This page aims to help you remove Nasoh for free. Our instructions also cover how any Nasoh file can be recovered.

The category of Ransomware cryptoviruses is a highly dangerous and problematic family of malware threats. Here, we will go over the main characteristics of this group of viruses, and we will tell you what your options are if one new Ransomware threats named Nasoh has manage to enter your computer and lock your files with its advanced encryption algorithm. One thing you should remember while trying to deal with this insidious virus is that a full recovery of your data may not be possible at the moment. This due to the advanced encryption codes that threats like Nasoh use – breaking it or getting the decryption key may not always be an option, and the alternatives that you may use to bring back your files may also not be effective in all situations. Still, you should definitely take action towards handling this infection in the best way possible, or else, the consequences could be quite unpleasant and severe.

The .Nasoh virus

The .Nasoh Virus is the newest of the ever-changing ‘STOP Ransomware’ strain which has been plaguing users around the globe in 2019. The .Nasoh Virus primarily targets asian and african countries, through which it slowly spreads to the western globe.

Like most other Ransomware threats, Nasoh doesn’t really give away its presence in the system with any visible symptoms while it is busy encrypting your files. The most you may notices is a slow-down of your system and decreased free hard-drive space while the encryption process is still in progress. Those symptoms, however, aren’t all that apparent, and may also be caused by many other things, so noticing a Ransomware doesn’t normally happen.

 Another problem related to detecting Ransomware is that most antivirus programs lack the specialized features to spot this particular type of threats. Some advanced and high tier antivirus solutions offer detection features specialized for Ransomware but even those can’t guarantee that some sneaky threats like Nasoh, CoharosMasok won’t manage to silently enter your machine and lock up your data. Because of this, and because of the lack of easily-noticeable symptoms, most infections of the Ransomware cryptovirus category manage to lock the files of their victims. Once the encryption is over, the virus itself makes sure to make its presence known by showing a banner on the user’s screen, in which the user is told about the money that is required of them if they want their files back.

The .Nasoh file lockdown

The .Nasoh file are basically and extension that signifies your files were encrypted. As in the picture below, a .Nasoh file appears only when it is too late to save the file. The ransomware works in the background and adds the extension to each file as it progresses.

Obviously, if the locked files aren’t that important, the problem isn’t all that big. In fact, removing the virus is totally manageable, and you can do it yourself as long as you follow the instructions from the guide below and use the recommended removal tool. However, even if the malware gets eliminated, this doesn’t mean yoru files would get automatically released, and if those files are important to you, and you have no backups of them, then you may be in trouble. Unfortunately, though there are methods you can try in order to restore your data, and some of those methods will be presented to you in the second section of our guide, we can’t promise that they will work for all of you. Still, trying them out won’t cause harm and it won’t cost you anything, which is why we encourage you to at least give them a try.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections.


Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Type msconfig in the search field and hit enter. A window will pop-up:


Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.

  • Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.
