TrojanDownloader:JS/Nemucod

TrojanDownloader:JS/Nemucod detection states a serious threat to your privacy and security. Nemucod trojan is capable of injecting various other malware, including ransomware and stealers.

TrojanDownloader:JS/Nemucod is a type of malware that primarily targets Windows systems. It is known as a Trojan downloader because its main function is to download and install additional malicious payloads onto the infected system. Here are some key characteristics and details about TrojanDownloader:JS/Nemucod:

👉 Nemucod is JavaScript-based. It is primarily distributed through malicious JavaScript code embedded in websites or delivered through email attachments. When a user visits an infected website or opens a malicious email attachment, the JavaScript code is executed, leading to the download and execution of additional malware.

👉 Nemucod Payload Delivery. One of its main purposes is to download and execute other types of malware onto the infected system. This secondary malware could be anything from ransomware to banking trojans, depending on the goals of the attackers.

👉 Nemucod has a Polymorphic Nature. It has been known to use polymorphic techniques, which means it can change its code and appearance to evade detection by antivirus and security software. This makes it challenging for traditional signature-based detection methods to identify and block it

Any type of malware exists with the only target – make money on you. And the programmers of these things are not thinking of ethicality – they utilize all possible ways. Taking your data, getting the commission for the promotions you watch for them, exploiting your system components to mine cryptocurrencies – that is not the complete list of what they do.

It is better to prevent, than repair and repent!

What does the notification with TrojanDownloader:JS/Nemucod detection mean?

The TrojanDownloader: JS/Nemucod detection you can see in the lower right side is shown to you by Microsoft Defender. That anti-malware application is pretty good at scanning, but prone to be unreliable. It is unprotected from malware invasions, and it has a glitchy interface and bugged malware-clearing features. For this reason, the pop-up that says concerning the Nemucod is just an alert that Defender has identified. To remove it, you will likely need to make use of a separate anti-malware program.

Microsoft Defender: “TrojanDownloader:JS/Nemucod”

The exact TrojanDownloader:JS/Nemucod virus is an undesirable thing. It digs inside of your computer under the guise of something legit, or as a part of the application you have got on a forum. Then, it makes everything to make your system weaker. At the end of this “party”, it injects other viruses – ones that are wanted by cyber burglars who manage this malware. Hence, it is likely impossible to predict the effects of Nemucod actions. And the unpredictability is one of the saddest things when we are talking about malware. That’s why it is rather not to choose at all, and don’t give it even a single chance to complete its task.

Is TrojanDownloader:JS/Nemucod dangerous?

As I have specified previously, non-harmful malware does not exist. And TrojanDownloader:JS/Nemucod is not an exclusion. This virus alters the system configurations, and edits the Group Policies and Windows registry. All of these components are critical for correct system operating, even when we are not talking about PC security. Therefore, the virus that Nemucod carries, or which it will inject after some time, will try to get maximum profit from you. Cybercriminals can grab your personal information, and then push it on the Darknet. Using adware and browser hijacker functions, embedded in TrojanDownloader:JS/Nemucod malware, they can make a profit by showing you the ads. Each view gives them a penny, but 100 views per day = $1. 1000 victims who watch 100 banners per day – $1000. Easy math, but sad conclusions. It is a bad choice to be a donkey for crooks.

How did I get this virus?

It is hard to line the sources of malware on your computer. Nowadays, things are mixed up, and spreading methods chosen by adware 5 years ago can be used by spyware nowadays. But if we abstract from the exact distribution way and think about why it works, the reply will be quite simple – low level of cybersecurity knowledge. People press on ads on weird websites, click the pop-ups they receive in their browsers, and call the “Microsoft tech support” believing that the strange banner that says about malware is true. It is necessary to know what is legit – to stay away from misunderstandings when trying to figure out a virus.

The example of Microsoft Tech support scam banner

Nowadays, there are two of the most widespread tactics of malware distribution – lure e-mails and injection into a hacked program. While the first one is not so easy to evade – you should know a lot to recognize a counterfeit – the second one is simple to address: just don’t utilize hacked apps. Torrent trackers and various other sources of “totally free” applications (which are paid, but with a disabled license checking) are a giveaway point of malware. And TrojanDownloader:JS/Nemucod is just within them.

How to remove the TrojanDownloader:JS/Nemucod from my PC?
