Additionally, contaminating a system is very easy, which is one of the reasons why ransomware is considered to be highly harmful. People most often get infected via spam emails, malicious adverts or bogus downloads. And once it’s opened, it will start encrypting your data, and once the process is finished, it will demand that you pay money to get a decryptor, which theoretically ought to recover your data. How much is demanded of you depends on the file encrypting malware, some ask for thousands of dollars, some for less than $100.

Consider investing the money into some type of backup, so that if this were to reoccur, you wouldn’t be endangering your files. We’re certain you will find a suitable option as there are many to choose from. You can restore data after you terminate .[mr.helper@qq.com].dewar files if you had backup already prior to the infection entering your device.

How does data encrypting malicious software spread

You normally get the ransomware when you open an infected email, tap on an infected ad or use questionable platforms as download sources. It does, however, occasionally use methods that are more sophisticated.

Since you might have gotten the data encrypting malicious software via email attachments, try and remember if you have recently downloaded something strange from an email. You open the email, download and open the attachment and the file encrypting malware is now able to start encrypting your files. Those kinds of emails commonly end up in spam but some users think they’re legitimate and move them to the inbox, thinking it’s important. The use of basic greetings (Dear Customer/Member), strong encouraging to open the file added, and obvious mistakes in grammar are what you need to look out for when dealing with emails that contain files. If the email was from a company whose services you use, they would have automatically put in your name into the email, instead of a general greeting. Don’t be shocked if you see big company names (Amazon, eBay, PayPal) be used, because when people see a known name, they are more likely to let down their guard. It could have also been the case that you clicked on the wrong advertisement when browsing suspicious sites, or downloaded something from a source that you should have avoided. If you regularly engage with advertisements while on questionable websites, it is no wonder your device is infected. Avoid untrustworthy sites for downloading, and stick to legitimate ones. Sources such as advertisements and pop-ups are infamous for being dangerous sources, so never download anything from them. If an application needed to update itself, it wouldn’t notify you via browser, it would either update without your interference, or alert you via the software itself.

What happened to your files?

Infection that leads to permanent data loss is not an impossible scenario, which is what makes a file encrypting malicious software so dangerous. The process of encrypting your files isn’t a long process, so it’s possible you won’t even notice what is going on. Strange file extensions will be added to all affected files, and they’ll usually indicate the name of ransomware. Strong encryption algorithms will be used to lock your data, which can make decoding files for free pretty difficult or even impossible. When encryption is complete, a ransom note will appear, which is intended to explain to you what you need to do next. Even though you will be offered to buy a decoding utility, paying for it is not suggested. Crooks might just take your money without giving you a decryptor. The ransom money would also possibly go towards funding future data encoding malicious program activities. And, people will increasingly become attracted to the already highly profitable business, which reportedly made $1 billion in 2016 alone. You might want to consider investing into backup with that money instead. Situations where your files are put in danger might happen all the time, but if you had backup, file loss would not be a possibility. We would recommend you do not pay attention to the demands, and if the infection still remains on your device, erase .[mr.helper@qq.com].dewar files, for which you will find instructions below. If you become familiar with the spread methods of this infection, you ought to be able to avoid them in the future.
