If you get attacked by a Ransomware cryptovirus this could deprive you of accessing your most important files. Your documents, archives, databases, images, videos, audios and other commonly used files may suddenly become encrypted with a secret algorithm, which renders them inaccessible. No matter what you try to do, you will not be able to open or use any of your files without paying a certain amount of money to the hackers who are keeping the corresponding decryption key. This is exactly what can happen if your system has been compromised by one of the latest Ransomware infections called Nasoh. This threat is designed to blackmail random web users, businesses and even big governmental institutions and to extort money from them in  order to restore the encrypted files to their previous state.

The attackers, who stay behind the infection, typically generate a ransom-demanding notification on the screen of the infected machine immediately after the secret encryption process has completed. The victims usually get scared and quite shocked to detect such a message on their monitor and don’t know what to do. If you have recently been greeted by a notification that asks you to pay a certain amount of money to a given cryptocurrency wallet, you may well be feeling frustrated and you may be searching for a highly effective course of action that can help you avoid the ransom payment. Fortunately, on this page, we are happy to provide you with some alternative methods which may help you to remove Nasoh and potentially recover your encrypted files.

Compared to other malware types, computer infections like Nasoh, Coharos or Mtogas have a great advantage – they are extremely stealthy and may oftentimes remain under the radar of most antivirus programs. This is because, instead of causing some real system damage, which can be detected by the security software, the Ransomware threats use file-encryption as a foundation to their blackmail scheme, which is actually not a harmful process. File encryption is a common process for the system since we need it to keep sensitive information safe and protected from unauthorized access. We use encryption on a day-to-day basis when searching the Internet, when paying online, when using our e-banking, when chatting, etc. For this reason, most of the antivirus programs on the market do not consider the encryption as something unusual or malicious, and they normally do nothing to stop it. This helps the Ransomware to apply its encryption without any disturbance and then surprise us with a threatening ransom-demanding notification when it is finished.

The .Nasoh file-encryption goal

The goal of Nasoh and its terrible blackmail scheme is to extort money from as many people as possible. The crooks behind the scheme may use different threatening scenarios in order to make the victims pay as fast as possible. They may even promise to send a special decryption key immediately after the payment is made. Some crooks may go as far as giving you to test-decrypt a file or two, just to make you believe them. If you pay, however, you will basically be sponsoring the criminals to create more Ransomware and infect more users with it. Not to mention that there is nothing that could make them fulfill their promise and you may never receive any decryption solution in return for your money.

For this reason, we typically advise the people who land on our “How to remove” guide to seek alternative options of dealing with the Ransomware, before choosing the ransom transaction. One such option is the Removal Guide below.

7: Nasoh Decryption

The previous steps were all aimed at removing the Nasoh Ransomware from your PC. However, in order to regain access to your files, you will also need to decrypt them or restore them. For that, we have a separate article with detailed instructions on what you have to do in order to unlock your data. Here is a link to that guide.

Any infection that belongs to the Ransomware family must be seen as a serious threat to your computer’s security and must be kept as far away from your system as possible. However, as you cannot know the exact sources of each and every piece of malware from this category or from another one, it is perfectly possible that you get your system infected even if you have been cautious and vigilant while online. And, if the malware program that has infected your computer is a Ransomware cryptovirus like Mtogas, then you really don’t have a lot of options. Here, however, we will do our best to give you useful advice on how to act in such a situation and we will tell you about the options you may have so that you can decide what to do next. The file-encrypting viruses like Mtogas, Krusop, Masok are definitely not something you’d like to land on your computer but with the right guidelines and with some luck, you may just be able to minimize the harm that such an infection may have caused.

Alternatives for encrypted .mtogas files

As you are probably aware, the purpose of a cryptovirus Ransomware infection is to extort money from its victims. The way such a virus is able to do that is through the use of the otherwise harmless process of file-encryption. Once the malware piece enters the computer, it “takes hostage” the personal files of the user by locking them with its advanced encryption. The files stay intact but can no longer be accessed through any regular means that the malware victim may have at their disposal. After the encryption, the only surefire way of opening any of the files is through the use of the unique key that corresponds to this particular encryption algorithm. It is exactly this key that the hackers behind Mtogas are readily offering you in exchange for a ransom payment. Depending on the specific Ransomware and who or what the victim is, the requested sum may vary greatly. In most cases, however, it will, at the very least, be a couple of hundred dollars. It is understandable if paying such a sum to get your files back isn’t perfect for you. Also, it’s important to mention that paying doesn’t actually mean that you will definitely get your files restored. For all you know, the hackers may simply be lying to you in order to get your money – they may not really have a working key or they may decide that they simply won’t send you anything after the money is received. The point is, you can never be really sure what to expect and that is why paying the ransom isn’t perfect. Ideally, if you have a backup of your files, all you’d need to do is use our removal guide for Mtogas to eliminate the Ransomware and then restore the files from the backup. If you don’t have a backup, you can use our second section of he guide where you can find some alternative file-recovery suggestions. Keep in mind, though, that those may not always work and we can’t give you any guarantees about the future of your data.
