Js/Adware.Agent.AW is an adware application that specializes in the aggressive generation of sponsored web ads. Js/Adware.Agent.AW attaches itself to popular web browsers to perform its ad-generating activity and, as a result, spams the web pages the users visit with unwanted pop-ups and banners.



If you perform a search in Google or Bing, you may have an alert from your Internet Security detecting a Js/Adware.Agent.AW. The alert popping out on Bing and Google searches and says that Chrome is trying to connect to a.xfreeservice.com (https:// a.xfreeservice.com/partner/8oB939m/index.php. Adware-based apps are not uncommon and while they are not as scary as viruses, like ransomware or Trojans, they still can be difficult to remove and can cause possible problems related to your computer’s protection and your web browsing experience. Js/Adware.Agent.AW, in particular, is new adware , very similar to Js/Adware.Agent.AA and Js/Adware.Revizer.E , that is tricky to uninstall and has the ability to gain control over the system’s main web browser (be it Chrome, Firefox, Edge, etc.) and have a rather undesirable effect on the way it behaves. Some of the most likely modifications that occur when adware like this one is attached to the browser are related to the installation of additional ad-generating components that ensure a constant stream of sponsored advertisements during the web browsing sessions. All of this is typically done without the user’s informed consent. In addition, some adware apps add new toolbars, buttons and different free tools to the browser that might seem to be there to enhance the browsing experience of the user, but they are not really useful in most cases and usually only facilitate the display of more ads on the screen.

The purpose of apps like Js/Adware.Agent.AW is very simple– they’re used as product and websites-promoting tools that flood the browsers they’re installed in with different types of web advertisements, click-bait links, pop-up notifications and banner offers that redirect users to specific pages. The primary aim of the adware is to collect user clicks and site visits, as those generate Pay-Per-Click and Pay-Per-View revenue.

Remuneration models like those that we’ve just mentioned above are very common and they help many different (mainly free) websites, services, and software to support their developers financially. In most instances, however, users hardly get compensated for the annoying ads with whatever free functions and content the platform, software, or service offers. In reality, they are typically exposed to hard-to-remove pop-ups, ads and banners that cover the content of the pages they visit and, once clicked on, they redirect them to other web locations.

As a matter of fact, a lot of people fear adware and its ads because they know that a lot of illegal, sketchy and low-quality pages are opting for the promotion services of adware applications to be advertised and pull in more traffic. Needless to say, Ransomware, Trojan horse viruses, spyware, and other kinds of malware threats are likely to fill some of these pages. That’s why landing on them is not a good idea and you should do your best to avoid clicking on anything that could potentially redirect you to such sites. That includes the messages that Js/Adware.Agent.AW displays, since you never know where they may reroute you to. However, since we know that avoiding the promotional messages of the adware can be really difficult, we strongly advise you to complete the steps in the removal guide below as they will allow you to uninstall the unwanted program and permanently stop it from spamming your screen.
