What is a Trojan horse?

Trojan horses can be devastating if they manage to infect your computer system. The extreme versatility of viruses that belong to this malware category allows them to carry out all sorts of illegal and malicious tasks once they are inside the targeted PC. As of late, a new Trojan horse version has been released which is currently known under the name of Js_obfus.ymnjp Virus. Today, in this current article, we will try to ensure that our readers are well-informed about the most important characteristics of this piece of noxious software. If any of you have come to this page seeking help for removing the virus program from your PC, we could help you do that by providing you with a guide manual that we have added to this article. The instructions from the guide can aid you in eliminating the threat and making sure that it doesn’t return. However, you must first read the remainder of the article itself as a way to obtain a better understanding of what Trojan horses actually are and what they are really capable of.

Shady agenda

Above, we already mentioned that this particular malware type is highly versatile and most harmful programs that belong to it can execute all sorts of malicious and dangerous tasks. In the current paragraph, we will mention some of the things that a typical Trojan horse virus might be capable of. Just remember that this is by no means an exhaustive list of the potential capabilities of viruses like Js_obfus.ymnjp Virus and only a brief summary of the most frequently encountered uses of Trojans.

  • A lot of Trojan horses can be used to directly inflict damage to the victim’s computer system, which could oftentimes render the PC utterly unusable. The virus could corrupt key system files, cause critical errors and trigger Blue Screen (BSOD) crashes. The amount of inflicted damage may vary but in many cases, if the virus isn’t taken care of in time, the end result might be that the machine couldn’t be used any longer.
  • Another thing that some Trojans can do is spy on and stalk their victims. This can be particularly dangerous since through a number of different espionage methods, the hacker who is controlling the noxious program can obtain all sorts of information about the user. In some cases, the virus might even take control over the webcam of the PC and use it to directly stalk on the person who is currently using the computer without the latter having any idea about what’s actually happening.
  • Thirdly, a virus like Js_obfus.ymnjp Virus can also be used to stealthily provide some other malicious program with a backdoor into the PC’s system. Currently, such practices are very commonly employed for infecting systems with Ransomware.
  • The next thing that we must mention is that it is possible that a Trojan horse virus may start using your computer’s resources for different illegal tasks that would in some way benefit the cyber-criminal who is terrorizing you. Two very common examples are when the virus forces your PC to send out spam online messages or employs your computer’s resources for mining bitcoins that are later sent directly to the hacker.

Detecting Trojan horse viruses

Something that you must understand is that if Js_obfus.ymnjp Virus attacks your system, there’s a high chance that you wouldn’t notice anything. Symptoms during Trojan horse infections are scarce and while sometimes you might get lucky and notice that something isn’t the way it should be, in other instances there might be pretty much nothing to suggest that your machine has fallen prey to such a virus. Some potential symptoms that you might encounter if a Trojan gets inside your PC are unusually high use of system resources (RAM, CPU), frequent errors and freezes and also sudden Blue Screen of Death crashes. However, as we said, those are situational and it is possible that they could be caused by other issues unrelated to Trojan horse infections.

Taking the necessary measures

To protect one’s computer against Trojans, one needs to have a good understanding of how these viruses normally get distributed, as well as what precautions must be taken so as to prevent them from getting inside the PC system. Probably the most important thing here is to remember to be careful each time you go online since this is where the majority of malicious programs tend to come from. Avoid websites that might be potentially dangerous and illegal and only open e-mails and interact with links and file attachments from social network/Skype messages if you are certain that they are safe and not some sort of sneaky spam. Also, it is a good idea to get a high-quality security tool to help you detect and fend off potential Trojans and make sure to keep that program constantly enabled a frequently updated. Last but not least, do not forget to always install the latest updates to your OS and always keep the firewall enabled unless it is absolutely necessary to temporarily turn it off.

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.
