A relatively new adware threat targeting computers on a large scale is being thoroughly dissected in this tutorial. It’s called Astromenda after the denomination of the respective web browser extension which gets dropped on a system. Aside from the means applied for the spreading of this pest, the article also covers a workaround to remove it from an infected PC efficiently.
The absence of user consent for setup and further modifications on a computer system, as well as out-of-the-ordinary intrusiveness are the intrinsic things that make programs like Astromenda malicious. In fact, antivirus tools are flagging this particular object as adware, Trojan or PUP (potentially unwanted program). This is certainly not by chance. The payload for this application never goes explicit on the setup stage. Instead, it gets obscurely integrated in the installers for other software such as free media tools, phony updates, browser toolbars and the like. Getting infected with WSE_Astromenda, therefore, is a matter of failing to notice some inconspicuous opt-out or sticking to the default setup on the installation wizard for those dubious applications.
Not knowing that the adware is making its way into a PC will only last until it begins playing havoc with the web browsers. Its cross-browser feature makes it compatible with Internet Explorer, Firefox and Chrome, which means none of these are resistant to this infection. The malware adds a new browser extension, Astromenda, which does not require user approval to be installed. Altering the custom Internet surfing settings is also an activity that this virus implements without asking. It changes the start page, making it point to https://astromenda.com. New tab settings get twisted in a similar fashion. The web search preferences also undergo an unauthorized transformation into the above-mentioned domain. Resulting from this, a large portion of web traffic from the compromised OS will get routed to the https://astromenda.com landing page.
These recurring redirects have a concrete reason behind them – the advertising. As you enter a random search in there, it gets you to a results page with up to fifteen sponsored links. Naturally, this is how a lot of money can be earned by the people who run the Astromenda Search campaign. That being said, you definitely do not want an app like this one operating on your computer. The bottom line is to get rid of this annoying entity and thus restore status quo in terms of the browsing preferences.
