About this threat

.jdyi files file encrypting malware will encrypt your files and you’ll be unable to open them. Ransomware is the name you ought to be more familiar with in regards to this kind of malicious software. There are a couple of ways the infection may have entered your system, probably either via spam email attachments, infected adverts and downloads. It’ll be explained this further in the proceeding section. A file-encrypting malware infection could lead to very severe outcomes, so it’s essential to know its distribution methods. It may be especially shocking to find your files encrypted if you have never happened upon ransomware before, and you have little idea about what it is. Soon after you see that something is wrong, a ransom message will appear, which will reveal that if you want to get your files back, you have to pay money. Remember who you’re dealing with if you consider giving into the requests, because we doubt crooks will bother sending a decryption program. The cyber crooks will probably just ignore you after you make the payment, and we doubt they’ll help you. This, in addition to that money supporting an industry that does millions of dollars in damages, is why giving into the demands is not recommended. There’s a likelihood that a free decryptor has been made, as people specializing in malware in some cases are able to crack the ransomware. Research free decryptor before you even think about paying. For those careful enough to have backup, simply terminate .jdyi files and then access the backup to restore files.

Ransomware spread methods

There are different ways you could have acquired the file encrypting malware. Ransomware generally sticks to simple methods, but more sophisticated ones are used as well. We’re talking about methods such as sending spam emails or hiding malware as valid downloads, basically things that may be done by low-level crooks. You probably picked up the infection when you opened an infected email attachment. The file contaminated with ransomware is added to a kind of legitimate email, and sent to all potential victims, whose email addresses they store in their database. It is not really that surprising that users open these emails, if it is their first time coming across it. If you see that the sender’s email address is completely random, or if there are a lot of grammar mistakes, those might be signs that it is a malicious email, particularly if it is in your spam folder. It should also be mentioned that hackers use popular company names to not rouse distrust. Our recommendation would be that even if you know who the sender is, the sender’s address should still be checked. If the email doesn’t have your name, that ought to raise suspicion. If you receive an email from a company/organization you’ve dealt with before, instead of Member or User, they’ll include your name. For example, Amazon automatically inserts customer names (or the names users have provided them with) into emails they send, therefore if the sender is actually Amazon, you’ll see your name.

In a nutshell, before you hurry to open files attached to emails, make sure the sender is who they claim they are and you won’t be risking losing your files. And when you’re visiting dubious pages, don’t go around interacting with advertisements. If you’re not careful, ransomware may end up entering your computer. Adverts shouldn’t always be relied on so avoid engaging with them, whatever they could be offering. By downloading from unreliable sources, you might also be endangering your device. If you are downloading via torrents, the least you can do is read the comments before you download something. There are also cases where vulnerabilities in programs might be used for the infection to be able to get in. You need to regularly update your software because of that. You just have to install the updates that software vendors make available for you.

How does ransomware act

When the infected file is opened, the threat will search for certain file types. Files targeted for encryption will be documents, media files (photos, video, music) and everything you hold important. The file-encrypting malware will use a strong encryption algorithm for file encryption once they have been found. The file extension attached will help you find out with files have been affected. The ransom message, which you should notice soon after the ransomware is finished locking your files, will then ask payment from you to get a decryptor. How much you are demanded to pay varies from ransomware to ransomware, the amount might be $50 or it may be a $1000. While we’ve already stated why we do not suggest paying, in the end, this is your choice. Before you consider paying, you need to look into all other ways to recover data. It’s possible that researchers specializing in malware were able to crack the ransomware and release a free decryption program. You could also just not recall backing up your files, at least some of them. Your device stores copies of your files, known as Shadow copies, and if the ransomware didn’t erase them, you can recover them via Shadow Explorer. We hope you have gotten backup and will start backing up your files, so that this situation doesn’t happen again. If backup is an option, you may proceed to recover files from there after you fully delete .jdyi files.

How to eliminate .jdyi files

Manually uninstalling the infection is possible, but not something that we advise. You may bring about irreversible harm to your machine, if errors are made. Our recommendation would be to obtain a malware removal utility instead. Because those tools are developed to remove .jdyi files and other infections, you should not encounter any problems. However, do keep in mind that a malware elimination software will not help with file recovery, it’s just not able to do that. This means you will have to research how to restore data yourself.
