How to get rid of the MalusDomestica malicious extension
Written by Tomas Meskauskas on
What kind of application is MalusDomestica?
The MalusDomestica browser extension has come under scrutiny following an analysis of a malicious installer discovered on an untrustworthy website. This extension has the capability to access a wide range of data, control themes and extensions, and execute other functions within Chrome browsers. Given its malicious nature, it is imperative for users to remove this app immediately.
MalusDomestica in detail
MalusDomestica has the ability to activate the "Managed by your organization" feature in Chrome. This feature is typically used by legitimate organizations to apply specific policies and configurations to Chrome browsers across their network.
When MalusDomestica activates the "Managed by your organization" feature in Chrome, it can lead to several consequences, including loss of control over browser settings, privacy concerns due to data tracking, increased vulnerability to online threats, performance issues, difficulty in restoring the original settings, and more.
Also, MalusDomestica can read and modify data on the web pages users visit. Such capabilities open the door to various risks. MalusDomestica can potentially steal sensitive information, intercept login credentials, or manipulate the content of trusted websites to deceive users. This compromises user privacy and exposes them to potential fraud, scams, and identity theft.
Furthermore, MalusDomestica can manage themes and extensions in Chrome browsers. It may replace trusted extensions with malicious counterparts or disable security-related ones, making the user's browsing experience vulnerable to threats. It can also introduce unwanted themes or alter the appearance of the browser, affecting usability.
It is crucial to emphasize that the installer used to distribute MalusDomestica includes the Chromstera web browser and potentially other unwanted applications, such as browser hijackers or ad-supported software. It means that users with MalusDomestica on their browsers might unknowingly have additional undesirable programs installed on their computers.

How did unwanted software install on my computer?
One way to unknowingly add MalusDomestica to a browser is through a malicious installer hosted on a shady website (a screenshot of such a page is provided below). Also, some software installers, especially free or freeware applications, include bundled browser extensions like MalusDomestica as part of their installation process.
Users may inadvertently add these extensions if they do not carefully read and customize the installation options. In other cases, users inadvertently add or install unwanted apps via deceptive ads, pop-ups, fake software updates, P2P networks, etc.
How to avoid installation of unwanted applications?
Download extensions (or other programs) only from official app stores or websites. Exercise vigilance during software installations, selecting custom options to uncheck bundled software. Routinely inspect and delete unused or suspicious extensions from browsers. Avoid interacting with ads, pop-ups, and links on questionable websites.
Do not allow suspicious sites to send notifications. Use reputable antivirus or anti-malware software. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
