Buyunlockcode Virus

Buyunlockcode Virus is a ransomware application that spreads through Trojans and various exploits. It is a very dangerous and disturbing infection because it virtually destroys your files, and there is nothing you can do about it. There is also no way to remove Buyunlockcode Virus from your computer because this application deletes itself once the payload is delivered. The best way to avoid this infection is to stay away from unfamiliar websites and avoid opening spam email attachments. Buyunlockcode Virus is a computer infection that should not be taken lightly.

This program comes from the same group as CryptoLocker, Cryptorbit, and other infections that encrypt user files. Usually, ransomware programs deny desktop access by pretending they are related to law enforcement authorities. For example, the Ukash family ransomware programs maintain that users have committed criminal cyber activity, and so their computers have been locked. However, Buyunlockcode Virus does nothing of the sort. This application enters your computer like a criminal and behaves like one. It does not even need to hold your computer hostage.

As mentioned above, Buyunlockcode Virus usually gets distributed in spam email attachments. Never open attachments you find in random email messages from unknown senders. Even if the sender is someone you know, do not download the attachment if the email messages seem rather random. The Trojan that distributes Buyunlockcode Virus might have infected your friend’s email account, and thus found its way to you.

When you download the Trojan on your computer and run it, Buyunlockcode Virus gets installed on your system. Once you are infected, the malware will scan your computer, and it will encrypt all the data files it detects. Buyunlockcode Virus can encrypt over seventy file extensions, so you can be sure that your most important files will be encrypted if you get infected with this program.

This ransomware program encrypts your files with AES encryption. It also uses a key that unlocks the aforementioned encryption with the RSA key. In every single folder that contains encrypted files, you will find a Buyunlockcode.txt file. This file contains information on how to obtain the decryption key for your files. In other words, Buyunlockcode Virus wants you to pay in order to regain your files.

There have been reports that the malware creators do issue a decryption key once users send them a particular sum of money, but you have to realize that by doing so you would help cyber criminals reach their goals.

In order to avoid similar problems, you should always keep a file back-up, whether it would be on a cloud drive or in an external hard disk. Also, you should consider running regular system scans with a licensed antispyware tool. What is more, do not hesitate to scan any email attachments with a security program of choice because you can never know whether the next file you download is Buyunlockcode Virus.
