Decrypthelp@qq.com is the name of a ransomware virus that belongs to the infamous Dharma/Crysis family. Geologically it's a variation of .java ransomware, which has already been circulating on the Internet and attacking PC users for a couple of years.

AES cryptography enables the malware to lock personal files and render them useless. Every corrupted file is consequently attacked with a .[decrypthelp@qq.com].java file extension. Extortionists leave no way to manually decrypt infected files. As they explain on a ransom note, to decrypt files encrypted by Decrypthelp@qq.com, the victim has to pay a ransom. 

If the victim dismisses the claim, he or she risks losing personal data, which is stored on the infected system in the most popular file types. 

Upon successful data encryption, the Decrypthelp@qq.com ransomware unravels a text file instructing the victim on how the payment for a decryptor has to be made:

Your computer has been infected with Decrypthelp@qq.com Ransomware. All the files found on your drives have been encrypted with a complex algorithm. To regain your access, strictly follow the instructions, provided in the ransom notification.

Decrypthelp@qq.com.java ransom note contains a link to Bitcoin wallet, meaning that the ransomware accepts the ransom in Bitcoins only. Regardless of the digital currency accepted, cybersecurity law enforcement foster computer users not to pay the ransom. They ground such recommendation on several factors. First of all, the developers of the Decrypthelp@qq.com.java cannot be trusted because there is no evidence that they contain a decryption key at all. Second of all, crooks can provide victims with a decryptor that is capable of unlocking few file types only. The goal of ransom extortionists is to maximize their profit at any cost. 

Based on the above perspectives, Decrypthelp@qq.com removal is the priority choice. Do not establish a connection with cybercriminals. Each transaction received by ransomware developers motivates them to initiate further illicit activities. 

To remove Decrypthelp@qq.com ransomware from the system, our top pick security tool is Reimage. This anti-malware solution encompasses multiple features, including but not limited to PC's cleanup, file restore, removal/replacement of corrupted Windows Registry entries, fix of compromised system's processes. 

Due to the multiplicity of unauthorized system's changes initiated by crypto-malware, manual Decrypthelp@qq.com removal is hardly possible. By initiating the analysis and modifying random system's files on your own, you can violate system's integrity and end up with a fatal crash. To prevent such kind of scenario, dedicate virus removal procedure to a professional, i.e., a robust antivirus utility. 

Decrypthelp@qq.com virus removal will not recover the data automatically. To restore the files to the state before the attack, you have to pay for the decryptor, but that's not recommended. Another, recommended, the solution is to use backups if you have them or try to decrypt locked files with the help of third-party recovery software. A comprehensive virus removal guide and data recovery tips are submitted at the bottom of this article. 

Ransomware proliferation accelerated by active freeware downloads

Ransomware payloads are actively circulating on the Internet as attachments of malicious spam emails. Malspam is a well-known malware distribution strategy misused by cyber crooks for more than a decade. 

Infected email messages can be differentiated from the others by the content. Usually, they report some problems with the credit or debit cards. Product delivery problems are yet another heated topic used in social engineering attacks. To look more realistic, such messages might mimic the record keeping and stylistics of official documents or contain fake scanned files. Experts warn that spam email attachments can end up with the infection of severe cyber infection. Although the list is not definite, these are the most frequent types of malware hidden under spam email attachments: 

  • fake updates;
  • downloads of rogue PC optimizers and anti-spyware;
  • adverts injected with javaScripts;
  • exploit kits.

Some basic behaviour tips on the Internet should be sufficient for you to protect the system from malware. Pick out the websites to visit carefully. Avoid landing on unknown web domains and random bypass links on them. Besides, to minimize system's vulnerability to cyber attacks, establish powerful virus protection. For this purpose, download a reputable antivirus and update it on a regular basis. Real-time protection is a must-be feature of a security tool. 

TIP: protect your data in the most primitive way – create backups. Having your files on an external drive will save your day in case of ransomware infection.
