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 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 – firstname.lastname@example.org or John32Dillinger@seznam.cz and, most likely, pay a forward the ransom payment in cryptocurrency Bitcoins.

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 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.

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.
