The detection of JS/Adware.Chromex.Agent is an indication that a malicious program or file is trying to access a target internet browser application, especially Google Chrome. There are two ways in which JS/Adware.Chromex.Agent can execute its malicious tasks towards the internet program. One is to have itself installed as an extension that commits unwanted modifications to the homepage and search settings. On the other hand, this malware attempts to open the browser to a predefined website like an unwanted search engine.
If ESET antivirus or similar security programs identify the existence of JS/Adware.Chromex.Agent on the computer, complete virus scanning is highly recommended. This will not only remove the specific threat but also find and delete any types of files that are related to it.
About the syntax JS, Adware, and Chromex
The “JS” in this virus detection JS/Adware.Chromex.Agent refers to a JavaScript file. It means that it has identified a malicious JavasScript file that can perform harmful actions depending on how the attackers designed it. In this kind of infection, the attack may not be as hazardous as compared to virus contamination. The attackers are leaning more on a revenue-generating scheme that may yield from disturbing pop-up ads and redirects.
Adware is a term that refers to Ad-supported Software. Browser extensions, toolbar modules, and programs that were installed on the computer without the user’s consent are often called adware. Their objective is to issue advertisements, promote a product, or redirect the web users to partner websites. Though adware is not as hazardous as computer viruses, its redirect schemes can cause web users to visit sites that operate a drive-by-download scheme, which could result in virus infection.
With regards to Chromex, the detection objectively identifies threats that are under the Chromium open source application. One example is Google Chrome. In this attack, the malicious JavaScript file aims to access the Chrome browser and integrate itself as a browser extension or plug-in. There are also cases where the script aims to open the browser pages to a predefined web address for the purpose of misleading the web users with a page claiming that the computer is infected with viruses. It then suggests to follow the recommended solution that may end up causing web users to purchase a rogue tool.
How does JS/Adware.Chromex.Agent infect the computer?
There is no shortage on a scheme where attackers are distributing JS/Adware.Chromex.Agent. Hence, the one that stands out in the widespread campaign is via the malicious advertising scheme. Pop-up ads pretending to be software updates or alert pages were creatively designed by attackers to lure users into downloading the recommended program. Once executed on the computer, it drops or decompresses the content containing the JS/Adware.Chromex.Agent malware.
Software piracy is seen as another scheme that successfully spreads a copy of JS/Adware.Chromex.Agent. It was noted that the malware code is embedded in the free software and secretly loads into the computer during the setup process.
Symptoms
A pop-up warning from ESET or a similar antivirus program stating that a file is identified to be infected with JS/Adware.Chromex.Agent is one sign that the computer is under attack. If the security program fails to detect the threat, users may witness some symptoms like excessive pop-up advertisements and repetitive browser redirects. A browser or search hijacking occurring on the computer is also deemed another symptom of JS/Adware.Chromex.Agent infection.
