CryptoLuck virus Removal Guide
Description of CryptoLuck ransomware virus
The characteristics of CryptoLuck ransomware virus
CryptoLuck virus, also known as Luck, belongs to file-encrypting virus category. Ransomware type viruses are created to damage computer users’ personal files and demand paying the ransom. This malware uses advanced infiltration techniques to get inside computers and encrypts files using strong AES and RSA algorithms. To the encoded data it appends .[victim_id]_luck file extension which allows victims to distinguish corrupted files from the safe ones. However, it’s doubtful that you will find lots of free files because CryptoLuck ransomware targets the most popular file types such as MS Office, various audio, video or picture files. After successful data encryption, the malware change desktop’s wallpaper and drops a ransom note called @WARNING_FILES_ARE_ENCRYPTED.[victim_id].txt. The ransom note includes necessary information about data decryption and shows the Decryption Wizard. Victims have to pay 2.1 Bitcoin ransom within 72 hours and the wizard is supposed to restore all files automatically. After the deadline, the unique decryption key will be deleted, and victims lose their possibility to get back their files. It may be true; however, we recommend trying additional data recovery methods instead. Before looking for alternative ways to restore files, you have to remove CryptoLuck from the computer. For this task employ FortectIntego or other strong antivirus program and scan computer’s system. Keep in mind that virus may block access to the security tools, so you should check our prepared instructions at the end of the article.
However, some users may not see the Decryption Wizard window. This statement is noted in the ransom note. Then hackers suggest users disabling Firewalls and antivirus programs. This gives us a feeling that CryptoLuck removal is not a hard task for malware removal tools. However, the virus seems familiar to other well-known viruses – CryptoLocker and Locky. Malware drops almost identical ransom note and desktop picture like CryptoLocker; the only difference is the payment size and the title of the ransom note. Talking about malware distribution techniques, CryptoLuck ransomware seems similar to the Locky virus. Both of them uses RIG exploit kit to get inside the computers.
Malware distribution strategies
As we already told you, one of the malware distribution techniques are RIG-E (Empire) exploit kit. This tool is spread via malicious ads placed on compromised websites such as adult-themed sites. Computers are infected when users click on malware-laden ad – then the malicious file is dropped straight into the system and starts damaging files. However, it’s not the only way how CryptoLuck virus is distributed. It may also affect computers using legitimate GoogleUpdate.exe files and DLL hijacking. The latter methods allow spreading malware in the wider range. Cyber security specialists noticed an increase in successful ransomware attacks and remind users to stay safe online. Protecting computer with a reputable antivirus program will decrease the possibility of the attack. However, the more concerns are about data protection. It’s crucial to make data backups regularly and store them in external devices. Users, who have data backups, do not need to worry about data recovery and they do not even consider paying the ransom for cyber criminals. Ransomware attacks always are unexpected, so you should be prepared for the worst.

How to prevent from getting ransomware
A proper web browser and VPN tool can guarantee better safety
As online spying becomes an increasing problem, people are becoming more interested in how to protect their privacy. One way to increase your online security is to choose the most secure and private web browser. But if you want complete anonymity and security when surfing the web, you need Private Internet Access VPN service. This tool successfully reroutes traffic across different servers, so your IP address and location remain protected. It is also important that this tool is based on a strict no-log policy, so no data is collected and cannot be leaked or made available to first or third parties. If you want to feel safe on the internet, a combination of a secure web browser and a Private Internet Access VPN will help you.
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. 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.
