Nullbyte virus Removal Guide
What is Nullbyte ransomware virus?
Nullbyte and the dangers of this ransomware virus:
Nullbyte virus has recently hit the Internet, and the experts are still learning new things about it. There are several theories about the origin of this infection. Some researchers claim that Nullbyte is based on, or is a clone of Detox and Serpico ransomware which have been unleashed online not that long ago. Others debate on its potential connection to the new Cerber 3.0 version. While none of these theories have yet been confirmed, let us discuss the facts we already know about this fraudulent cyber infection. In this article we introduce this new cyber infection, discuss its basic working principles and recommend strategies that can help to avoid it. In the end, you will find Nullbyte removal suggestions and a detailed elimination guide. If you are desperate for a quick solution, you can initiate the system scan with an automatic antivirus software, such as FortectIntego.
Undoubtedly, Nullbyte virus belongs to the category of ransomware infections. It uses a complex algorithm to lock hundreds of file types, adding _nullbyte extension to indicate the already encrypted ones. Such files may look something like this: “randomfilename.jpg_nullbyte”. Once all the intended files are encrypted, it is time to explain the whole situation to the computer owner. To do that, the criminals employ a lock screen on which they display a ransom note. There is no way such a message is missed because it will pop up every time you boot your PC. The ransomware lock screen window is already integrated with the file decryption function and provides a BitCoin wallet information in case you decide to buy out files. Sadly, most of the victims succumb to the ransomers’ demands and pay up. This way, the criminals are simply getting rich and receive funding for the creation of even more malicious programs. Though the ransom Nullbyte demands is not as obscene as most of the ransomware viruses are famous for (only 0.1 Bitcoin), it ensures a higher success rate: the users are less hesitant to pay smaller amounts of money to redeem their data. If you are already reaching towards your back pocket – don’t hurry. You can get your files back absolutely free. The security experts have investigated the infection and found some vulnerabilities that allowed to create a working Nullbyte decrypter. The link to this tool is provided in the ransomware elimination guide below. Just do not forget to remove Nullbyte from your PC before you run the decrypter and double-check the system when you are done.
Can you fight against this ransomware infection?
Though ransomware viruses are said to be among the most dangerous and unpredictable cyber infections, they can be avoided if you know how the main principles of their distribution. Reports show that Nullbyte may infiltrate computer along with the PokemonGo cheating program called “Necrobot.Rebuilt”. More commonly, though, it uses the regular ransomware spreading techniques, such as spam emails, fake software updates or the fraudulent “claim-the-prize” ads. So, the best way to fight this infection is to avoid it. Even if Nullbyte malware is already on your computer, you should not interact with it directly and use antivirus tools as well as trusted decrypters to decontaminate it and redeem your files.
