Backdata@qq.com Ransomware

It might be enough to open the wrong email attachment to let Backdata@qq.com Ransomware into your Windows operating system. If that is the case, the email message should be very convincing, and cyber attackers definitely know how to create one because they might be experienced with spam and phishing emails. We do not deny the possibility that other methods to spread malware could be used, but it seems that spam emails are used most often. They could have been employed to spread such malicious infections as helpfilerestore@india.com Ransomware, newsantaclaus@aol.com Ransomware, and skynet45@tutanota.com Ransomware too. All of them are variants of the Crysis/Dharma Ransomware, and that is why they not only look but also work the same. Although there are more similarities than differences, differences do exist, and we discuss them all in this report. We also explain how to remove Backdata@qq.com Ransomware from the Windows operating system. Note that deleting this threat is crucial.

Did you notice the “.id-[ID].[backdata@qq.com].qwex” extension attached to your personal files? If you did, you should not be able to open these files. That is because Backdata@qq.com Ransomware changes their data to hold them hostage. The infection starts the encryption process as soon as it is executed, and you only have a small window of opportunity to delete this threat, but, most likely, you will not know about its existence until the window entitled “backdata@qq.com” shows up on your screen, or until you discover a file named “FILES ENCRYPTED.txt” created on the Desktop and in the local drive. The text file opens a short message that informs the victim that their files were encrypted and that they must email backdata@qq.com or dta@cock.li for recovery. Because of this alternative email address, the dangerous threat might also be known as Dta@cock.li Ransomware. In any case, it is malicious, and you want to remove it from your operating system as soon as possible. Unfortunately, most victims are stopped in their tracks when they discover that they might be able to decrypt their files using a “decryption tool” offered by the attackers themselves.

Can you trust the decryption tool offered by the attackers behind Backdata@qq.com Ransomware? This is the most important question you need an answer to. According to the instructions displayed on the infection’s window, if you email them to get information about the ransom payment and then pay it, a decryption tool would be given to you right away. Unfortunately, that is unlikely to be the truth. In fact, our entire research team would be shocked to learn that the attackers helped their victims to restore files. It is much more likely that the second you pay the ransom, all communication between you and the attackers will be terminated. Of course, they could keep our email address logged, and, when you least expect it, a new malicious launcher could be sent your way. Overall, it seems like there is no good reason for you to contact your attackers. If your files are backed up, and you still have copies of all of your personal files, paying the ransom should not even cross your mind, but we do not recommend going down that path even if your files are lost.

Deleting Backdata@qq.com Ransomware manually is not the most complicated task of all, but it is much easier to handle if you have previous experience. If you know what you are doing, you should be able to remove this threat quickly. Note that we cannot tell you where the launcher of the infection is, and if you cannot find it, going the alternative route might be a better idea. This alternative route includes installing an anti-malware application. If you have reservations about investing in your virtual security, remember that Backdata@qq.com Ransomware is just one of the many threats that could try to invade your operating system and encrypt, delete, or destroy your files in other ways. You have to be ready to fend off all kinds of threats, and doing that manually can be very difficult, which is why installing an anti-malware app is the right move. The best part is that it can eliminate all existing threats automatically.
