CryptoLocker 5.1 virus Removal Guide

What is CryptoLocker 5.1 ransomware virus?

CryptoLocker 5.1 ransomware starts its cyber campaign

CryptoLocker 5.1 virus might cause associations with the notorious CryptoLocker ransomware family. Indeed, its ransomware message has resemblances to the original threat. For example, it attaches .locked extension to the affected files. However, specialists are convinced that it is only an imitation disguised under the name of the mentioned virus. Moreover, it has gained alternative title – Il tuo computer e stato infettato da Cryptolocker! virus. It presents the requirements in the ransom note written in the Italian language. The authors try to terrify the victims with this menace and require transferring the money within 48 hours to retrieve the files. Needless to say that it is a common strategy to threaten users. You should not consider doing this. Instead, your current priority should be CryptoLocker 5.1 removal. For that purpose, you can employ an anti-spyware application to speed up the elimination. In the last section of the article, you will not only find the instructions how to remove CryptoLocker 5.1 properly but how to perform file recovery as well.

The ransom note of CryptoLocker 5.1

When the notorious cyber threat Crypto Locker hit the stage a couple of years ago, its appearance not only caused great data and financial losses for ordinary users but it left an inspiration for wannabe hackers. Unfortunately, crooks, who often happen to be high school boys, learn quickly from their mistakes and exploit their talent for programming viruses. Thus, it was only a matter of time when the notorious ransomware will be accompanied by numerous different “offsprings.” Since the original version has managed to wheedle out stunning amounts of money, the creators of this threat were also inspired to earn delicate amounts of money. Following the tradition of ransomware, CryptoLocker 5.1 malware demands 250€. The transaction should be made within 48 hours. Otherwise, the cyber criminals threaten to delete the files permanently. Alarmed by such scenario, victims rush to pay the money within the specified period of time. However, the thing is that neither they nor you cannot be sure that the files will be transferred even after remitting the payment. The crooks are not obliged to keep their word. Returning the files purely depends on their sense of conscience. Thus, eliminate the threat with FortectIntego.

When did the malware infiltrate the computer?

It is not surprising if Crypto Locker 5.1 ransomware used a spam email to get into the device. As with the previous versions of original CryptoLocker, the current virus tends to spread via spam emails in the disguise of a pdf file. Unfortunately, even now such technique proves to be highly profitable as users are not careful enough reviewing their spam messages. The crooks have manifested their creativity by disguising the executables within the invoice or fake financial reports. Thus, without any suspicion, the users open the attached file only to find out that they activated the real cyber threat. If you committed the same mistake, keep in mind that you should remain vigilant even if you receive the email from the supposed FBI or local tax institutions. It is wise to double-check the sender before making any reckless actions which later cost not only time and nerves but money as well.

CryptoLocker 5.1 elimination steps

Even if it is not the original version of the computer menace we do not recommend you to take the threat too lightly. Therefore, eliminating the virus with an anti-spyware application, such as FortectIntego or Malwarebytes, would be a better solution. The software will deal with the threat completely without leaving any of its files. However, either of these programs is not capable of decrypting the files. Therefore, you will need to restore the files from a backup or use of the alternative methods. Take a look at our suggestions as they might be of great use for you.

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
