Every web user knows that the Internet is filled with all forms of dangerous software hazards. In this post, we will focus on one really dangerous and difficult to handle type of computer viruses which researchers tend to call Ransomware. This type of viruses is especially dangerous and challenging to handle since they differ greatly from all other forms of malware. You most probably have come to this page because you’ve been searching for information about Nemty – a recently launched Ransomware that belongs to the cryptovirus subcategory. What Nemty does is it locks the user’s files with a very complex and highly-advanced file encryption code. If the victims want to unlock them and regain their access, they would need to pay a fixed amount of money as a ransom in exchange for a special decryption key. All the details about the ransom transaction would usually be described in a ransom pop-up note that, in most cases, would get displayed on the infected Computer’s screen immediately after the file-encryption process completes. Giving your money to the hackers behind an infection like Nemty is neither the best nor the most advisable course of action. That’s why, down below, you can find an instruction manual which is focused on helping our visitors deal with the Ransomware virus in an alternative way which does not involve paying ransom to anyone. Feel free to use it in case the nasty Nemty cryptovirus has already infected your system and let us know the outcome in the comments section after the article.

What to do with .Nemty files?

Those of you, who want to effectively counteract Ransomware threats (Masodas, Versato) need to be familiar with their main traits and specifics in order to increase their chance for successful removal and recovery. Keep in mind, though, that this sort of malicious software is unique in the way it functions and this is the main reason why nobody can give any guarantees about the recovery from its attack.  The thing that you can expect from illegal software like Nemty is that it would initiate a system scan on all your hard drives. The malware is generally looking for a number of specific file types which later would be encrypted rather than harming your Computer in a specific way or corrupting its software. This itself is very different than what some other types of malware would normally do. The data types that the Ransomware will likely look for are photos, documents and also videos/sounds, personal files, etc. Once the scan is completed, each one of the targeted files gets copied by the Ransomware. When the file copy is created, the initial file would get deleted by the malware. The special thing about the copies made by the illegal software is that they are all secured by an advanced encryption code. With the help of this encryption code, the criminal that is controlling the malware is able to block their victim access to the targeted private files and later require a ransom transaction in order to send the user the decryption key needed for the sealed data.

The most serious problem that comes from the use of the data encryption is the fact this process is not seen as dangerous by a number of commonly used system security applications. This allows threats like Nemty to encrypt files without being detected and helps the criminals to blackmail the web users once they are denied access to their information.
