What is btCry_zip ransomware?

btCry_zip is another variant of dangerous ransomware called Xorist, that was created with the purpose of blackmailing people. Immediately after infiltration, it runs its malicious processes and starts the encryption procedure. It uses the AES encryption algorithm to encipher all victim’s data so that these files can not be used or accessed until they are decrypted. The decryption key may unlock all the data and that is exactly why cyber criminals will offer their deal – money in exchange for the decryption key. The cost of decryption may be terrifically huge. If you got this virus on your computer, you may use our tutorial in order to remove btCry_zip ransomware and try to decrypt .btCry_zip files without paying a ransom.

As we mentioned earlier, the virus affects data in such a way so you won’t be able to open files with .btCry_zip extension unless they are decrypted. For example, file “IMG_2462.PNG” will turn into “IMG_2462.PNG.btCry_zip”. Afterward, btCry_zip ransomware drops a TXT file (HOW TO DECRYPT FILES.txt) that contains the same text:

How to prevent your system from Ransomware?

No one is safe from infection with a virus that secretly encrypts your data. But in order to minimize this risk, you need to follow the rules:

1. Always make Windows updates on time and keep them up to date. Remember that these updates close the security holes of the system through which the virus can enter your computer.

2. The most efficient way to avoid data loss is of course to make a backup of all important data from your computer. It is enough just to synchronize the necessary folders with one of the cloud services, so as not to be afraid to see the text requiring the payment of bitcoins in exchange for a decryption key. It can be a cloud or a remote hard drive on the network. If you store all your files on the Internet, the likelihood of virus infection will be lower. Do not make copies to external hard drives, as this could damage them.

3. Since spam email is the most popular form of spreading ransomware-type viruses, the user should never open email attachments without first having scanned them with antivirus. Just clicking on the link or opening the attachment can damage the operating system (Windows) in a few minutes, damage important data and infect other machines with the virus.

4. All previous methods do not matter if you do not have a reliable antivirus. The presence of anti-virus protection on your computer can prevent all these unpleasant surprises. Anti-virus protection will protect you from malware, money loss, time loss, invasion of your personal life. Now the antivirus protection is so huge that it is difficult to make a choice in favor of one of them. If you have not decided who to give preference to, we suggest you familiarize with our Top 5 Antivirus Software for Windows
