What is Dehd Virus?

Dehd File Virus is a dangerous computer infection. It belongs to the infamous Djvu family. This cunning malware infection can easily get into your computer. Like other ransomware threats, it will encrypt your data and demand ransom money. After successfully encrypting your files, it appends the “.dehd” extension to compromised files. For example, a file named “myphoto.jpg” would appear as “myphoto.jpg.dehd”, which you cannot access.

As mentioned above, you will find the “_readme.txt” ransom note on your PC. It says that all your files are encrypted and you need a private decryption key to unlock those files. The note contains instructions to contact attackers to buy the decryption tool. This nasty Dehd Virus infection will demand ransom money through Bitcoin because it cannot be traced.

Ransom Note left by Stop/Djvu Virus

Dehd Ransomware is a really serious threat to your PC. It can corrupt all your system files and make you unable to access your data. This dubious threat will not allow you to even open your files. It will strictly prohibit any kind of access to encrypted data. If you will move your data to any external storage device still then you will get only the encrypted copy of your files. You will also not be able to access those data on any other computer.

It can also infect the other computer that you will use to access your encrypted data. So don’t try to play games with Dehd Virus. It can cost you much more. Also, take your infected PC offline immediately to protect other devices on your network. It is also not suggested to pay ransom money because it will not decrypt your files.

How it infects your PC?

Dehd File Virus can spread in different ways. It is hard to determine how it got on your system specifically. Cybercriminals mostly use software bundling and spam email campaigns to deliver such threats. When you download any freeware application from shady websites, they might carry malicious attachments. Use the custom installation process and read EULA carefully to avoid the installation of hidden programs. Do not open spam emails from unknown senders and do not click on any link or open attachments without scanning.

Apart from this, Dehd Virus can also get on your system through browsing porn or torrent sites. These kinds of sites cause unwanted and forced redirection of browsers on phishing websites. Those sites most likely host malicious scripts that trigger automatic malware download. Sites asking for cookie permission to show pop-up notifications can also do the same.

Downloading pirated or cracked software and games can also bring threats like Dehd Virus on your PC. These kinds of programs are created by using hack tools, a type of Trojan infection that can be used to deliver threats on the host computer. Installing illegal patches and fake software updates, sharing files on unsafe websites, and using an infected USB drive can bring this virus to your system.

Is my PC infected by Dehd Virus?

If you are unable to open your files, documents, images, videos, etc. on your PC because they have a “.Dehd” extension, then Yes, your computer is infected. These kinds of crypto-virus mainly get installed on the targeted PC through unknown installers and encrypt all the files. In the case of Dehd File Virus infection, you will find no symptoms of infection until all your files and locked.

This nasty virus scans the entire hard drive for files then use its powerful AES/RSA encryption algorithm to encrypt files.

Due to frequent changes to the ransomware variants, security researchers have not been able to develop any free decryptor.

Dehd File Virus infection is quite cunning and its ruse is also very good. It is offering a 50% discount on the ransom fee if victims pay under 72 hours.
