YOUR_LAST_CHANCE ransomware removal instructions
What is YOUR_LAST_CHANCE?
First discovered by malware researcher, GrujaRS, YOUR_LAST_CHANCE is an updated variant of high-risk ransomware called Nemesis. As with its predecessor, YOUR_LAST_CHANCE encrypts most stored files and renames them. This variant appends filenames with the victim's unique ID and ".YOUR_LAST_CHANCE" extension (hence the ransomware's name). For example, "sample.jpg" might be renamed to a filename such as "sample.jpg.id_3057868259_.YOUR_LAST_CHANCE". Additionally, YOUR_LAST_CHANCE automatically opens a temporary text file ("temp000000.txt") and generates another text file called "_RESTORE FILES_.txt" and stores a copy in every existing folder.
The new text file delivers a ransom-demand message stating that files are encrypted and that victims must purchase a decryption tool to restore them. Unfortunately, statements suggesting that only developers of YOUR_LAST_CHANCE are capable of restoring data are accurate. It is currently unknown whether YOUR_LAST_CHANCE uses symmetric or asymmetric cryptography, however, each victim gets a unique decryption tool, which is necessary to restore data. All keys are stored on a remote server controlled by cyber criminals. Therefore, these people can blackmail victims by offering a paid recovery of files. The cost of YOUR_LAST_CHANCE data decryption is currently unknown, however, cyber criminals typically demand $500-$1500 in Bitcoins, Monero, Dash, or another cryptocurrency. No matter what the cost, do not pay. Ransomware developers often ignore victims once payments are submitted. Therefore, paying delivers no positive result and users are scammed. We strongly recommend that you ignore all requests to contact these people or pay any ransoms.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
YOUR_LAST_CHANCE is virtually identical to dozens of other ransomware infections, such as Lokas, Boooam, and CAGO. All encrypt data so that developers are able to make ransom demands. Be aware that encryptions are often performed using algorithms that generate unique decryption keys (e.g., RSA, AES, and similar). Therefore, unless the malware has flaws or bugs, restoring data manually (without developers' involvement) is impossible. Bear in mind that locally stored backups are compromised together with regular data. Therefore, we strongly advise you to store them on a remote server or unplugged storage device. There is always the chance that servers/storage devices can be damaged and, therefore, have multiple backup copies stored in different locations.
How did ransomware infect my computer?
In most cases, ransomware infections are distributed using fake software updaters and 'cracks', trojans, unofficial software download sources, and spam email campaigns. Fake updaters typically infect computers by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than updates. The same applies to software cracks, which infect computers rather than activating paid software free of charge. Trojans are essentially malicious applications that stealthily infiltrate computers to cause "chain infections" - they inject additional malware into the system. Cyber criminals use third party download sources such as freeware download websites, free file hosting sites, Peer-to-Peer (P2P) networks, and others to proliferate malware by presenting it as legitimate software. In this way, criminals trick users to manually download and install malware. Spam email campaigns are also used in a similar manner. Criminals send hundreds of thousands of emails that contain deceptive messages encouraging recipients to open malicious attachments (links/files), which are typically presented as 'important documents'. In summary, the main reasons for computer infections are poor knowledge of these threats and careless behavior.

|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads.|
|Damage||All files are encrypted and cannot be opened without paying a ransom. Additional password-stealing trojans and malware infections can be installed together with a ransomware infection.|

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.
How to protect yourself from ransomware infections?
The key to computer safety is caution. Therefore, pay attention when browsing the Internet and downloading/installing/updating software. All received email attachments should be handled with care. Attachments that are irrelevant and those received from suspicious/unrecognizable email addresses should never be opened. Download software from official sources only, preferably using direct download links. Remember that third party downloaders/installers usually include rogue apps, and thus such tools should never be used. Proper software maintenance is also extremely important. Keep installed applications/operating systems up-to-date, however, use only implemented functions or tools provided by the official developer. Software piracy is a cyber crime, and since most cracking tools are fake, the risk of infections is very high. Therefore, never attempt to activate software using third party tools. Finally, have legitimate anti-virus software installed and running, since these programs protect the system from malware and detect and eliminate infections before the system is harmed. If your computer is already infected with YOUR_LAST_CHANCE, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the YOUR_LAST_CHANCE ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining YOUR_LAST_CHANCE ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of YOUR_LAST_CHANCE are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as YOUR_LAST_CHANCE ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
