Nosu is a piece of malware that seeks to lock your files via encryption. The goal of Nosu is to make you pay a ransom for the decryption of the locked data.
It sure is frustrating and unnerving to see that your files have been locked by a virus of the Ransomware category. However, panicking and losing your cool wouldn’t get you anywhere, and would, for that matter, probably make things even worse. This is why you must stay calm and assess your options before you do anything unwise.
The Nosu virus
The Nosu virus is a harmful piece of computer software known as Ransomware. The Nosu virus is used as a money-extortion tool – it seals its victim’s files and demands a payment to make them accessible.
Our job in this article is to help you make the best decision with regard to what to do about the Ransomware cryptovirus infection that you are currently faced with. We assume that the insidious Nosu virus has already placed its encryption on your files, and is currently demanding a ransom from you in exchange for their release. There are several things about this ransom we need to point out here. First of all, the sum required is oftentimes quite high – we are talking about four-digit sums. This is not a small amount of money and oftentimes people can’t afford to make such a payment, especially considering the short deadlines given by the blackmailers. However, even if you do have the ability to pay at a moment’s notice, the question is if you should do it. Usually, the answer to that is a soft no, meaning that it is inadvisable to go for the payment, but if you absolutely must try everything to get your data back, and if you are ready to lose a couple of thousand dollars, then you might as well pay. The reason we say this is simply – you might not get your data restored even after you pay for its release. After all, the people that are blackmailing you are criminals – this ransom payment isn’t a purchasing deal, it is a blackmailing scheme, and it’s not unusual for the hackers to refuse to release their victim’s files even after the payment gets made.
The Nosu file extension
The Nosu file extension is an extension that is placed on your files to keep them locked. The Nosu file extension is unrecognizable to all regular programs.
Now that we have made it clear that paying isn’t really your best option, we must talk about the alternatives. The first important thing to note here is that it’s absolutely essential to get rid of the cryptovirus that’s residing in your computer. You can use the guide from below and/or the professional anti-malware program in it to make sure the virus gets removed.
After the infection is dealt with, you will need to find a way to get around the data encryption placed on your files. The best way to do that is to simply restore your files from backups, but many users don’t have that. Nevertheless, you should still check all of your other devices, cloud accounts, and other online accounts for any accidental file backups.
Another option is to try the suggestions that are in the guide we already told you about. They are in its second section, and we encourage you to give them a try. Sadly, we cannot promise you that they will be effective – their effectiveness is likely to vary from one instance to the other. Still, the potential alternative recovery methods we offer you are free, and it won’t harm you to try them out even if they turn out to be ineffective in your case.
