What kind of application is NeriumOleander?
While examining a malicious installer, we uncovered NeriumOleander and troubling activities conducted by this browser extension. These actions involved adding the "Managed by your organization" feature to the Chrome browser and accumulating various data. Consequently, individuals who have added NeriumOleander to their browsers should promptly remove the extension.
NeriumOleander in detail
NeriumOleander seeks permission to access and modify data on all web pages, as well as to manage applications, extensions, and themes. While such extensive access can serve valid purposes, it also brings potential risks into focus, underscoring the importance of exercising caution and comprehending the potential outcomes.
When a shady extension, such as NeriumOleander, asks for such permissions, it should raise concerns about possible malicious intentions. Providing such broad access can result in various problems, including the potential for data theft, relinquishing control over your browser, and the installation of extra, undesirable, or harmful software.
NeriumOleander can jeopardize sensitive data, inject unwanted advertisements, disrupt the browsing experience, and bring about other undesirable consequences. Additionally, our investigation revealed that the installer responsible for distributing NeriumOleander includes supplementary, undesirable software components like the Chromstera browser.
It is crucial to underscore that programs similar to NeriumOleander may come bundled with adware, browser hijackers, and other undesired applications. In certain instances, the installers disseminating these programs might contain hidden ransomware, Trojans, cryptocurrency miners, and other malware.

How did NeriumOleander install on my computer?
The NeriumOleander application is typically distributed through a malicious installer discovered on unreliable websites. When users proceed with the installation instructions, it sets up both NeriumOleander and Chromstera on their devices.
Furthermore, engaging with deceptive pop-ups, advertisements, or hyperlinks can result in the inadvertent installation of undesired applications. Additionally, users may encounter questionable apps on third-party stores, websites that advertise free software downloads, third-party download managers, torrent sites, etc.
How to avoid installation of unwanted applications?
Exclusively obtain software and applications from reputable sources, such as official websites and app stores. Steer clear of shady websites, particularly those peddling cracked or pirated software. Exercise caution during the software installation process and meticulously examine the installation choices. Refuse proposals to add or install supplementary software by deselecting checkboxes or opting for the "Advanced," "Custom," or equivalent settings.
Do not interact with pop-up advertisements and other content delivered by questionable websites. Regularly assess the software installed on your computer, and remove any programs that you no longer require or have confidence in. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
