A craw virus or .craw file is a computer infection that was developed by cyber attackers to extort money from its victims. It encodes all important files and demands to pay a ransom in exchange for the decryption tool.
This page contains details of what Craw Ransomware Virus is all about. It explains how did craw virus install on the computer, how to prevent it, and way to save the system from this cyber attack.
Craw virus is another version of a known ransomware virus called STOP. It uses AES/RSA ciphers to encrypt all valuable and personal files on an infected computer. Then it appends .craw extension to all encrypted files. While Craw is bugging the system, images, videos, documents, audio files, and more will become unusable.
Then a _readme.txt or called as a ransom note will be placed on the victim’s desktop. It encloses information about what happened to your files. Craw virus states that personal and important data are encrypted with the strongest encryption and unique key. To decrypt it, victims have to pay $490-$980. The ransom amount is depending on how fast a victim will contact malware authors.
Craw virus insists that aside from paying the ransom, there is no other way to decrypt all encoded files. It provides an email address in which the victim can contact cyber attackers. We strongly suggest not paying the ransom or not even dealing with malware author.
About encrypted files, the best option to recover it is through backup data. Be warned that paying for ransom will not resolve the issue. Once you give the amount required, there is no guarantee that cyber crook will send back the private key and decrypt software.
Packed programs, freeware, and shareware applications can drop Craw ransomware into the computer. A malicious item like Craw virus may include on the installation process through Default settings. Thus, to avoid unwanted software from installing on the computer, a user must select Advanced or Custom settings. Then remove the checkmark on boxes to exclude suspicious or unknown applications.
If you installed Craw ransomware inadvertently, you have to remove the virus infection as soon as possible. After removal of Craw, it is vital to perform a full system scan with a trusted and effective anti-malware program.
We highly suggested keeping a reputable security software installed on the computer to obstruct any malicious code that trying to invade the system.
