Malware may reinstall itself multiple times if you don't delete its core files. This may require tracking down dozens of files in different locations.
We recommend downloading Advanced System Repair to eradicate Malware for you (it should cut down the time to about 15 minutes).
What is RICKROLL LOCKER ransomware? And how does it execute its attack?
RICKROLL LOCKER ransomware is a file-locking malware that was discovered in the third week of January 2019. There’s not much information about the developers of this crypto-malware so it isn’t clear if it came from any popular ransomware groups. It uses the .cryptoid extension in marking the files it encrypts. The instant it execute its attack in the system, it drops the following malicious payload:
This malicious payload is the one that initiates the attack in the system and will connect it to a remote server managed by the attackers. It is also where RICKROLL LOCKER ransomware will download its components. These components are then placed on some system folders which help the crypto-malware in executing two modules namely, information gathering and stealth protection. The information gathering module is the one that digs out information from the system. The information gathered will then be used for the stealth protection module which uses it to scan the system for digital strings of various programs like sandbox environment, antivirus programs, and security programs. Once the crypto-malware finds these programs, it removes or disables them to prevent them from stopping its attack. It also makes modifications in the Windows Registry, affecting some registry keys and sub-keys and allows RICKROLL LOCKER ransomware to run automatically in every system startup.
RICKROLL LOCKER ransomware uses a sophisticated encryption algorithm in locking its targeted files. After the encryption, it adds the .cryptoid suffix to every affected file and drops the following ransom notes:
The ransom notes contain the following content:
SORRY! Your files are encrypted.
File contents are encrypted with random key.
Random key is encrypted with RSA public key (2048 bit).
We STRONGLY RECOMMEND you NOT to use any “decryption tools”.
These tools can damage your data, making recover IMPOSSIBLE.
AIso we recommend you not to contact data recovery companies.
They will just contact us, buy the key and sell it to you at a higher price.
If you want to decrypt your files, you have to get RSA private key.
In order to get private key, write here:
Attach file is 000000000.key from %appdata% to email message.
Without it we will not be able to decrypt your files

Bf someone else offers you files restoring, ask him for test decryption.
only we can successfully decrypt your files; knowing this can protect you from fraud.
You will receive instructions of what to do next.
How does RICKROLL LOCKER ransomware proliferate?
According to security experts, RICKROLL LOCKER ransomware proliferates using a malicious file that pretends to be a legitimate program or a game. And this file may be disseminated using these methods:
- Torrent downloads
- Key generator
- Portable version of a program
- Some kind of a license activator
As you can see, cyber criminals behind this crypto-malware use several tricks to infect users so you must be careful when you download any kind of file online.
