Uninstall UIWIX virus (Uninstall Instructions) - May 2017 updated

removal by Jake Doevan - - | Type: Ransomware

UIWIX ransomware is an example of fileless malware that infects computer systems using EternalBlue exploit

UIWIX virus is a dangerous ransomware program that attacks Windows operating system using the EternalBlue exploit. After gaining access to the target system, it encrypts files using AES-256 (CBC) and RC4 algorithms, adding ._[Victim’s ID].UIWIX file extensions to each filename. The virus then outputs a message from cyber criminals to _DECODE_FILES.txt file, which it saves on the desktop. Such ransom notes can be discovered in almost every folder that holds some encrypted files. The message from cyber criminals says that victim’s files were decoded and that the victim shouldn’t try to decrypt files using a third-party tool as this can result in permanent data loss. The virus provides several .onion URLs that point to a website that explains how to pay the ransom. The virus asks to pay $200 in Bitcoins, which is approximately 0.12126 BTC. IT security experts do not advise paying the ransom because it motivates cybercriminals to continue their evil activities and funds their future projects. Therefore, if your files were coded, better remove UIWIX using anti-malware programs like Reimage Reimage Cleaner Intego and take particular actions to protect yourself from ransomware attacks.

The functionality and attack vectors of UIWIX remind us of WannaCry ransomware, the infamous virus that managed to infect over 230,000 machines worldwide during the cyber attack that took place on May 12, 2017. Both viruses are designed to address Windows vulnerability in Server Message Block (SMB) using EternalBlue exploit that was disclosed by Shadow Brokers on April 14, 2017. It appears that the viruses only target Windows XP, 8, 2003 OS, therefore, computers running Windows 10 won’t be affected. The fileless ransomware doesn’t have a kill switch like WannaCryptor virus does, however, it also doesn’t have worm-like features to spread over the network by itself. What is more, experts have discovered that the new ransomware is designed to terminate itself in case it detects sandbox or virtual box environment, also if the victim is a resident of the following countries: Russian, Kazakhstan, and Belarus. If this virtual extortion tool managed to encrypt files on your system, you need to have a data backup in order to recreate the lost records. If you do not have a backup, you might start thinking about the option of paying the ransom. Remember that you might receive nothing in exchange. To fix your computer so that you could continue using it, follow UIWIX removal guidelines provided below the article.

UIWIX ransomware attack vectors

Microsoft provides two possible explanations for the spread of UIWIX ransomware. The giant company believes that the malicious file is distributed via social engineering emails designed to deceive computer user and convince them to open the malware. The second possible explanation says that computers can be infected through SMB exploit when a vulnerable computer is reachable from other infected computers. It appears that attackers exploited SMB EternalBlue vulnerability (code CVE-2017-0145), which was already patched by Microsoft in security bulletin MS17-010. However, users who use computers running targeted Windows operating systems can still be infected in case they did not install special updates issued by Microsoft. In this case, Microsoft released security updates for operating systems that are no longer supported.

Bonus: Restore your files

Using the tutorial provided above you should be able to eliminate UIWIX from the infected device. novirus.uk team has also prepared an in-depth data recovery guide which you will also find above.

Although WannaCry ransomware was defeated already, UIWIX is not developed by the same attackers and does not employ identical encryption methods to lock victim's files, therefore, there is no decryption tool for UIWIX available. We advise victims to use the following data recovery methods.

There are a couple of methods you can apply to recover data encrypted by UIWIX:

Recover some files locked by UIWIX using Data Recovery Pro

Test this data recovery software known as Data Recovery Pro. The tool already proved to be extremely useful when dealing with piles of corrupted data.

  • Download Data Recovery Pro;
  • Install Data Recovery on your computer following the steps indicated in the software’s Setup;
  • Run the program to scan your device for the data encrypted by UIWIX ransomware;
  • Recover the data.

Attempt to use Windows Previous Versions feature

This methods works only in case the system holds a copy of Windows Previous Version. If you created System Restore Point in the past, try this method.

  • Right-click on the encrypted document you want to recover;
  • Click “Properties” and navigate to “Previous versions” tab;
  • In the “Folder versions” section look for the available file copies. Choose the desired version and press “Restore”.

No free UIWIX decryption tools available

At the moment, the only decryptor for .UIWIX files is being sold by cyber extortionists for $200. We do not recommend purchasing this tool as it can be malicious itself. Please be patient and keep up with the latest news about the virus – security researchers might successfully defeat it the way they defeated WannaCry.

It is strongly recommended to take precautions and secure your computer from malware attacks. To protect your PC from UIWIX and other dangerous viruses, you should install and keep a powerful malware removal tool, for instance, Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes.

Prevent the government from spying on you

As there is a growing debate in government about collecting users' data and spying on citizens, you should take a closer look at this issue and find out what shady ways of gathering information can be used to collect information about you. You need to browse anonymously if you want to avoid any government-initiated spying and tracking of information. 

You can enjoy secure internet browsing and minimize the risk of intrusion into your system if you use Private Internet Access VPN program. This VPN application creates a virtual private network and provides access to the required data without any content restrictions.

Control government and other third party access to your data and ensure safe web browsing. Even if you do not engage in illegal activities and trust your ISP, we recommend being careful about your security. You should take extra precautions and start using a VPN program.

Reduce the threat of viruses by backing up your data

Due to their own careless behavior, computer users can suffer various losses caused by cyber infections. Viruses can affect the functionality of the software or directly corrupt data on your system by encrypting it. These problems can disrupt the system and cause you to lose personal data permanently. There is no such threat if you have the latest backups, as you can easily recover lost data and get back to work.

It is recommended to update the backups in parallel each time the system is modified. This way, you will be able to access the latest saved data after an unexpected virus attack or system failure. Backing up your files daily or weekly should become your habit.

By having the latest copies of important documents and projects, you will avoid serious inconveniences. File backups are especially useful if malware attacks your system unexpectedly. We recommend using the Data Recovery Pro program to restore the system.
