Trojan horses are perhaps the most famous cyber threats. They represent the most common viruses you may come across on the Internet. Their characteristics and distribution sources might vary greatly. This is the reason why this article exists – to inform you about the possible effects which could result from an infection with a particular Trojan better known as JS/ExtenBro.Agent.DJ Virus.

What to bear in mind if you are experiencing a Trojan-caused infection:

The so-called Trojans are a category comprising lots of viruses with differing functions. What makes them a family is the way they infect, and later on – cause some damage to you or/and your system. Usually, all their actions may go completely unnoticed. Normally, the victim users realize some contamination has taken place after the virus program has already harmed their PCs in some way. Obviously, we DO recommend that you check your computer for malware as regularly as possible. New and unfamiliar viruses appear daily and your specific anti-malware program might not have included them all in their corresponding databases. Moreover, bear in mind that a functioning anti-virus app is a regularly updated one. Updating this program on a daily basis is strongly recommended.

Why these malware-based programs are called Trojans:

We have already discussed the normal way of acting of all the Trojans in the paragraph above. They infect your PC subtly, and after that they just lurk there in a silent way, while waiting for the right time to carry out all the malicious activities they may have been programmed to. The way they work has reminded programmers of the way the wooden horse from the infamous Trojan War in fact won the war. We all know that the people in Troy thought it was not dangerous at first. Later on, the Greeks inside it got out and conquered the city.

What could possibly go wrong because of an infection caused by JS/ExtenBro.Agent.DJ Virus?

Probably the most horrifying aspect of getting contaminated by any Trojan version is the uncertainty. You will never be able to tell what the actual goal of JS/ExtenBro.Agent.DJ Virus is, before this malicious software has managed to achieve its indecent purposes. Down in the article we have tried to enlist the typical usages of JS/ExtenBro.Agent.DJ Virus and Trojans generally. However, do keep in mind that this list cannot include all the possible ways of acting, only the most common ones.

  • Hackers may simply be enjoying themselves: Indeed, this may be the truth. Several hackers could be willing to develop and distribute malware as a way of having fun and checking how fat their own skills and creativity can go. This is neither acceptable, nor is it harmless. However, you can never know what exactly those cyber criminals have done to your system.
  • Just for destruction: Simply as it sounds, many criminals could just desire to crash some devices and destroy some files. No information or money gets demanded from you. The hackers who have created JS/ExtenBro.Agent.DJ Virus may simply delete the content of your drives; modify some data; or completely harm your device.
  • Stealing important info and details (sometimes even the whole identity is in danger): This particular possibility is among the most terrifying ones. Such malicious programs, JS/ExtenBro.Agent.DJ Virus included, could get exploited, and usually do, for accessing some sensitive details. Many cyber criminals need access to someone’s social media accounts or banking credentials for the purpose of doing something illegal. Depriving you of your money or getting you in another possible disaster is more than just likely. Such a case may involve the victim users ending up incapable of proving that they are themselves. All of their private details, which are available on the web, could get altered or destroyed.
  • Spreading other hazardous malware versions: Typically, Trojan horse viruses get exploited for distributing other malware versions, mostly Ransomware-based ones. The rest is history, as people say – Ransomware is the threat you don’t want to face, which may result in the loss of your most important data.

Online sources which are likely to contain viruses like JS/ExtenBro.Agent.DJ Virus:

Once more, there are many various options. We are not able to cover all of them in just one text. Still, we can definitely mention the most common of them:

  • Fake advertisements (including pop-ups and banners);
  • Torrents, videos, shareware and illegally distributed software, as well as all the websites which include them;
  • Some emails, as well as some of their attachments.

    Sidenote: Readers of this guide are advised to bookmark this page or have it opened on another device since it is possible that they will need to close the browser at a some point during the tie they are completing the following steps.

    Step 1

    The first thing that needs to be done prior to anything else is that you boot your PC into Safe Mode. If you are not sure how to do it, use this link to a guide on how to enter Safe Mode.

    Step 2

    Press Ctrl + Shift + Esc to open the Task Manager. Go to the Processes section and look for any suspicious-looking processes. Usually, malware processes use high amounts of RAM and CPU and also have shady description (or none at all). Right-click on those processes and select Open File Location. If you are sure that the process is coming from the virus, delete everything in the file location. Also, right-click on the process again and then select End Process.

    Step 3

    Press Winkey + R and type appwiz.cpl. Press Enter and in the newly opened window look for any shady program installs. Right-click on the suspicious programs and select uninstall. Follow the prompts to uninstall the sketchy application.

    Step 4

    Open the Run window again (Winkey + R), type msconfig and hit Enter. Go to the Startup section and from the list of programs, uncheck everything that seems shady or has an unknown or suspicious-looking manufacturer. Click on OK. On Windows 10, the startup programs list is in the Task Manager.

    Step 5

    Open the Start Menu and paste the following line in the search bar: notepad %windir%/system32/Drivers/etc/hosts. Click on the first result that gets displayed. A notepad file should open, look at the bottom of the text and see if there are any IP addresses below localhost. Write to us in the comments if you saw anything there.

    Step 6

    Type regedit in the Run search bar and hit Enter. When the Registry Editor opens, press Ctrl + F, type the name of the virus and select Find Next. If anything gets found, right-click on it and select Delete. Do this for all search results.

    Additionally, manually navigate to the following directories and see if they have any folders/keys that look shady (with a lot of random numbers and letters):

    • HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Run
    • HKEY_CURRENT_USER > Software > Microsoft > Internet Explorer > Main
    • HKEY_CURRENT_USER > Software > Any other random directory

    Delete everything that looks suspicious. If you are not sure whether to delete something, be sure to ask us in the comments.
