What type of threat are you dealing with

.[mr.helper@qq.com].dewar files will try to lock your files, which is why it’s categorized as file-encrypting malware. More commonly, it is referred to as ransomware. If you recall having opened a spam email attachment, pressing on a weird ad or downloading from sources that would be categorized as unreliable, that’s how you may have gotten the threat. We will discuss these methods in more details and provide tips on how to avoid a possible infection in the future. Handling a file-encrypting malware infection may have very severe consequences, thus it’s essential that you are informed about its distribution methods. If ransomware was not known to you until now, it could be very unpleasant to realize that you can’t open your files. Soon after you see that something is wrong, a ransom message will pop-up, which will explain that if you wish to get your files back, you need to pay the ransom. Don’t forget who you are dealing with if you consider paying the ransom, because we doubt criminals will take the trouble to send you a decryption utility. It would be more likely that they won’t send you a decryptor. Ransomware does damage worth hundreds of millions to businesses, and by paying, you’d only be supporting that. Something else you ought to consider is that a malicious software researcher may have been able to crack the ransomware, which means a free decryption tool might be available. At least try to find a decryptor before you give into the demands. If you did take care to set up a backup, you can recover them after you eliminate .[mr.helper@qq.com].dewar files.

How is ransomware distributed

In this section, we will discuss how your system might have acquired the infection in the first place. Ransomware tends to stick to simple ways, but that is not to say that more elaborate ones won’t be used as well. What we mean are ways sending spam emails or concealing the malware as a legitimate download, basically ones that only need low-level skill. Infecting a system by opening an email attachment is possibly most common. Criminals attach an infected file to an email made kind of legitimately, and send it to future victims, whose email addresses were sold by other criminals. Normally, those emails are quite obvious, but if you have never come across them before, it might not be so. You can notice particular signs that an email could be malicious, such as the text being full a grammar mistakes, or the sender’s email address being nonsensical. It wouldn’t be shocking if you encountered known company names like Amazon or eBay because people would be more trusting with senders they know. You can never be too cautious, thus, always check if the email matches the sender’s actual one. A red flag ought to also be the sender not addressing you by name in the greeting, or anywhere else in the email for that matter. Senders who claim to have some kind of business with you would not use general greetings like User, Customer, Sir/Madam, as they would be familiar with your name. For example, Amazon automatically includes customer names (or the names users have provided them with) into emails they send, therefore if it is legitimately Amazon, you will find your name.

In case you want the short version, always check sender’s identity before opening an attachment. Be cautious and not press on ads when you are visiting certain, dubious reputation pages. By pressing on an infected advertisement, you might end up permitting dangerous malware to slither into your device. Ads are rarely reliable so avoid interacting with them, no matter how intriguing it might be. Do not download from questionable sources because you might easily get malicious software from there. If you’re doing downloads via torrents, you could at least read what other users are saying before you download something. In other cases, malware could also enter via vulnerabilities found in software. Make sure you install updates because of this. Software vendors release vulnerability patches a regular basis, all you have to do is authorize them to install.

What happened to your files

The ransomware will start scanning for certain files to encrypt as soon as you open it. Files that would be encrypted will be documents, media files (photos, video, music) and everything else that might be valuable to you. Once the files are found, they will be encrypted with a powerful encryption algorithm. The file extension added will help you find out with files were locked. A ransom message ought to then appear, which will offer you a decryptor in exchange for money. Ransomware ask for different sums, the decryption program could cost $100 or a even up to $1000. While you are the one to decide whether you will pay or not, do look into the reasons why malicious software specialists don’t recommend paying. Before you think about paying, you should look into all other options to restore data. If the ransomware was crackable, it’s likely malicious software specialists were able to create a free decryption utility. Try to remember maybe you have backed up some of your files somewhere. You should also try to recover files via Shadow Explorer, the ransomware might have not touched the Shadow copies. And if you don’t want to risk endangering your files again, make sure you do regular backups. If you just realized that backup is indeed available, you just need to delete .[mr.helper@qq.com].dewar files, and may then proceed to recover files.
