What is Nuis Virus
Nuis Ransomware is a harmful file encryption virus which is been reported by researchers to use a strong AES-256 encryption key algorithm to encrypt the files of an infected computer system. Like the other ransomware, .Nuis Virus also overtakes your confidential data and asks to pay a ransom from the victim. It generally takes the advantage of Windows’ default behavior of hiding the extension from file names to disguise the real extension of the malicious file hidden in it.
Once installed, .Nuis File Virus will completely take over your machine.

It will demand ransom money to give you the decryption key that may decipher your data and you will be able to access your files. This .Nuis Virus Ransomware is a dangerous PC infection that leaves no choice to the user other than paying extortion fees but it is only aimed to cheat innocent users and thug their money, it will not decrypt your files as it promises.
Ransomware spread in various ways
.Nuis File Virus mostly intrudes on your computer bundled with free third-party programs that users download from shady websites. Those free applications may carry hidden attachments that can secretly get installed without asking permission. Spam email campaigns are another very often used method of malware spreading. Hackers hide malicious codes in attachments and send them to a large number of potential victims through automated software. When someone opens such an email and downloads attachments, threats like Nuis virus can easily get installed.
Unwanted pop-up ads and forced browser redirects are not only annoying but they can be used for malware distribution too.

Browsing torrent websites and downloading pirated software could also bring nasty viruses to your computer.
