Becoming a victim of a Ransomware infection could be a very unpleasant and extremely shocking experience. Nowadays, different businesses, institutions and, a big number of regular web users are becoming a target of this type of malware. .Noos is one of the latest representatives of the Ransomware category, and more precisely, the cryptovirus sub-category.

Once this infection nests itself inside the machine, it secretly blocks the access to the data stored there, and demands a ransom to be paid if the victims want to regain their access. Typically,  the malware encrypts files that are considered of great value, such as documents, archives, databases, videos, audios, images, and other types of potentially valuable data, with the idea that the victims will be more willing to pay a ransom to regain their access to the files, rather than lose them. The cyber-terrorists who control the infection demand a ransom in BitCoins or in another cryptocurrency in order to provide the victims with a key that can restore the files to their previous state.

The .Noos Virus

.Noos is a Ransomware used by its creators to blackmail their victims. .Noos targets the user’s files, locking them with a strong encryption, and demands a ransom for the decryption key.

If you have been greeted by a scary ransom-demanding notification somewhere on your screen, you are likely feeling intimidated, and desperate to find a powerful method or a roundabout way, that can help you avoid the ransom payment. Fortunately, on this page, you will find some alternatives which don’t involve giving your money to some anonymous crooks. Our “How to remove” team has prepared a Removal Guide with instructions which are designed to help you remove .Noos from your computer, and possibly get some of your encrypted files back.

Threats such as .Noos can cause harm in a very unusual way. Unlike harmful infections like Trojans or Spyware, which typically cause system damage or secretly spy on you, this malware doesn’t harm anything inside the system. It utilizes a rather harmless process – the file encryption – as its main weapon. Most antivirus programs do not recognize the file encryption process as a threat to your computer because this is a process that is used on a day-to-day basis to protect different types of information from unauthorized access.

The .Noos File Encryption

.Noos is a Ransomware threat that is intended to lock its victims’ files. A process called encryption allows .Noos to complete its task.

The file encryption is one of the most reliable data-protection methods available to this date. Its implementation is huge in sectors like banking, online payments, insurance, health care and more. People with malicious intentions, however, have turned this useful method into a method for online money extortion. By secretly encrypting your personal files and keeping the key for their decryption in secret, they are able to blackmail you to “purchase” the access key from them. This blackmailing scheme seems to generate a lot of money for the crooks since a lot of victims tend to panic and simply send the ransom with the hopes of regaining the access to their valuable information.

Sending money to the hacker, however, only stimulates them to keep developing Ransomware viruses and infecting more unsuspecting online users with them. Besides, there are no guarantees about the future of the encrypted files, even if you strictly follow all the ransom demands. This is the reason why we often advise the people who land on our “How to remove” site to explore other alternative options of coping with the Ransomware, instead of paying the ransom. If you don’t know where to start, our removal guide below is a good starting point. It will certainly assist you in getting rid of .Noos, and might also give you some ideas on how to recover your encrypted files from.
