How to remove (uninstall) AiraCrop

Ransomware are the most dangerous viruses that can be found online. There are many different unwanted and malicious software, but ransomware cause most inconvenience, cause the greatest damage and its consequences are the most difficult to neutralize. To cope with ransomware, you will need to wait for the experts from renowned companies find a way to crack the code of a virus, or have access to its command centers. In the case of AiraCrop - the virus was discovered recently, and work on its breaking is in the middle.

What is AiraCrop

AiraCrop has all the usual signs of ransomware. This is a malicious program that penetrates the user's computer via spam e-mail. Such reports often come in the name of the famous companies engaged in cargo transportation, large stores or online stores. The letters mean that on the user's name came the parcel or, on the contrary, there was an error, and they cannot deliver the goods to the addressee. To solve the problem, you are prompted to print a form that is attached to the letter and to come to the nearest office of the company. If you believe in what is written, and try to open the attachment - you get a virus.

After penetration AiraCrop begins to act immediately. The virus enters the system, and sets the task to run at the next boot of Windows. When the user turns on or restarts the computer next time - AiraCrop immediately starts searching and encryption. In fact, the list of file extensions that ransomware can encrypt is very large, but 99% of users use the files in 5-10 different extensions, such as .txt, .jpg, .png, .bmp, .xlsx, .PDF, .jpeg and other . First, the virus searches for these files and encrypts them in the first place. After that it encrypts other files. Only the program files remain untouched. Once the encryption process is completed, the victim receives a message that appears on his desktop. The message says that all the files on a computer were encrypted, and indicates the amount of redemption and payment methods. While encrypting files, the virus adds the ._AiraCropEncrypted extension to filenames.

AiraCrop uses two encryption algorithms for file protection. First, the user’s files are encrypted using asymmetric encryption with AES-256 algorithm. Then, the key from the first encryption is being encrypted using the RSA algorithm. Ransomware viruses are so dangerous because such encryption is virtually impossible to break, and therefore we should rely on the breaking of hacker’s C&C center or the ransomware’s program code.

Currently there is no information on whether it is possible to restore files encrypted by AiraCrop ransomware. We strongly recommend all users confronted with the virus not to pay the ransom. There is no guarantee of data decryption when the scammers will receive the money. The best solution is to completely clean your computer from the virus, and to wait until a decent ._AiraCropEncrypted files decryptor will be developed.
