Is this a dangerous malware

[mr.helper@qq.com].dewar ransomware ransomware will do severe damage to your data as it’ll encrypt them. Having a computer contaminated with ransomware could have very serious consequences, which is why it is categorized as such a dangerous infection. As soon as the ransomware launches, it locates specific types of files to lock. Ransomware has particular files it targets, and those files are the most valuable to users. You’ll need to get a special decryption key to recover files but unfortunately, it’s in the possession of people who are responsible for the attack. Do not lose hope, however, as malicious software researchers might release a free decryptor at some point. This may be your sole choice if you don’t have backup.

You will see a ransom note put on your machine after the malware finishes the encryption process. The note should explain what happened to your files and how much you should pay to get them back. Our next statement should not shock you but it’s not suggested to engage with crooks. We wouldn’t be surprised if the crooks do not actually help you but just take your money. Furthermore, the money you give them will go towards supporting future criminal activity, which you may become victim of again. Consider investing into backup. Just uninstall [mr.helper@qq.com].dewar ransomware if you do have backup.

In the next section, we’ll explain how the malware got inside your PC, but to summarize, it was likely spread via spam emails and false updates. The reason we say you likely got it through those methods is because they’re the most popular among crooks.

How does ransomware spread

Spam emails and bogus updates are possibly how you got ransomware, despite the fact that other distribution ways also exist. You need to familiarize yourself with how to spot malicious spam emails, if you believe you contaminated your system by opening a spam email attachment. If you get an email from an unexpected sender, you have to carefully check the contents before opening the file attached. Usually, well-known company names are used because it would lower people’ guard. You might get an email with the sender saying to be from Amazon, alerting you about some kind of weird behavior on your account or a recent purchase. Whether it’s Amazon or some other company, you should be able to easily check whether it’s true or not. Research the company the sender says to be from, check the email addresses that belong to their employees and see if your sender’s is among them. It’s also suggested to scan the added file with a trustworthy scanner for malicious software.

It is also not impossible that fake software updates were how malware managed to get into. False alerts for updates are typically seen when on questionable sites, constantly forcing you into installing updates. In certain cases, when the false update offers pop up via adverts or banners, they appear legitimate. Still, for anyone who knows that no actual updates will ever be offered this way, such bogus notifications will be obvious. Since downloading anything from advertisements is asking for trouble, be cautious about where you download from. If you have automatic updates turned on, programs will update automatically, but if you need to manually update something, you will be alerted via the program itself.

How does ransomware behave

Ransomware has locked your files, which is why you can’t open then. File encryption might not be necessarily noticeable, and would have began quickly after you opened the infected file. A specific file extension will mark files that have been encrypted. As a complex encryption algorithm was used for file encryption, do not waste your time trying to open files. Information about how to recover your files should be on the ransom note. Ordinarily, ransom notes look practically identical, they use scare tactics to intimidate victims, ask for money and threaten with permanent file removal. It is not impossible that cyber crooks behind this ransomware have the sole decryptor but even if that is true, paying the ransom is not recommended. Keep in mind that you would be relying on the people who locked your files in the first place to recover them. Furthermore, you could become a victim again, if criminals know that you are willing to pay.

It is possible you could’ve uploaded at least some of your files somewhere, so try to recall if that could be the case. Or you can backup your encrypted files and hope this is one of those cases when malicious software researchers release free decryption utilities. In any case, you need to remove [mr.helper@qq.com].dewar ransomware from your computer.

Backups need to be made frequently, so we hope you will begin doing that. If you don’t, you might endangering your files again. There is a variety of backup options available, some more pricey than others but if you have valuable files it is worth buying one.
