If any or all of the data files on your computer have gotten locked and you are told you must pay a ransom to regain your access to those files, then you have certainly become victim of Ransomware. As you have probably heard, Ransomware is a very widespread, and very problematic category of malicious programs. The main goal of its representatives is to allow the hackers behind them to blackmail the attacked users by keeping their files inaccessible until a certain amount of money gets paid. This is how Ransomware infections work, and if you have been attacked by one, make sure to carefully read the next lines.
The .Cetori virus – typical traits
Cetori is a new piece of malware that belongs to the Ransomware cryptovirus category (Masodas, Vesrato). It uses its advanced data encryptions to make the files of its targets inaccessible without the application of the corresponding unique decryption key. That key is kept on the hackers’ servers, and is promised to the users who pay the demanded ransom sum. The problem with the ransom payment, aside from it being quite costly most of the time, is that the user doesn’t get any guarantee that their files would indeed get released in the end. Some hackers offer to restore a file or two for free in order to convince their victims that they have a working decryption solution. However, even if the criminals do indeed have a decryption key, you can’t be sure that it will get sent to you once you pay. There are more than enough examples where the payment of the ransom from the user’s side didn’t result in the sending of the decryption key by the hackers. Considering how risky this all is, and also considering the fact that the required sum can oftentimes be quite sizeable, we advise you to first try other methods of dealing with this issue before you even think about paying.
The .Cetori file lockdown – solutions?
Sadly, we cannot offer you a surefire solution that will release all of your files with a hundred percent effectiveness, and that would work in all cases. Instead, the goal here is to try different things and minimize the negative consequences of the malware attack. In some cases, this might mean getting all of your files back, while in others it may be limited to removing the virus.
The removal of Cetori is actually where you should start, no matter what alternative recovery method you want to try to use next. Below, you will find our Cetori removal guide, and you are advised to follow its instructions in order to get rid of the nefarious threat. After the malware is no longer inside your computer, you should visit the second section of the guide, which is focused on recovery. Try the suggestions there, and see if they work for you. Also, do not forget to check all your other devices and cloud services (if you use any) for any forgotten copies of the files that the Ransomware has locked in your computer – you may get lucky and find that some of your important files are still accessible on those other devices/cloud storages.
