JS/Adware.Subprop.E – a detection name for a potentially unwanted program on a Windows machine

JS/Adware.Subprop.EJS/Adware.Subprop.E is a computer virus that is categorized as adware

JS/Adware.Subprop.E is a heuristic[1] detection name given an adware app that might have accessed your PC without permission. Adware belongs to a category of potentially unwanted programs that use deceptive distribution techniques and install components that would display popups, fleshing windows, in-text links, banners, and other types of ads on Google Chrome, Mozilla Firefox, MS Edge, or another web browser.

Since JS/Adware.Subprop.E virus name is generic, it means that many differently-named apps can be detected as such. Antivirus programs provide such names to unwanted apps based on their behavior rather than other factors, such as the signature of the installer. A “JS” part stands for JavaScript,[2] which means that malicious JS files could be populated on various sites and would otherwise attempt to load an ad or, in some cases, download files to your computer automatically.

Name JS/Adware.Subprop.E 
Type Adware, potentially unwanted program
Distribution Software bundles, third-party websites, deceptive ads, fake Flash Player updates
Symptoms Symptoms are not universal. If adware managed to get into your device, you might see changed browser settings, increased number of ads, slow browser loading times, etc.
Dangers Adware can significantly decrease the performance of the internet and browser speed, redirect to potentially malicious websites, prevent finding relevant information due to ads, result in additional PUP infections and monetary losses
Elimination To get rid of unwanted apps manually, you can follow our removal guide below. If the unwanted ads and other disruptive behavior does not stop, you should scan your computer with security software and delete all threats automatically
Further steps Malware or adware infections can diminish the performance of your computer or cause serious stability issues. Use ReimageIntego to remediate your device and ensure that the virus damage is fixed

Although adware is not considered to be as dangerous as, for example, a Trojan or ransomware, it is still a security threat, so you should immediately proceed with JS/Adware.Subprop.E removal if your security software has flagged it. If you cannot quarantine the malicious file with your currently-installed anti-malware, we suggest you try SpyHunter 5Combo Cleaner or Malwarebytes.

Adware's operation on the computer may vary, as there are hundreds of thousands of different programs available, and new ones are developed every day. Some might merely change your web browser settings and append a customized search engine, while others might establish persistence by modifying the Windows registry or other Windows components. In some cases, security software is not capable of fixing Windows system files, so we recommend using ReimageIntego to avoid operational problems after a malware infection.

There are several ways of how JS/Adware.Subprop.E adware could spread around the internet. Experts claim that the following methods are used most frequently:

  • software bundles;
  • deceptive ads;
  • fake updates.

In general, there are various scenarios when you could encounter a warning from your security software. If you attempted to download an app from an unsolicited source, you could have received a pop-up from your anti-virus, claiming that JS/Adware.Subprop.E is attempting to penetrate your system.

In other cases, the warning could show up after you got redirected to a malicious website. This could also mean two things: either you clicked on a suspicious link/visited a malicious site, or you already have adware installed on your machine (which is causing these redirects).

JS/Adware.Subprop.E virusJS/Adware.Subprop.E is a heuristic detection name given potential threats by various security vendors

The problem with generic detections is that they suffer from a high number of false-positives and JS/Adware.Subprop.E is not an exception. Quite often, users say that they were attempting to download a fully legitimate application from the developer's official website, and they received a warning from their security tool. Mistakes happen because security apps mistakenly detect some patterns that might be considered suspicious, hence the false-positives.

Therefore, you should not immediately remove JS/Adware.Subprop.E if you believe that the file you were downloading is safe. Instead, update your anti-malware, or scan it with an alternative engine. Do not forget that each of the detections should not be ignored and investigated fully.

If it turned out that JS/Adware.Subprop.E virus is not a false positive, get rid of it immediately by sending it to quarantine and then removing it from the system immediately.

Adware can be spread in many different ways

Adware is a part of the potentially unwanted program category, and it is called so for a reason. Previously called spyware, adware managed to get itself a name within the software development and distribution business. Since, due to legal reasons, such programs cannot be called “malware,” security vendors use this name in order to warn its users about some potentially dangerous or unwanted features that the app can bring after the installation. This is why keeping up-to-date security software on the computer is so important.

All in all, you should avoid adware like a plague, as its functionality is very limited, if not useless. In the meantime, you would get ads, ads everywhere! In the background, such apps are there to spy on your online, so you are risking your privacy as well. Thus, prevent the unintentional installation of adware with the help of these tips from novirus.uk[3] security experts:

  • Try to avoid third-party websites when downloading new software;
  • Never download pirated programs or software cracks – these might result in the installation of malware, such as Agho ransomware;
  • During the installation, always opt for Advanced/Custom settings instead of Recommended/Quick ones;
  • Remove the ticks from pre-ticked checkboxes;
  • Read the fine print;
  • Watch out for misplaced buttons and deceptive offers.

Remove JS/Adware.Subprop.E if it is not a false positive

JS/Adware.Subprop.E removal can sometimes be perfumed manually – especially if you know which program is responsible for unwanted behavior. If you are unaware of how to uninstall programs from your computer, please follow the instructions we provide below. Also, after you get rid of adware, it is advised you also clean your web browsers by deleting cookies and other web data. You can also reset Chrome or other affected browsers if necessary.

If you received a popup from your security software seemingly out of nowhere, you should remove JS/Adware.Subprop.E virus immediately, as it might mean that a malicious script is trying to break in. Alternatively, if you are unable to delete the infection with your current anti-malware software, we suggest you rely on alternatives.

Finally, if you suspect that JS/Adware.Subprop.E is a false positive, you should update definitions of your security software and the app in question (if it is already installed). If nothing works, add the app as exclusion or contact the security vendor to fix the issue for you.

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
