How to remove PolianthesTuberosa malicious extension
Written by Tomas Meskauskas on
What kind of application is PolianthesTuberosa?
After careful examination, it has been determined that PolianthesTuberosa is an untrustworthy application capable of causing various harms to users. PolianthesTuberosa can access diverse data, control extensions, and themes, and enable the "Managed by your organization" feature (in Chrome and Edge browsers).
PolianthesTuberosa in detail
When users see the "Managed by your organization" feature in a browser, it means that certain settings or policies on the browser are being controlled by an external entity, such as an IT department or a software application. If an app like PolianthesTuberosa enables this feature, potential damages include compromised security, unauthorized access to sensitive data, and alterations to browser settings.
Also, PolianthesTuberosa can read and change data on all pages. This level of access means the malicious app can potentially extract sensitive information from any webpage, including login credentials and personal data.
Moreover, the ability to modify data on web pages opens the door to various attacks, such as injecting malicious content, redirecting users to phishing sites, or manipulating online transactions. Another reason to remove PolianthesTuberosa is that it can manage themes and extensions.
By manipulating themes, the malicious app can potentially create deceptive interfaces or modify the browser's appearance in a way that may trick users into interacting with harmful content. Additionally, having control over extensions allows the app to add, disable, or modify them, posing a risk of introducing further security vulnerabilities or unwanted functionalities.
Finally, PolianthesTuberosa is not the only unwanted app included in the installer used to distribute it. It has been found that PolianthesTuberosa is bundled with the Chromstera browser and possibly other unwanted apps (e.g., browser hijackers or adware).

How did unwanted software install on my computer?
PolianthesTuberosa is distributed via a malicious installer found on an unreliable webpage. After downloading and running the installer and upon completing the installation process, PolianthesTuberosa is integrated into the user's browser.
Furthermore, applications of this kind may find their way onto devices via deceptive advertisements, downloads obtained from non-official app stores, peer-to-peer (P2P) networks, and similar avenues
Another common strategy for disseminating questionable applications involves bundling. In these cases, installers include extra applications that get added or installed when users finalize installations without adjusting the default settings, such as "Custom" or "Advanced" options.
How to avoid installation of unwanted applications?
Prior to downloading any application, it is advisable to review user feedback and ratings. Opt for trustworthy and official sources, such as official websites and app stores, for software downloads. When installing software, carefully examine the installer and unselect any undesired apps included.
Exercise caution when encountering enticing offers or promotions that encourage app downloads. Avoid placing trust in questionable applications and pop-ups. Regularly assess the apps installed on your devices. Employ reliable security software and conduct routine scans of your computer.
If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
