CryptoLocker 5.1 virus Removal Guide
Description of CryptoLocker 5.1 ransomware virus
Important information about CryptoLocker 5.1 ransomware virus
CryptoLocker 5.1 virus pretends to be a member of CryptoLocker family by borrowing the well-known virus’ name and file extension. The new file-encrypting virus does not differ from other ransomware viruses; it operates and spreads similarly. When the victim opens an infected email attachment, the virus gets inside and starts encoding lots of different types of files located on the computer. It uses strong RSA-2048 algorithm and appends .locked file extension. When data encryption is over, victims cannot open any of their documents. According to the crooks, corrupted files will remain damaged forever, if victims do not pay the ransom within 48 hours. Cyber criminals beware that computer users are scared of losing their important files, and only a few of them make backup copies regularly. For this reason, many users are willing to pay a huge sum of money for the possibility to recover lost files. If you became a victim of CryptoLocker 5.1 ransomware, we advise you not to pay the money. Chances that they give you a necessary decryption key are small. Usually, hackers disappear after receiving the money, because the primary goal of the ransomware is to swindle money from the computer users. Instead of risking your money, you should remove CryptoLocker 5.1 from your system. Virus elimination does not recover lost files, but after removal, you will be able to use additional methods to decrypt at least some of your data.
It seems that CryptoLocker 5.1 virus targets Italians mostly because it leaves a ransom note in the Italian language. Once ransomware completes file encryption process, it drops a ransom note called LEGGI.txt and delivers a pop-up window which includes unique ID, timer, and important information about data encryption and decryption. In the pop-up window, hackers explain victims that all their files were encoded and they can get them back only if they pay the ransom. They have to pay €130-250 in two days and contact criminals via provided email address: firstname.lastname@example.org. Within day or two hackers respond with a necessary decryption key. Victims have to hurry up and make the decision quickly because when the time runs out, file decryption key will be deleted and the possibility to recover lost data will be gone forever. Indeed, at the moment there are no free decryption tools available, but we do not recommend paying the ransom. Scan your computer with ReimageIntego, SpyHunter 5Combo Cleaner or other anti-malware program and initiate CryptoLocker 5.1 removal. As we already mentioned, hackers might disappear after receiving the money, but the virus stays. Malware makes your computer vulnerable and might let other computer infections get inside. Therefore, it’s important to remove the virus and later think about data recovery.
How does malware spread?
CryptoLocker 5.1 ransomware spreads via malicious email attachments. Cyber criminals launch various persuasive spam email campaigns and trick users to open the attached PDF file. They find numerous reasons to trick users that the document is safe and important. Usually, an infected file is named as invoice, receipt or financial report. It’s hard to believe that bank, financial institution, governmental organisation or other reputable company might send a virus. Unfortunately, nowadays computer users have to doubt everything they see and receive online. Any link, advertisement or email attachment might include CryptoLocker 5.1 malware or another file-encrypting virus. Before opening any email attachment from the unknown sender, double check the information. Hackers might copy even the design of an official website, so you can never be sure if you can trust the sender.
CryptoLocker 5.1 removal suggestions
Ransomware is one of the most hazardous computer infections, so their elimination should be held using powerful and professional tools.

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.
Recover files damaged by a dangerous malware attack
Despite the fact that there are various circumstances that can cause data to be lost on a system, including accidental deletion, the most common reason people lose photos, documents, videos, and other important data is the infection of malware.
Some malicious programs can delete files and prevent the software from running smoothly. However, there is a greater threat from the dangerous viruses that can encrypt documents, system files, and images. Ransomware-type viruses focus on encrypting data and restricting users’ access to files, so you can permanently lose personal data when you download such a virus to your computer.
The ability to unlock encrypted files is very limited, but some programs have a data recovery feature. In some cases, the Data Recovery Pro program can help recover at least some of the data that has been locked by a virus or other cyber infection.
