DDE virus Removal Guide
What is DDE ransomware?
DDE ransomware – a dangerous virus that adds .encrypted extension to locked files
DDE ransomware is a file locking virus that asks to contact hackers via fake email address
DDE ransomware is a newly discovered cryptovirus that enters machines via macro-enabled malicious MS office documents. Researchers believe that the virus comes from Crypt888 ransomware family. DDE virus locks up all personal files using AES encryption algorithm and then appends the .encrypted extension. As soon as malware's payload is distributed, it runs a main executable dde_ransomware.exe. Additionally, the wallpaper is removed and replaced with a red one which contains a ransom note. Victims are urged to contact cybercrooks via email@example.com and pay ransom for data release. Hackers also add a twist by stating that decryption is also possible without the personal key.

|Distribution||Macro-enabled MS office files, malicious websites|
|Detection and elimination||Use ReimageIntego or Malwarebytes|
DDE ransomware also displays a pop-up window with the name “HACKER” that shows the following text:
Your important files are encrypted.
If you need them, You can find my KEY to decrypt.
The ransom message is quite baffling, as it is not clear what crooks are talking about. The only way to recover encoded files is by using a unique key which is usually kept on a remote server by criminals. Nevertheless, it seems like DDE ransomware was made as a joke, as the email address “firstname.lastname@example.org” does not exist and has nothing to do with Google.
If you found such message on your screen, you are in bad luck, as it seems like the only reliable way to retrieve access to files is by recovering them from a backup. However, before you proceed with data recovery, you should take care of DDE ransomware removal promptly. We suggest using powerful anti-malware software, such as ReimageIntego or Malwarebytes.
DDE ransomware makes a series of changes to the targeted machine. As soon as it enters, it boots an executable file which is run in the background, modifies Windows Registry to retain persistence and downloads malicious apps using Background Intelligent Transfer Service used by Windows. Finally, malware deletes Shadow Volume Copies.
DDE virus then scans the computer and looks for personal files, including:
- MS Office and OpenOffice documents
- Archives, etc.
As soon as encryption is complete, users lose access to all personal data. The only way to decrypt files is by using backups. Additionally, third-party software may be able to help – please see instructions below.
Security experts recommend you to remove DDE ransomware using reliable anti-malware software. However, you should never attempt to get rid of the virus manually, as you could damage your machine even more.

Pay attention when opening emails from unknown sources – they can hide ransomware inside
Ransomware-type viruses are not a new threat and have been around for over ten years. Unfortunately, it seems like it is not a long enough time for users to learn the very basics of internet security and virtual safety. When asked about cybersecurity, users often do not practice safe browsing and click on various links.
To avoid ransomware infection, please follow these simple tips:
- Install anti-malware software and keep it up to date;
- Always patch the operating system as soon as updates are out;
- Do not open suspicious emails (most of them land in the Spam folder) or its attachments;
- Backup all your files and keep it on a remote device such as a USB stick or a cloud account (OneDrive, iCloud, Dropbox, etc.);
- Do not download cracked software;
- Set all your software to update itself automatically – it is less likely to click on fake update pop-up;
- Scan every executable using security software before opening it;
- Avoid websites of questionable content, such as porn, file-sharing, gambling and other sites.

How to prevent from getting ransomware
Access your website securely from any location
When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.
If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.
Recover files after data-affecting malware attacks
While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.
Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
