DNRansomware virus Removal Guide
What is DNRansomware virus?
All victims of DNRansomware can use the same decryption password to restore their files now
Have you been infected with a ransomware that calls itself DNRansomware virus? If so, you can decrypt your files for free. DNRansomware virus, also known as DN ransomware virus or DoNotOpen ransomware is currently on the hunt for new victims and is believed to be distributed via mail spam campaigns. For data encryption, the virus uses a static key and then launches a lock screen, which contains some information about the infection. According to this ransom note, the virus claims to be using “extremely powerfull new RIJNDAEL encryption.” Let us explain what Rijndael is – it is simply the old name of AES cipher.
During the encryption, this hideous virus adds .fucked extensions to files that it affects. The virus wants to get 0.5 BTC from the victim (and says that it is equal to 864.98 USD, which is absolutely not true). At the moment of writing this article, 0.5 Bitcoin was equal to 460,82 USD. You shouldn’t follow any commands by cyber criminals and insert 83KYG9NW-3K39V-2T3HJ-93F3Q-GT into the password box and click “Decrypt!” This will decrypt all files with .fucked extensions for free. You will also have to scan the system with anti-malware tools such as ReimageIntego or SpyHunter 5Combo Cleaner and see if there are any DNRansomware leftovers. You must remove DNRansomware files in order to clean the system entirely, so be attentive and use proper tools for DNRansomware removal. We definitely do not recommend you to try deleting the virus manually!
How can I avoid ransomware attacks?
Word “Ransomware” instantly reminds us of standard malware dissemination techniques. There is nothing interesting about methods that are used to spread ransomware – cyber criminals typically rely on good old distribution tactics such as mail spam or exploit kits. To spread the virus via email, criminals obfuscate the malicious file by renaming it into something like Document/Invoice/Scan/Report/Phone bill/CV and so on. Sometimes such file has double file extensions such as .pdf.exe, and in such case, it is enough to open the file to activate the ransomware. In some other cases, the attached document contains scrambled text and asks the victim to enable Macros function. If the victim enables this function, the malicious Macro script added to the document downloads the ransomware from a remote server. And finally, we have mentioned exploit kits – these are simply set of tools meant to scan the victim’s system for vulnerable software and use it to infect the computer with malware. Exploit kits are typically hosted on infectious websites, so we suggest you to avoid visiting unknown websites!
How can I remove DNRansomware malware from my computer?
It is easy to remove DNRansomware virus if you have an anti-malware program. If you do not, we highly suggest you install it. It is better to use automatic tool for DNRansomware removal because even if it is a poorly made ransomware, it is still a very dangerous piece of software. You can delete the virus using ReimageIntego or SpyHunter 5Combo Cleaner programs, or Malwarebytes if you wish. Before you start one of these programs, reboot your PC using instructions provided below.
Getting rid of DNRansomware virus. Follow these steps
Manual removal using Safe Mode
Before you start DNRansomware removal, enter this code in the screen lock window: 83KYG9NW-3K39V-2T3HJ-93F3Q-GT. Then your files will be decrypted. Instructions provided below are meant to help you to remove DN ransomware successfully. Keep in mind that computer must be loaded in a Safe Mode with Networking before you run antivirus or anti-malware scan with a proper software.
Manual removal guide might be too complicated for regular computer users. It requires advanced IT knowledge to be performed correctly (if vital system files are removed or damaged, it might result in full Windows compromise), and it also might take hours to complete. Therefore, we highly advise using the automatic method provided above instead.
Step 1. Access Safe Mode with Networking
Manual malware removal should be best performed in the Safe Mode environment.
Windows 7 / Vista / XP
- Click Start > Shutdown > Restart > OK.
- When your computer becomes active, start pressing F8 button (if that does not work, try F2, F12, Del, etc. – it all depends on your motherboard model) multiple times until you see the Advanced Boot Options window.
- Select Safe Mode with Networking from the list.
Windows 10 / Windows 8
- Right-click on Start button and select Settings.
- Scroll down to pick Update & Security.
- On the left side of the window, pick Recovery.
- Now scroll down to find Advanced Startup section.
- Click Restart now.
- Select Troubleshoot.
- Go to Advanced options.
- Select Startup Settings.
- Press Restart.
- Now press 5 or click 5) Enable Safe Mode with Networking.
Step 2. Shut down suspicious processes
Windows Task Manager is a useful tool that shows all the processes running in the background. If malware is running a process, you need to shut it down:
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Click on More details.
- Scroll down to Background processes section, and look for anything suspicious.
- Right-click and select Open file location.
- Go back to the process, right-click and pick End Task.
- Delete the contents of the malicious folder.
Step 3. Check program Startup
- Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
- Go to Startup tab.
- Right-click on the suspicious program and pick Disable.
Step 4. Delete virus files
Malware-related files can be found in various places within your computer. Here are instructions that could help you find them:
- Type in Disk Cleanup in Windows search and press Enter.
- Select the drive you want to clean (C: is your main drive by default and is likely to be the one that has malicious files in).
- Scroll through the Files to delete list and select the following:
Temporary Internet Files
- Pick Clean up system files.
- You can also look for other malicious files hidden in the following folders (type these entries in Windows Search and press Enter):
After you are finished, reboot the PC in normal mode.
Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from DNRansomware and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes
How to prevent from getting ransomware
Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
