Ransomware infections are becoming more and more popular and even the regular online users are getting familiar with them. The reason is, there are some massive Ransomware attacks happening these days and all the news headlines are filled with shocking titles about the devastating effects of these threats on the victims’ machines. The number of new and more sophisticated infections of this type is growing rapidly with each year and Ransomware has quickly become a real global threat. One of the many new Ransomware variants is called .Cpt – a cryptovirus, created to blackmail unsuspecting online users by encrypting their files and asking them to pay ransom. The cyber criminals, who support this infection, use a very simple scheme, with the help of which they can extort money from you – they take your most valuable files hostage and keep them encrypted unless you fulfill their demands. Victims of this new blackmail scheme are not only regular users but also institutions, governments, big businesses, hospitals, schools, banks and more. Being infected with a threat like .Cpt may lead to huge financial losses, as well as the loss of entire databases. In the text below, we will tell you more about the way Ransomware operates, as well as some alternatives, which may help you avoid the ransom payment. At the end of the page, you will also find a guide that can help you remove .Cpt and some file-restoration instructions that may get some of your data back to normal.

How can Ransomware infect you and remain undetected?

Probably the most dreadful ability of Ransomware is its ability to infect your system in such a way, that you may not even know about it. The authors of such malware often distribute it via spam, Trojans, malvertisements or other, seemingly harmless malicious transmitters. What is more, they program it in such a way that it may often pass by most antivirus programs without being detected, which helps it complete its file-encrypting task without any interruption.

How to Decrypt .Cpt files

We have a comprehensive (and daily updated) guide on how to decrypt your files. Check it out here.

If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!

Threats like .Cpt , for instance, are experts in this. They use advanced techniques to infiltrate the computer, remain unnoticed and secretly apply very complex cryptography to all the files that can be found inside. The result of the encryption is that the victim cannot open or use the affected data in any way unless they pay the hackers for a decryption key. This blackmail scheme turns out to be very profitable in criminal circles that extort millions of dollars from their victims with the help of this malware.

What makes dealing with Ransomware very difficult is the fact that it is not always possible to recover the files from the malicious encryption, even if you strictly fulfill all the ransom demands. The process of encryption is a very delicate process, which may not always be flawlessly reversed, more so because of its complexity, which even the hackers may not be able to handle successfully. In fact, what the criminals want is just to get the files encrypted and blackmail you. Decrypting them is none of their business the moment they get the money. That’s why it is very common that the decryption keys they send to their victims may not work. What is more, by keeping the Ransomware inside your computer instead of removing it, your system is heavily compromised and is not safe to use.

What other options do you have?

In the beginning of this article, we mentioned a removal guide, which you can freely use to detect and remove .Cpt from your computer. Regardless of what you decide to do about the ransom payment, we strongly encourage you to use the instructions and remove the Ransomware. This will clean your PC form the infection and will make it safe to use further. If your images, documents, files, programs, projects, and similar sort of useful data have been encrypted by .Cpt , there is an alternative way to save them from your own file backups. Check your external drive, cloud storage and other devices for some copies. If you don’t have backups, very few things can help you. However, the removal guide below contains some file-restoration instructions that may potentially help you save some of your data. They may not work flawlessly, but it is definitely worth giving them a try. Another option is to seek for a free decryptor tool. A list of daily updated free descriptors you can find on our website. In some cases, these tools may help you reverse the malicious encryption and release your data, but again, there is no guarantee for anything. The most important thing is to be realistic about your recovery expectations and use your common sense when choosing how to deal with the Ransomware.
