When we discuss malware-caused contaminations, most of them are blamed on Trojan horse viruses. In spite of that, the most horrible infections ever recorded have been caused by the members of another virus category – Ransomware. That’s why we have created the article below – to help you understand the features and effects of one particular Ransomware version: Nos Ransomware. We have also tried to advise you on how to counteract this awfully malicious infection in a wise and rather successful way. Generally speaking, Nos Ransomware is version of the so-called file-encrypting Ransomware, which is capable of sneaking into your PC without asking for your clear permission; and after that making you unable to access the files it has blocked. Later on, this malicious piece of software sends a message to inform you that the hackers behind this program expect you to pay a ransom in exchange for the decryption of the affected data.

What may be expected from a threat such as Nos Ransomware:

As typical file-encoding Ransomware, this particular malware version normally performs an extensive data-encoding process. Generally speaking, the encryption process takes place after the malware has already decided which data exactly you cherish most. In fact, not only does the virus determine the files that are to be encrypted, but it also compiles a very detailed list with all of them. Later on, you will receive the frightening alert message, which states that you owe some cyber criminals ransom and you have to pay it before a certain deadline. Just note that it’s possible that you may be able to notice this process of encrypting files as long as it’s still going on. Nonetheless, it happens very rarely, only in certain cases. However, if you see an unfamiliar process in your Task Manager, please, shut down your system, and go to an expert for help. It might be a Ransomware virus encoding some super important files.

Almost nothing can be done after the whole encryption process ends. To our and your disappointment, these file-encoding viruses are extremely difficult to counteract. Indeed, even some professionals in the field may find it very hard to get rid of the virus without paying the requested ransom, and recover the affected files as well. Furthermore, to be realistic, you have only a slight chance of success when dealing with Nos Ransomware and we do not want to lie to you about that. In spite of all that, it will be useful to try to remove the infection. Simply seek different options before you agree to pay the requested money to the cyber criminals, who are blackmailing you. Such an alternative could be contacting a professional in the field for advice and/or assistance. Maybe you could also purchase some special software to face and remove the contamination. Also, you may want to check out our special Removal Guide below. Perhaps the steps there will be what it takes to decrypt your files and remove the virus. Still, we cannot promise that.

Where could Ransomware be found?

Hackers may could spread these terrible viruses via many means:

  • Emails/ their attachments: Especially the ones from unfamiliar senders, may be aiding Ransomware. Furthermore, the attachments of such letters might be contagious. What we can advise you is to stay away from all emails from unknown sources that may look suspicious to you, and their attachments.
  • Leading to malware ads (the infamous Malvertising): Malvertising is another very likely source of Ransomware. In fact, your PC may automatically get infected with a malicious program provided that you click on the contagious ad, no matter whether you do it intentionally or unintentionally.
  • Fake update requests: One more likely source of Ransomware are the fake update requests you may receive, which are not generated by your OS, but acting in the same way as the aforementioned malicious ads. However, they may really resemble the original ones. To stay away from such dangers as Nos Ransomware, just update your PC manually and check for updates yourself whenever you can.

Some general advice:

  • Do not pay the requested ransom as soon as you get the notification. Search for a different possible solution. Your files are already in danger as it is; don’t risk your finances as well.
  • Make an attempt to just avoid all potential sources of this terrifying software. Try to stay away from them all and eventually, you will get used to a safe manner of browsing the web.
  • Spend your money on the best tool against malware. Do a little more research and look for the most efficient program – we promise that this is the core of good prevention practices and you will not regret it.
