Complete .CR1 file virus removal guide
PureLocker or otherwise called .CR1 file virus is a new ransomware threat that operates by encrypting stored files and then demanding ransom payment for making them in their usual usable, accessible condition. It targets Windows, Linux and Mac users. For the encryption, it uses AES 256 + RSA 4096 encryption algorithm. The encrypted files will receive .CR1 extension name. After completing the encryption process, it creates YOUR_FILES.txt that explains users about the attack and instructs them that they need to pay a ransom to decrypt the files.
The amount of the ransom is not provided of the ransom note, although it asks users to contact the threat developers using [email protected] email address. They will provide the private key that help in restoring of the files. The note further states not to wait for a long since the key is available for only 7 days and if the contact is not made within this limited period, the last hope for the files recovery becomes deleted. Here is the complete text on the file:
All your files have been encrypted using: AES-256-CBC + RSA-4096.
Shadows copies were removed, original files were overwritten, renamed and deleted using safe methods.
Recovery is not possible without own RSA-4096 private key.
Only we can decrypt your files!
To decrypt your files contact us at: [email protected]
Your private key will be deleted after 7 days starting from: [date], after that the recovery of your files will not be possible.
Paying ransom fee to the scammers and then waiting for them that they will provide the decryption tool seem somewhat risky. These people may be frauds, and never send the promised software even after the payment is done. Instead, use some alternate option for the data recovery. For example, data recovery tool from third party can be an option to recover .CR1 file virus encrypted files, although the change is low. Existing backup, if there has been created before the files encryption, could be another. To find out more, check the recovery section provided below the post.
Know how the infection occur and way to avoid it
Ransomware viruses are mostly distributed via using spam email campaigns. Cybercriminals design spam emails having some infectious files on them. Short messages convince recipients into clicking such file attachments. If done, the users are asked to enable macros command. One more click leads them into downloading/installing malware. Thus, it becomes necessary to be careful when receiving any emails. At least check senders’ addresses. In case of any doubt, avoid opening them.
Other sources that could cause ransomware infection include untrustworthy downloading channels, fake software updaters and cracking tools. Untrustworthy downloading channels include free file hosting sites, p2p networks and third party downloaders/installers offer rogue applications. The fake software updaters/cracking tools infect computers by supposedly updating/activating software. Use official sources for software download/install and update and avoid using any cracking tools for activating any paid software.
Remove .CR1 file virus
Ransomware viruses could have additionally attached modules to run a sequence of malicious tasks before encrypting files, appending them and creating ransom note. They can target system process and inject malicious entries on them to make the system start misbehave. Keeping them longer inside PC can cause other files encryption that are left unencrypted as well. They can enable shell command and delete Shadow Volume Copy or other backup that could be an option for data recovery.
Further, the viruses can target stealing stored personal data and injecting other malicious malware. Thus, you are highly recommended .CR1 file virus from the system without wasting much time and even before thinking about files retrieval (since this becomes possible only after the threat removal). Use manual or automatic mode for the malware removal as of your PC. The step by step instructions for the both are provided for you.

Using inbuilt system recovery services, the backup can restore the files which are included under the backup. This method is considered easier as well and leaves no software, thus considered as a very popular method to fight against emergencies caused by infectious malware. Here are the steps to follow:
