Nsemad virus Removal Guide

What is Nsemad ransomware?

Nsemad ransomware – a cryptovirus that locks all non-system files and appends .nsemad extension to them

Nsemad ransomwareNsemad ransomware - a virus that scares victims into paying the ransom.

Nsemad ransomware is a file-locking computer virus that encrypts all personal victim data (pics, documents, archives, etc.) on an infected device and then demands a ransom to unlock them. All locked files are appended with a .nsemad extension, thus making them inaccessible.

As soon as any ransomware, including .nsemad file virus, gains entry to a computer, it scans the most frequently used files (.doc, .xls, .pdf, or any other file type) then encrypts all of them. After that, the cryptovirus generates and displays text files, named HOW TO RESTORE YOUR FILES.TXT, with ransom information and demands.

In order to restore access to their files, victims of ransomware virus would have to reach out to the cybercriminals via two given emails – retrnyoufiles23@tutanota.com or John32Dillinger@seznam.cz and, most likely, pay a forward the ransom payment in cryptocurrency Bitcoins.

System fix Using the FortectIntego app might undo all the damage that the virus might have done to system settings and their files

The creators of Nsemad ransomware start their ransom note message by stating that all files on the victim's device have been encrypted and that only they have the ability to unlock it. Then they provide two emails which should be used to contact them.

Just like in other ransomware developers, such as Nobu, Igdm, Cerber 4.1.6, and others, Nsemad ransomware makers offer free decryption of three files (not exceeding 1Mb) from the infected machines, thus trying to prove that the necessary tool exists and that they would send it to the victims.

FBI states[1] that paying the ransom only encourages the cybercriminals to expand their attacks and fuels their research for more effective ways to distribute their creations. Furthermore, the ransom money could be used to create more sophisticated ransomware.

With that being said, victims should remove Nsemad ransomware immediately after detection or the first sight of ransom notes. Use professional anti-malware software like Malwarebytes or SpyHunter 5Combo Cleaner to perform a full system scan and eliminate the virus with all of its components.

Once Nsemad ransomware removal is completed, we recommend performing a system tune-up. Ransomware usually makes changes to system settings and system files (without encrypting them), and that could lead to abnormal behavior exhibits from your device. Take care of the overall system health with software like the FortectIntego.

The message in the HOW TO RESTORE YOUR FILES.TXT ransom note reads:

Contact us: retrnyoufiles23@tutanota.com or John32Dillinger@seznam.cz
Write us if you want to return your files – we can do it very quickly!

We always reply within 24 hours. If not – check spam folder, resend your letter or try send letter from another email service (like protonmail.com).
Do not rename or edit encrypted files: you may have permanent data loss.
Do not edit or delete any virtual machines file
To prove that we can recover your files, we am ready to decrypt any three files (less than 1Mb) for free (except databases, Excel and backups).

Although manual elimination is possible, we recommend leaving this dirty work to professional anti-malware software like Malwarebytes or Malwarebytes, which will automatically locate and delete the virus with all it's allocated files.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
