How to remove Decryptionassistant ransomware and recover files

Complete tips to delete Decryptionassistant ransomware and decrypt data

Decryptionassistant ransomware is a ransomware-type infection mostly spreads in a form of fake Flash Player update. Once after the successful installation, it encrypts all stored files on the compromised host computer and adds “.decryptionassistant.[victim’s_ID]” extension to each of the touched file. For example, a file initially named 1.jpg would become “.decryptionassistant.5B3-300-D0C”.

The HiddenTear based malware uses AES algorithm to lock the file security and then demands ransom payment in bitcoin for the decryption. The ransom demanding message is displayed under “!!! ALL YOUR FILES ARE ENCRYPTED !!!.TXT” that is dropped (onto the desktop) rightly after the files encryption process is done.

The message within this file informs the victims about the files encryption and states that the sole method to recover the files is to purchase a unique decryption tool from the crooks behind the infection. The victims are instructed to write to the listed email address to initiate this process. They can send one encrypted file to test the decryption.

The message also warns the users that renaming the compromised files and/or trying to decrypt them using third-party tool may result in permanent data loss. In most cases with ransomware infection, the decryption is not possible without the involvement of the crooks behind the infection (except for seriously flawed malicious programs).

Despite that, it is strongly not recommended to contact/ pay to the crooks under any circumstances. The crooks might not even be able to help you and restore the files due to the fact that the malware was developed by amateurs. We recommend you remove Decryptionassistant ransomware from the system using some reputable antivirus tool and recover the files using existing backups you have.

Even if you do not have any backups available, you need not to worry because you have at least two data recovery options still available. You should check for Shadow Copies if exist. These automatically created backups sometimes left untouched during the entire process of files encryption. Third party data recovery tools are another data recovery option for you. Refer data recovery section below the post for more on data recovery tips. There, the Decryptionassistant ransomware removal guide is also included for you.

How do ransomware viruses infiltrate system?

Malware including ransomware are distributed through dubious download channels such as p2p networks, unofficial and freeware sites and etc. Illegal activation tools and fake software updaters are also used as well. Cracking tools cause system infections rather than activating licensed software. Fake software updaters infect systems by exploiting bugs/ flaws of outdated software and/or by installing malicious malware.

Scam campaigns are also used to proliferate in malware. Spam emails can have infectious files as attachments or download links. These files could be in any formats, including PDF and Microsoft Office documents, archives, JavaScript, executables and etc. when these files are opened, executed or otherwise clicked – the infection chain is jumpstarted.
