Ox4444 ransomware removal instructions
What is Ox4444?
Ox4444 is a high-risk virus that is categorized as ransomware. It is a new variant of a high-risk malware called GlobeImposter. Once a computer gets infected with Ox4444, this virus encrypts all (or most) files and makes them unusable. Ox4444 adds the ".Ox4444" extension to every encrypted file. In other words, it renames every encrypted. For example: "sample.jpg" is renamed to "sample.jpg.Ox4444" and so on. Ox4444 ransomware also puts a "HOW_TO_BACK_FILES.txt" text file in folders that contain encrypted files.
"HOW_TO_BACK_FILES.txt" text file is a ransom-demanding message that contains information how to contact Ox4444 developers (cyber criminals). According to it, victims of the Ox4444 virus must contact cyber criminals via one of the provided emails (China.Helper@aol.com or China.Helper@india.com) and provide their personal ID. Once a victim is identified, Ox4444 developers will decrypt some files for free and then the price of the decryption of all the other files will be defined as well. Crooks use a free decryption as an evidence that they can be trusted. According to cyber criminals, their victims will receive a decryption tool as soon as the ransom demands are met. They also inform people that they are the only ones who can decrypt the encrypted files and urge their victims to do not try to decrypt the files manually. It is unknown what cryptography algorithm (symmetric or asymmetric) Ox4444 developers use to encrypt data, however, there is no tool that could be capable of cracking Ox4444 encryption for free. It is not recommended to contact cyber criminals because usually they cannot be trusted. Very often they ignore their victims even when the payment is made. The only way to retrieve the files for free is to use an existing backup.
Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data:
Most ransomware-type viruses are very similar, some examples of other viruses of this type are Dharma-tron, Maria, Xxxxx, Sicck and Gdb. As a rule, these viruses are designed to encrypt the files and to make ransom demands. Most common variables are the cryptography algorithm used to encrypt the files and the amount of the money (ransom size) required for the decryption. As a rule, manual decryption is impossible, unless the virus has some bugs, flaws, or it is not completely developed. In other cases people are forced to contact cyber criminals. For this reason we recommend to maintain regular backups and to keep them in some remote server or unplugged storage device. If not, then ransomware virus probably will encrypt the backup together with other data.
How did ransomware infect my computer?
It is hard to tell what was the exact reason of this infection, however, there are several most common ways to get a computer infected with ransomware. Ransomware-type viruses usually are proliferated using email spam campaigns, untrustworthy third party software download sources, trojans and fake updaters. Email spam campaigns are used to proliferate these (and other) viruses by presenting malicious email attachments as legitimate. The purpose of email spam campaigns is to trick people into opening malicious attachments. These attachments usually are Microsoft Office documents (Word, Excel etc), executable files (.exe), archive files (RAR and similar) and so on. Once opened, attachments are given a permission to download/install malware and infect computers. Various third party download sources such as peer-to-peer networks, freeware download websites, free file hosting websites, torrents and so on are often used to present malicious executables as legitimate files. These sources often are used to trick people into installing malware and various viruses by themselves. Trojans are designed to proliferate other viruses. Simply said, if a trojan is installed, then most likely that it will infect computers with other viruses as well. Fake software updaters usually infect systems by exploiting outdated software's bugs and flaws, or by simply downloading malware instead of the promised updates.
How to protect yourself from ransomware infections?
Take precautions when dealing with emails, avoid opening attachments or links that are presented in emails sent from unknown/suspicious addresses. If you suspect that an email is irrelevant, do not open the included attachment or click presented link. Download software using direct links, trustworthy, official channels only. Avoid using various third party downloaders, installers. These sources often are used to proliferate various rogue applications that might cause computer infections or other problems. Update software using tools or implemented functions that are provided by official software developers. Do not use various third party updaters for that. And finally, have a reputable anti-virus/anti-spyware installed and keep it enabled at all times. Such software usually helps to prevent viruses from being spread and do any harm. If your computer is already infected with Ox4444, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Ox4444 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 Ox4444 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 Ox4444 ransomware.
