Written by Tomas Meskauskas on
What kind of application is FestucaGlauca?
The FestucaGlauca browser extension has drawn attention during an examination of a malicious installer found on a shady website. This app can access various data, manage themes and extensions, and perform other actions within Chrome browsers. Since this app is considered malicious, users should remove it as soon as possible.
FestucaGlauca in detail
A major cause for concern with FestucaGlauca is its capability to enable the "Managed by your organization" feature in Chrome browsers. When a malicious app like FestucaGlauca activates this feature, it indicates that it gains significant control over the browser's settings and configurations (including policies).
FestucaGlauca can make unauthorized changes to a user's browser, which can detrimentally affect their online experience. It may switch the default search engine to one that promotes harmful content, redirect users to unsafe websites, display unwanted ads, collect various data, and more.
Moreover, FestucaGlauca has the capability to manage browser themes and extensions. This grants it the authority to add, disable, or remove themes and extensions, potentially disrupting the user's personalized browser settings and introducing unwanted elements.
Also, FestucaGlauca has the capacity to retrieve diverse data types, which gives rise to concerns about user privacy. This extension could potentially harvest user information such as browsing history, search queries, and even credit card details and passwords. This data might be utilized for malicious purposes, including identity theft.
It is essential to highlight that the installer used for FestucaGlauca distribution also includes the Chromstera web browser. Additionally, it might package other undesirable applications like browser hijackers or ad-supported apps. This implies that users with FestucaGlauca added to their browsers may have other unwanted programs on their computers.

How did unwanted software install on my computer?
Users may inadvertently incorporate FestucaGlauca into their browsers when they employ dubious installers downloaded from unreliable (unofficial) pages.
Furthermore, users can unknowingly install such applications while downloading software bundles that come with additional programs. Often, these bundles feature checkboxes or options that, if not unticked or changed, may lead to the installation of unwanted applications.
Additionally, users can unintentionally install unwanted applications by interacting with misleading advertisements or links. On certain occasions, malicious software disguises itself as legitimate updates, deceiving users into installing undesirable applications on their computers.
How to avoid installation of unwanted applications?
Prior to downloading any app, conduct online research to check for user reviews and feedback. Obtain software and apps exclusively from official websites or reputable app stores. When installing software, select "Custom," "Advanced", or similar settings that permit you to review the installation options. Carefully examine bundled apps or additional offers and decline unwanted ones.
Avoid clicking on links or ads, especially on dubious or untrustworthy websites. Consistently update your operating system, software, and antivirus programs. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
