main difference between an online key and an offline key is that the online key is in the hands of criminals and cannot be determined. The offline key is fixed and can be determined by security researchers. This gives hope that victims of Qqqw virus will be able to decrypt files without paying ransom.

A file with extension ‘.qqqw’ is a file that has been encrypted by the Qqqw ransomware and therefore the contents of this file are locked. Each file that has been affected by the virus is renamed in such a way that the ‘.qqqw’ extension is appended to its old name on the right. This means the following, if the file was named ‘document.docx’, then after it is encrypted, it will be called ‘document.docx.qqqw’. Each file on the victim’s computer becomes the target of Qqqw virus. No matter where the file is located, on the internal drive or network storage, this file will be encrypted. The virus only does not encrypt files in the OS system directories, files with the extension .dll, .lnk, .bat, ini, .sys and files named ‘_readme.txt’. Thus, the following types of files can be encrypted:

.xmmap, .hplg, .sie, .mpqge, .slm, .wsd, .py, .map, .vcf, .ods, .vdf, .d3dbsp, .mp4, .pst, .dazip, .gdb, .bkf, .wpa, .xlsb, .ppt, .wpe, .xlgc, .ybk, .crw, .bay, .wmf, .xyw, .raw, .litemod, .ibank, .xls, .arw, .3ds, .fpk, .wbz, .pef, .mdb, .dng, .2bp, .webp, .dmp, .wot, .odp, .menu, .cfr, .pdf, .lrf, .wp4, .xlsx, .bar, .3dm, .pptm, .das, .wsh, .odb, .pak, .mef, .rtf, .doc, .wmo, .mrwref, .lbf, .dba, .p12, .t12, .sum, .wb2, .qdf, .zw, .wma, .mdbackup, .p7c, .mov, .zdc, .t13, .ntl, .dxg, .wn, .wpd, .xlsm, .snx, .sidn, .bik, .wbmp, .1st, .xx, wallet, .avi, .odt, .wp6, .vfs0, .y, .jpe, .srf, .raf, .vtf, .cas, .arch00, .kf, .layout, .yal, .wp5, .wav, .xdl, .mdf, .js, .ai, .qic, .xld, .syncdb, .upk, .xmind, .w3x, .wps, .mlx, .xlk, .xar, .m2, .rb, .eps, .zip, .cr2, .itdb, .0, .dcr, .sb, .pfx, .xyp, .xf, .docx, .7z, .hkx, .wma, .txt, .ncf, .itl, .docm, .png, .asset, .3fr, .mcmeta, .der, .xls, .ysp, .wp, .wire, .desc, .tor, .zi, .psd, .fos, .wgz, .wsc, .wps, .hkdb, .vpk, .wm, .lvl, .ws, .srw, .xlsm, .zabw, .ptx, .ff, .wbc, .rar, .wpt, .vpp_pc, .rofl, .wri, .indd, .xml, .bc6, .epk, .psk, .ztmp, .wbm, .iwi, .erf, .forge, .css, .zip, .webdoc, .xxx, .x3f, .rgss3a, .odc, .rw2, .x3f, .apk, .ltx, .dbf, .sis, .pkpass, .bkp, .xbdoc, .xlsx, .rim, .pem, .sidd, .z3d, .rwl, .db0, .sav, .pdd, .pptx, .orf, .sid, .fsh, .nrw, .sr2, .wdb, .kdc, .svg, .wpd, .yml, .zdb, .wcf, .wdp, .wmd, .bsa, .p7b, .wbd, .re4, .wpl, .gho, .tax, .csv, .xll, .accdb, .big, .wmv, .wotreplay, .iwd, .xdb, .wpg, .xpm, .cdr, .esm, .sql, .xwp, .bc7

As we said, Qqqw file is an encrypted file. To decrypt it, you must use the key and the decryptor. This is reported by the authors of Qqqw virus, in a message that they leave on the infected computer. This message is in a file called ‘_readme.txt’. The criminals place such a file in every directory where there is at least one encrypted file. An example of the contents of this file is given below.

The contents of this file are a ransom demand message. Criminals report that all files on the computer are encrypted, and only the key and decryptor can decrypt these files and restore access to their contents. Attackers demand a ransom of $980 in exchange for a key and a decryptor. If the victim is ready to pay the ransom quickly, within 72 hours, the size of the ransom is halved to $490. The authors of the virus offer to decrypt one Qqqw file for free and thus prove the possibility that the files can be decrypted.

The full contents of the file ‘_readme.txt’:

Threat Summary

Security researchers confirm that files with .qqqw extension are encrypted and to decrypt them you need to use a key and special software – decryptor. Fortunately, there is a free Qqqw File Decrypt Tool. It is a program that can help everyone to decrypt .qqqw files completely free. Unfortunately, this decryptor is limited in that it can only decrypt files encrypted with an offline key, files encrypted with an online key cannot yet be decrypted. The reason for this is that only the Qqqw creators have the online key and this key cannot be determined or cracked. In addition to using the Qqqw File Decrypt Tool, there are several other ways to restore the content of encrypted files.

The instructions below detail how to remove Qqqw ransomware, decrypt .qqqw files, and also how to recover encrypted files if the Qqqw File Decrypt Tool could not decrypt them. Read the entire manual carefully. To make it easier for you to follow the instructions, we recommend that you print it or open it on your smartphone.

How to remove Qqqw ransomware virus

You need to remove the Qqqw ransomware virus and its autostart entries before proceeding to decrypt or restore encrypted files. This must be done since otherwise the ransomware may re-encrypt the restored files. You can stop the ransomware from working, as it is not difficult to do. Another option is to perform a full system scan using free malware removal tools capable of detecting and removing ransomware infection.

It is very important to scan the computer for malware, as security researchers found that spyware could be installed on the infected computer along with the Qqqw ransomware. Spyware is a very dangerous security threat as it is designed to steal the user’s personal information such as passwords, logins, contact details, etc. If you have any difficulty removing the Qqqw virus, then let us know in the comments, we will try to help you.

To remove Qqqw ransomware, follow the steps below:

1. Kill Qqqw virus
2. Disable Qqqw Start-Up
3. Delete Qqqw Task
4. Remove Qqqw virus

Kill Qqqw ransomware

Press CTRL, ALT, DEL keys together.

Click Task Manager. Select the “Processes” tab, look for something suspicious that is the Qqqw ransomware then right-click it and select “End Task” or “End Process” option. If your Task Manager does not open or the Windows reports “Task manager has been disabled by your administrator”, then follow the guide: How to Fix Task manager has been disabled by your administrator.

It is not difficult to detect a process related to the Qqqw ransomware. When looking for a malicious process, pay attention to the process icon and its name. Most often, this ransomware has a process name in the following format: 4-characters.tmp.exe or 4-characters.exe. For example: 7533.tmp.exe, A4b1.exe, CD15.tmp.exe, 19b2.exe. The process name can also contain “(32 bit)”. If you do not find a process with a similar name in the list of processes, then most likely the Qqqw ransomware has finished working. But keep in mind, if you do not remove the ransomware autostart entries, as demonstrated below, and do not delete its file, then after a while it may start again, and if it finds unencrypted files, immediately encrypt them.

Disable Qqqw Start-Up

How to decrypt .qqqw files

All files with .qqqw extension are encrypted and the only way to access their contents is to decrypt them. To decrypt .qqqw files, you need to use a unique key and decryptor. As we said above, Emsisoft company was able to create a decryptor and found a way in some cases to determine the key that was used to encrypt the files. It can help the ransomware victims to decrypt encrypted files for free.

To decrypt .qqqw files, use Qqqw File Decrypt Tool

• Download Qqqw File Decrypt Tool from the following link.
  STOP Djvu decryptor
• Scroll down to ‘New Djvu ransomware’ section.
• Click the download link and save the decrypt_STOPDjvu.exe file to your desktop.
• Run decrypt_STOPDjvu.exe, read the license terms and instructions.
• On the ‘Decryptor’ tab, using the ‘Add a folder’ button, add the directory or disk where the encrypted files are located.
• Click the ‘Decrypt’ button.

Qqqw File Decrypt Tool is a free software that can decrypt files encrypted with an offline key. Unfortunately, files encrypted with an online key cannot yet be decrypted. The online key is unique to each infected computer, and at the moment there is no way to obtain this key. Of course, criminals have this key, but we do not think that paying a ransom is a way to decrypt .qqqw files. In the case when the files are encrypted with an online key, there is a chance to restore the encrypted files using alternative methods, which are described below.

How to find out which key was used to encrypt files

Below we show two ways to help you determine what type of key was used to encrypt the files. This is very important, since the type of key determines whether it is possible to decrypt .qqqw files for free. We recommend using the second method, as it is more accurate.

Find out the type of key using ‘_readme.txt’ file

• Open the ransom demand message (‘_readme.txt’ file).
• Scroll down to the end of the file.
• There you will see a line with the text ‘Your personal ID’.
• Below is a line of characters, this is your personal id.

Find out the type of key using ‘PersonalID.txt’ file

• Open disk C.
• Open directory ‘SystemID’.
• Open file named ‘PersonalID.txt’. This file lists ‘Personal ID’s that match the keys that the virus used to encrypt files.

The ‘Personal ID’ is not a key, it is an identifier related to a key that was used to encrypt files. If the ID ends with ‘t1’, then the files are encrypted with an offline key. If the ID does not end with ‘t1’, Qqqw ransomware virus used an online key. If you could not figure out how to determine which key was used to encrypt files, then we can help. Just write a request here or in the comments below.

Qqqw File Decrypt Tool : “No key for New Variant online ID”

If, when you try to decrypt .qqqw files, Qqqw File Decrypt Tool reports:

No key for New Variant online ID: *
Notice: this ID appears to be an online ID, decryption is impossible

It means that your files are encrypted with an ‘online key’ and their decryption is impossible, since only the Qqqw authors have the key necessary for decryption. In this case, you need to use alternative methods listed below to restore the contents of encrypted files.

Qqqw File Decrypt Tool : “No key for New Variant offline ID”

If, during decryption of .qqqw files, Qqqw File Decrypt Tool reports:

No key for New Variant offline ID: *t1
Notice: this ID appears be an offline ID, decryption MAY be possible in the future.

It means the following: your files are encrypted with an ‘offline key’, but the key itself has not yet been obtained by security researchers, in this case, you need to be patient and wait a while, in addition, you can also use alternative ways for recovering encrypted data.

If for some reason you were unable to decrypt the encrypted files, then We recommend to follow the news on our Facebook or YouTube channels. So you ‘ll know right away that it ‘s possible to decrypt .qqqw files.

This video step-by-step guide will demonstrate How to remove Qqqw virus, Decrypt/recover .qqqw files.

How to restore .qqqw files

If your files were encrypted with .qqqw extension, then there is a chance that you can recover the files without decryption. We recommend using PhotoRec and ShadowExplorer that are designed to find and recover lost and deleted data. Mostly such programs are paid, but these tools can restore your files for free. Each of these programs has already helped many victims to recover encrypted files in what would seem to be the most hopeless cases. We want to remind you that before you try to recover files, you need to scan your computer for ransomware using free malware removal tools. It is very important to find the Qqqw virus and completely remove it.

Use shadow copies to restore .qqqw files

Modern versions of the Windows OS have one very useful feature. The Windows automatically makes copies of the files you use. These copies are called ‘Shadow Volume Copies’ and are not directly visible to the user. ShadowExplorer will allow you to get easy access to these files, and thus restore the original state of encrypted files. Of course, not everything is so simple, unfortunately very often ransomware deletes these copies, thus preventing the simple recovery of encrypted files. But in some cases, copies of the files remain and allow for quick file recovery. Therefore, our opinion, you need to try this method.

First, visit the following page, then press the ‘Download’ button in order to download the latest version of ShadowExplorer.

When the download is finished, extract the saved file to a directory on your device. This will create the necessary files like below.

Launch the ShadowExplorerPortable application. Now select the date (2) that you wish to recover from and the drive (1) you want to restore files (folders) from as shown in the figure below.

On right panel navigate to the file (folder) you wish to restore. Right-click to the file or folder and click the Export button as shown on the screen below.

And finally, specify a directory (your Desktop) to save the shadow copy of encrypted file and press ‘OK’ button.

This video step-by-step guide will demonstrate How to recover encrypted files using Shadow Explorer.

Recover .qqqw files with PhotoRec

There is another very good way to recover .qqqw files – use a tool that finds and restores deleted files. We recommend using PhotoRec. This is one of the few programs that allows you to do this for free. The reason that allows you to recover encrypted files using this method is simple – when you or any program, including the ransomware, deletes a file, this file is not deleted, the Windows OS marks it as deleted and hides it. PhotoRec finds such deleted files and restores them. Thus, at the output, you get files in an unencrypted state. The only thing I want to draw your attention to is that the less you used your computer after ransomware infection, the higher your chance of recovering encrypted files.

Download PhotoRec on your Windows Desktop from the link below.

When the download is finished, open a directory in which you saved it. Right click to testdisk-7.0.win and choose Extract all. Follow the prompts. Next please open the testdisk-7.0 folder as shown on the screen below.

Double click on qphotorec_win to run PhotoRec for Windows. It’ll show a screen like below.

Select a drive to recover as displayed below.

You will see a list of available partitions. Select a partition that holds encrypted personal files as on the image below.

Click File Formats button and choose file types to restore. You can to enable or disable the restore of certain file types. When this is complete, click OK button.

Next, click Browse button to choose where recovered photos, documents and music should be written, then press Search. We strongly recommend that you save the recovered files to an external drive.

Count of restored files is updated in real time. All recovered photos, documents and music are written in a folder that you have selected on the previous step. You can to access the files even if the recovery process is not finished.

When the restore is done, click on Quit button. Next, open the directory where recovered files are stored. You will see a contents like below.

All restored photos, documents and music are written in recup_dir.1, recup_dir.2 … sub-directories. If you’re looking for a specific file, then you can to sort your restored files by extension and/or date/time.

This video step-by-step guide will demonstrate How to recover encrypted files using PhotoRec.

How to protect your PC from Qqqw ransomware

Most antivirus software already have built-in protection system against the crypto malware. Therefore, if your personal computer does not have an antivirus program, make sure you install it. As an extra protection, run the HitmanPro.Alert. HitmanPro.Alert is a small security utility. It can check the system integrity and alerts you when critical system functions are affected by malware. HitmanPro.Alert can detect, remove, and reverse ransomware effects.

Visit the following page to download the latest version of HitmanPro Alert for Windows. Save it directly to your Microsoft Windows Desktop.

Once the download is done, open the file location. You will see an icon like below.

Double click the HitmanPro Alert desktop icon. When the utility is started, you’ll be displayed a window where you can select a level of protection, like below.

Now click the Install button to activate the protection.
