What is Yguekcbe ransomware?
Yguekcbe ransomware is a malware program (a virus) that is designed to make money in a very specific way. First, it encrypts all files on the target computer using a cryptographic algorithm. This process renders the files inaccessible, but it is reversible. The virus then offers to do just that, to decrypt the files; that, however, would cost victim money. These viruses are called ransomware because this process essentially holds the files for ransom.
When Yguekcbe encrypts files, it also changes their names, adding .yguekcbe file extension. In fact, this is how the virus got its name. It also leaves a ransom note, “HOW TO RESTORE YOUR FILES.TXT”, on the Desktop. The image above contains the full text of the note, but we will also summarize it in the next paragraph.
The note indicates that Yguekcbe virus is designed to target companies, though of course, private individuals may also fall victim to it by accident. The hackers do not specify the ransom amount, only their contact information. Presumably this is because they intend to negotiate.
Contacting the hackers is a bad idea; in many cases they just ignore their victims after receiving payment. And if you really are just a citizen whose computer got infected with Yguekcbe by mistake, they likely wouldn’t even talk with you. This is why you should follow our guide, which will describe how to remove Yguekcbe ransomware and decrypt .yguekcbe files without their involvement.
How to Remove Yguekcbe Ransomware
If you have working backups of your encrypted files or you are not going to try and recover lost files, then scan your computer with one or several antivirus and anti-malware programs or reinstall the operating system altogether.

How to Recover Files Encrypted by Yguekcbe Ransomware
If you want to recover files encrypted by ransomware you can either try to decrypt them or use methods of file recovery.
Ways to decrypt the files:
- Contact the ransomware authors, pay the ransom and possibly get the decryptor from them. This is not reliable: they might not send you the decryptor at all, or it might be poorly done and fail to decrypt your files.
- Wait for security researchers to find some vulnerability in the ransomware that would allow you to decrypt files without paying. This turn of events is possible but not very probable: out of thousands of known ransomware variants only dozens were found to be decryptable for free. You can visit NoMoreRansom site from time to time to see if free decryptor for Yguekcbe exists.
- Use paid services for decryption.
Other ways to recover encrypted files:
- Restore from backup. If you make regular backups to a separate device and check from time to time that those are in working order and files can be successfully restored – well, you probably won’t have any problems getting back your files. Just scan your computer with a couple of AVs and anti-malware programs or reinstall the operating system, and then restore from backup.
- Recover some files from cloud storage (DropBox, Google Drive, OneDrive, etc.) if you have one connected. Even if encrypted files were already synced to the cloud, a lot of cloud services keep old versions of altered files for some time (usually 30 days).
- Recover Shadow Volume Copies of your files if those are available – ransomware usually tries to delete them too. Volume Shadow Copy Service (VSS) is a Windows technology that periodically creates snapshots of your files and allows you to roll back changes made on those files or recover deleted files. VSS is enabled together with System Restore: it’s turned on by default on Windows XP to Windows 8 and disabled by default on Windows 10.
- Use file recovery software. This probably won’t work for Solid State Drives (SSD – a newer, faster and more expensive type of data-storage devices) but is worth a try if you store your data on a Hard Disc Drive (HDD – an older type of storage device which generally has more capacity). When you delete a file from your computer – and I mean completely delete: use Shift + Del or empty the Recycle Bin – on an SSD, it gets wiped from the drive right away. On an HDD however, it rather gets marked as deleted, and the space it occupies on a hard drive – as available for writing, but the data is still there and is usually recoverable by special software. However, the more you use the computer, especially if you do something that writes new data on the hard drive, the more chance that your deleted file gets overwritten and will be gone for good. That is why, in this guide we will try to recover deleted files (as you remember, ransomware creates an encrypted copy of a file and deletes the original file) without installing anything on a disk. Just know that this still might not be enough to successfully recover your files – after all, when ransomware creates encrypted files it writes new information on a disk, possibly on top of files it just deleted. This actually depends on how much free space is there on your hard drive: the more free space, the less chance that new data will overwrite the old data.
- This might void your warranty.
- It’s harder to do with laptops, and you’ll need a special case (disk enclosure) to put a hard drive in before connecting it to another machine.
- It is possible to infect the other computer if you open a file from the infected drive before scanning the drive with AVs and removing all found malware; or if all AVs fail to find and delete the malware.
- Restart the computer.
- Once you see a boot screen tap F8 key continuously until a list of options appears.
- Using arrow keys, select Safe Mode with Networking.
- Press Enter.
- Hold down Windows key
and hit X key. - Select Shut down or sign out.
- Press Shift key and click on Restart.
- When asked to choose an option, click on Advanced options => Startup Settings.
- Click Restart in the bottom right corner.
- After Windows reboots and offers you a list of options, press F5 to select Enable Safe Mode with Networking.
- Launch Shadow Explorer.
- On the top left part of the window you can select a disk (C:\, D:\, etc.) and a date when a snapshot of files was taken.
- To recover a file or a folder right-click on it and select Export’.
- Choose where do you want to put the files.
Going further, we need to 1) stop ransomware from encrypting files that we recover, if malware is still active; 2) try not to overwrite files deleted by ransomware. The best way to do it is disconnect your hard drive and connect it to another computer. You will be able to browse all your folders, scan them with antivirus programs, use file recovery software or restore data from Shadow Volume Copies. Although it is better to download all tools you’ll need beforehand and disconnect the computer from the Internet before connecting the infected hard drive, just to be safe.
Disadvantages of this method:
Another, easier, way is to load into Safe Mode and do all file recovery measures from there. However, that will mean using the hard drive and potentially overwriting some data. In this case it’s preferable to use only portable versions of recovery software (the ones that don’t require installation), download them onto an external device, and save any recovered files onto an external device too (external hard drive, thumb drive, CD, DVD, etc.).
Boot Into Safe Mode:
Windows XP, Windows Vista, Windows 7:
Windows XP, 
Windows Vista, 
Windows 7: Windows 8, Windows 8.1, Windows 10:

and hit X key.Back up Your Encrypted Files
It is alwayse advisable to create a copy of the encrypted files and put it away. That might help you if free ransomware decryptor becomes available in the future, or if you decide to pay and get the decryptor but something goes wrong and files get irreparably damaged in the process of decryption.

Attachments in spam emails are one of the most common ways ransomware ends up on users’ computers. MailWasher filters spam and lets you preview emails on a server without downloading them onto your computer. MailWasher has customizable spam filters, uses bayesian filtering and works with all major email programs: Outlook, Outlook Express, Thunderbird, GMail, etc.
Remove Yguekcbe Ransomware
Now that you have your recovered the files or at least stored the still encrypted files on an external device, it is time to scan your computer with AV and anti-malware software or, better yet, reinstall the operating system, to fully remove Yguekcbe ransomware and get rid of any possible traces. Remember to also scan your external device before putting files back on your computer!
