Js/Adware.Agent.AW Removal Guide

What is Js/Adware.Agent.AW?

Js/Adware.Agent.AW is a generic name of adware that settled down on Google Chrome and other web browsers

Js/Adware.Agent.AW generic detectionJs/Adware.Agent.AW is a generic threat detection name that signals an adware infection on the machine

Js/Adware.Agent.AW is a generic threat detection name[1], which is usually delivered by ESET security software. Usually, a pop-up warning shows up when a PC user is searching the web using Google or Bing search (less frequently in Yahoo or DuckDuckGo) on the Google Chrome web browser. Anyway, the idea behind this detection is the same – the device is infected with a Potentially Unwanted Program (PUP), namely adware.

Js/Adware.Agent.AW Chrome detection warns users about unauthorized attempts to connect to a.xfreeservice.com (https:// a.xfreeservice.com/partner/8oB939m/index.php) server. It means that the adware-typer application is regularly arranging web browsers redirects to potentially dangerous websites that may be involved in malware distribution, data harvesting, or phishing attacks[2]. Such and similar adware programs have to be quarantined without a delay to prevent virus infections or privacy violations.

Name Js/Adware.Agent.AW
Type It's a generic AV detection name, which points out to the adware or PUP on the system
Related security software The detection is usually delivered by ESET security software
Related server a.xfreeservice.com
Symptoms If this adware infiltrates the machine, it triggers an excessive amount of ads, popups, banners, in-text links, as well as web browsers redirects to suspicious websites. The web browser runs slower, software sometimes freezes
Danger The adware itself does not pose harm to the machine directly. However, AV engine flags it due to connection to suspicious servers, data tracking, and potentially harmful advertising
Removal You can remove Js/Adware.Agent.AW adware from the machine using the AV engine that reports its presence. However, you have to clean the web browser from PUPs manually (follow the guide given below)
Adware damage PUPs change some registry entries, install unwanted entries on the machine, and initiate other tasks that eventually cause web browser's malfunctioning and weaken system's security. Thus, to fix the damage, scan the machine with FortectIntego or similar security tool

Js/Adware.Agent.AW is a generic detection name that is typically delivered by ESET anti-virus software. In most of the cases, this detection is an alarm that the system contains an adware-program, which has hijacked the web browser (Google Chrome, Mozilla Firefox, Internet Explorer, etc.) and is initiating schematic advertising activities.

Usually, Js/Adware.Agent.AW ESET notification emerges when the user is trying to initiate regular web browsing activities. According to the reports[3], the problem prevails in Google and Bing search engines, while other search engines like Yahoo, DuckDuckGo, Baidu, Yandex, Ecosia, and others seem not to be affected.

The Js/Adware.Agent.AW virus detection is reported when browsing via Google Chrome in particular. That's because the problem is usually triggered by Chrome-based extensions, such as AdBlock, YoutubeAdBlock, YTD Video Downloader, Vimeo Video Downloader, and others. Such and similar ad-supported extensions are programmed to connect to the a.xfreeservice.com server, which seems to be malicious and is immediately blocked by the AV engine that has a real-time protection feature.

Aside from attempts to connect to unwanted servers, the Js/Adware.Agent.AW virus may try to push unwanted ads in various diverse forms, such as banners, pop-ups, full-page ads, and similar. Besides, it may be the reason why the web browser keeps redirecting to suspicious websites that contain false claims that you're a lucky visitor who is on the verge of winning some valuable prize.

The Js/Adware.Agent.AW redirects can expose users to potentially dangerous websites that contain rogue software downloads, promote fake software updates, or use stealthy cookies that harvest your IP address, geolocation, or even some pieces of Personally Identifiable Information (PII) without notifying users about that.

This particular detection name is used by ESET antivirus exclusively. However, if you are using another security tool, it may try to warn you about Js/Adware.Agent.AW virus using another generic name. The most common references to this infection are as follows:

  • Adware:JS/Agent.A!MTB
  • Js/Adware.Agent.AA
  • JS:Adware.Lnkr.A
  • JS:Adware.Agent.VTZ
  • Adware.Agent.Win32

Anyway, it's important not to ignore the Js/Adware.Agent.AW virus warnings because having an unwanted program on the machine can cause various inconveniences while web browsing or even serve as backdoor access to more malicious cyber infections.

However, sometimes people won't be able to remove Js/Adware.Agent.AW virus from the machine because it's not there. This detection, though rarely, can be a false-positive. It means that the security software that you are using contains a false virus database, which reports non-existent cyber threats. If you suspect this detection to be a false positive, you should disable the current AV software and download an alternative security program.

If it reports adware-related detection, you should initiate Js/Adware.Agent.AW removal without a delay. You can do that with the help of your AV tool. When it delivers an adware detection, set the software to remove PUPs from the machine. After that, clean your web browser and fix malware damage using FortectIntego tool.

If, however, Js/Adware.Agent.AW virus removal fails, you should manually check the list of installed applications and get rid of each suspicious/unknown entry from your machine. The problem is typically triggered by ad-block extensions, so delete PUPs from the programs' list and then eliminate suspicious extensions from Chrome and other web browsers. A full guide on how to do that is provided at the end of this article.

PUPs spread silently in disguise with freeware

There are various categories of cyber threats. Some of them are extremely malicious (trojans, spyware, ransomware, etc.) and their infiltration can hardly be foreseen. However, infiltration of a dangerous piece of software can be prevented by not visiting suspicious websites, downloading software from official websites, not using P2P services, avoid torrenting websites, regularly updating software, and having a professional AV security suite installed.

However, less dangerous applications, such as adware, browser hijackers, and PUPs are being distributed in a legitimate way, though stealthy enough to make people download them without realizing their presence. Ad-supported programs are typically distributed by bundling. This method is closely related to freeware, i.e. freeware providers pack their apps along with unwanted programs and spread them as a single unit.

Please note that unwanted apps are pre-selected, so accepting the installation of the main freeware installer grants access to the entire bundle. Luckily, it's possible to decompose the bundle. You should opt for the Advanced or Custom installation option and unmark checkmarks saying that you agree with the installation of extensions, add-ons, plug-ins, or whatnot.

Get rid of Js/Adware.Agent.AW related adware to stop advertising and connections to dangerous servers

Js/Adware.Agent.AW removal is not a difficult task to accomplish. This detection signals an adware-type program on the machine, which seeks to collect clicks, increase visitors' rate to affiliated websites, or downloads of third-party apps. Although it's non-malicious in its nature, the adware can be very intrusive or sometimes lead to virus infection. Luckily, their removal is not that difficult as it may seem.

For that, click on the pop-up warning brought by security software and select quarantine or remove option. After that, make sure to delete unwanted Chrome extensions or, at best, reset the web browser's settings to default.

How to prevent from getting adware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
