Nemesis Virus

The main subject of the article that you are reading now is a new Ransomware version called Nemesis Ransomware. This Nemesis virus has some very malicious abilities – it can easily encrypt all of the files, found on the infected computer, and then blackmail you to pay ransom to decrypt them.

What is even worse about this Ransomware is that the consequences for your system, and especially for your data, can be very malicious and sometimes even irreversible. However, there are a few possible actions that can help you combat the infection and in the next lines, our team will provide you with some useful information on that. Also, at the end of the page, you will find a specially assembled removal guide. It may help you remove Nemesis Ransomware and eventually minimize its dreadful consequences, so take advantage of it to avoid the ransom payment.

Nemesis Ransomware – a tricky instrument for online blackmail.

Ransomware threats like Nemesis Ransomware are developed with only one main purpose – to bring profits to their criminal creators through a very nasty blackmail scheme. These malicious pieces of software use a very strong file encryption algorithm to lock each and every file found on the compromised computer. This way, they prevent the owner from accessing their own data. Once the encryption is completed, the hackers, behind the Ransomware, start to ruthlessly threaten and blackmail the victim to pay ransom if they want to ever access their data again. From different businesses and institutions to normal online users, no one is immune against such a harassing infection and unfortunately, there is very little that could be done once the threat gets inside the machine. That’s why Ransomware has gained its fame as one of the most invasive and dangerous malware types one could encounter.

How can such a threat infect you?

The latest and more advanced versions of Ransomware like Nemesis Ransomware are incredibly flexible in their methods of distribution and infection. The hackers usually spread such nasty threats with the help of compromised web content, torrents, drive-by downloads, infected files, installers or web pages. Spam and fake emails with malicious attachments are also effectively used to infect the users with Ransomware. However, in most of the cases, Nemesis Ransomware finds its way inside the computer with the help of a Trojan horse. That’s why, when it comes to detecting and removing the infection, one should always double check its system for a Ransomware-Trojan combo in order to successfully eliminate all of the traces from the machine.

Is it possible to detect Nemesis Ransomware before it has encrypted your files?

Unfortunately, in most of the Ransomware cases, there are hardly any signs that can indicate that a malicious encryption is locking the files on the computer. The process goes silently and usually remains under the radar of most antivirus and antimalware software. This is another reason that makes this type of infection really tricky and sophisticated. The victims normally come to know about Nemesis Ransomware only after all of their data has been encrypted. A ransom note reveals the malware and places the hackers’ ransom demands. Oftentimes, a short deadline is given to the victims to pay, else they are threatened not to access their files again. The criminals usually promise to send a decryption key once a payment has been made, however, in most of the cases they simply disappear with the money.

Can you get your files back without a decryption key?

Only the right and matching decryption key can unlock the files, encrypted by Nemesis Ransomware. Without it, you cannot use or open them, no matter what you do. Still, not all hope is lost. Paying the ransom is surely not a smart solution, but there is something smarter you could do. You can remove the Ransomware from your system. The removal guide below can show you exactly how to do that. Unfortunately, we need to warn you that the effect of the encryption won’t go away and your files will still remain inaccessible even when Nemesis Ransomware is no longer present on your machine. However, once you clean your computer, you will be able to try to restore some of your data by other means. The best would be if you have some copies of your most important files somewhere on an external drive or a cloud. This way, you can easily restore them from there and send the hackers on their way, because they won’t get a penny from you. But what if you don’t have backups? Then you can try the file restoration instructions, which we have listed below. They may not be able to recover all of your files, but may still help you minimize the data loss to some extent.
