RADIYU Ransomware 🔐 (.RADIYU File) — Removal Guide

The Radiyu virus belongs under the ransomware type of infection. A harmful program of this type encrypts all the data on your PC (images, documents, excel tables, audio files, videos, etc) and appends its extra extension to every file, creating the Radian_Radiware_Radiyu.exe files in each folder containing encrypted files.

There is a free decryptor available for this ransomware. In the ransom note window – Radian_Radiware_Radiyu.exe – type the number “43” in the field below. This will get your files back, though this may change in future.

It is better to prevent, than repair and repent!

What is known about the Radiyu virus?

Radiyu will append its specific .Radiyu extension to the title of each encoded file. For example, an image named “photo.jpg” will be changed to “photo.jpg.Radiyu”. In the same manner, the Excel table with the name “table.xlsx” will be renamed to “table.xlsx.Radiyu”, and so on.

In each directory with the encoded files, a Radian_Radiware_Radiyu.exe file will appear. It is a ransom money note. Therein you can find information about the ways of contacting the racketeers and some other remarks. The ransom note usually contains instructions on how to buy the decryption tool from the tamperers. That is how they do it.

How did my machine catch Radiyu ransomware?

There are many possible ways of ransomware injection.

There are currently three most exploited ways for evil-doers to have the Radiyu virus working in your system. These are email spam, Trojan introduction and peer file transfer.

• If you open your inbox and see emails that look just like notifications from utility services companies, delivery agencies like FedEx, web-access providers, and whatnot, but whose addresser is unknown to you, be wary of opening those letters. They are very likely to have a malicious item enclosed in them. Thus it is even riskier to open any attachments that come with emails like these.
• Another option for ransom hunters is a Trojan horse scheme. A Trojan is a program that gets into your computer disguised as something different. Imagine, you download an installer of some program you need or an update for some software. But what is unpacked turns out to be a harmful agent that corrupts your data. Since the installation wizard can have any title and any icon, you have to make sure that you can trust the resource of the things you’re downloading. The optimal thing is to trust the software developers’ official websites.
• As for the peer networks like BitTorrent or eMule, the threat is that they are even more trust-based than the rest of the Web. You can never guess what you download until you get it. Our suggestion is that you use trustworthy resources. Also, it is a good idea to scan the folder containing the downloaded files with the antivirus as soon as the downloading is complete.

How to remove ransomware?

It is crucial to note that besides encrypting your data, the Radiyu virus will probably deploy Vidar Stealer on your computer to get access to credentials to different accounts (including cryptocurrency wallets). That spyware can extract your credentials from your browser’s auto-filling cardfile.

Sometimes racketeers would decrypt few of your files to prove that they indeed have the decryption program. As Radiyu virus is a relatively new ransomware, security software designers have not yet found a method to undo its work. However, the decoding instruments are frequently upgraded, so the effective countermeasure may soon be available.

Of course, if the hackers do the job of encrypting someone’s critical files, the desperate person will most likely fulfill their demands. Nevertheless, paying to racketeers does not necessarily mean that you’re getting your files back. It is still risky. After getting the money, the racketeers may send a wrong decryption key to the victim. There were reports about ransomware developers simply disappearing after getting the money without even writing back.

The best countermeasure to ransomware is to have aan OS restore point or the copies of your essential files in the cloud drive or at least on an external disk. Of course, that might be insufficient. Your most important thing could be that one you were working on when it all happened. Nevertheless, it is something. It is also advisable to scan your PC for viruses with the anti-malware utility after the system restoration.

There are other ransomware products, besides Radiyu, that work similarly. Examples of those are Snet, Press, Shiel, and some others. The two main differences between them and the Radiyu are the ransom amount and the method of encryption. The rest is almost identical: files become encrypted, their extensions altered, ransom notes are found in every directory containing encoded files.

Some fortunate people were able to decode the blocked files with the aid of the free software provided by anti-malware experts. Sometimes the racketeers accidentally send the decryption code to the wronged in the ransom readme. Such an extraordinary fail allows the user to restore the files. But of course, one should never expect such a chance. Make no mistake, ransomware is a bandits’ instrument to pull the money out of their victims.

How do I avert ransomware infiltration?

Radiyu ransomware doesn’t have a endless power, so as any similar malware.

You can defend your system from ransomware attack in several easy steps:

• Never open any emails from unknown mailboxes with strange addresses, or with content that has nothing to do with something you are expecting (how can you win in a lottery without participating in it?). In case the email subject is likely something you are expecting, check all elements of the dubious letter carefully. A fake letter will surely contain mistakes.
• Avoid using cracked or untrusted programs. Trojans are often spreaded as an element of cracked software, possibly as a “patch” preventing the license check. Understandably, untrusted programs are difficult to distinguish from trustworthy ones, as trojans may also have the functionality you seek. Try searching for information about this software product on the anti-malware forums, but the optimal way is not to use such programs at all.
• And to be sure about the safety of the objects you downloaded, use GridinSoft Anti-Malware. This program will be a perfect armor for your system.

Frequently Asked Questions

🤔 How can I open “.Radiyu” files?Is it possible to open“.Radiyu” files?

Negative. That is why ransomware is so frustrating. Until you decode the “.Radiyu” files you will not be able to access them.

🤔 I really need to decrypt those “.Radiyu” files ASAP. How can I do that?

It’s good if you have fаr-sightedly saved copies of these important files elsewhere. Otherwise, you might try to employ System Restore. The only question is whether you have saved any Restore Points that would be helpful now. The rest of the methods require patience.

🤔 You have advised using GridinSoft Anti-Malware to get rid of the Radiyu virus. Does it mean that all my files, currently encrypted, will be removed too?

Of course not. Your encrypted files are no threat to your PC.

GridinSoft Anti-Malware only deals with actual viruses. The ransomware that has attacked your system is most likely still active and running scans periodically to encrypt any new files you might create on your PC after the infection. As it has been said above, the Radiyu ransomware comes with the company. It installs backdoors and keyloggers that can steal your account credentials and provide hackers with easy access to your computer in the future.

🤔 What actions should I take if the Radiyu ransomware has blocked my computer and I can’t get the activation key.

In such a case, you need to have a memory stick with a pre-installed Trojan Killer. Use Safe Mode to do the cleaning. The point is that the ransomware runs automatically as the system boots and encodes any new files created or brought into your computer. To suppress this process – use Safe Mode, which allows only the vital programs to run automatically. Consider reading our manual on running Windows in Safe Mode.

🤔 And what should I do now?

Many of the blocked files might still be within your reach

• If you exchanged your critical files through email, you could still download them from your online mail server.
• You may have shared images or videos with your friends or family members. Simply ask them to send those pictures back to you.
• If you have initially got any of your files from the Web, you can try doing it again.
• Your messengers, social networks pages, and cloud disks might have all those files too.
• Maybe you still have the needed files on your old computer, a portable device, phone, external storage, etc.

USEFUL TIP: You can use data recovery utilities¹ to get your lost data back since ransomware encodes the copies of your files, deleting the authentic ones. In the tutorial below, you can learn how to use PhotoRec for such a restoration, but remember: you won’t be able to do it before you eradicate the ransomware itself with an antivirus program.
