Written by Tomas Meskauskas on
What kind of program is PachycephalosaurusWyomingensis?
After a review, it has been established that PachycephalosaurusWyomingensis is a shady browser extension distributed via a malicious installer. PachycephalosaurusWyomingensis raises concerns due to its ability to activate the "Managed by your organization" feature in Chrome and Edge browsers, manage themes and extensions, and read various data.
PachycephalosaurusWyomingensis in detail
The ability of PachycephalosaurusWyomingensis to activate the "Managed by your organization" feature in Chrome and Edge browsers raises significant concerns for users. When an extension gains control over this feature, it essentially means that the extension has the capability to exert a higher level of control and influence over the browser settings, configurations, and policies.
The "Managed by your organization" feature is intended for use by organizations to enforce policies across multiple devices. When a malicious extension activates this feature, it can implement policies that may compromise user privacy and security. This could involve the forced addition of other extensions, browsing behavior modification, or even traffic redirection.
Also, enabling the "Managed by your organization" feature allows PachycephalosaurusWyomingensis to modify browser settings without the user's direct consent. This can include changes to security settings, homepage preferences, default search engines, and more.
PachycephalosaurusWyomingensis's capability to read various data implies that it might access sensitive information stored within the browser. This could include browsing history, login credentials, personal information, and more. Users are at risk of privacy violations, as the extension may exploit this data for malicious purposes or share it with third parties.
The extension's ability to manage themes and other extensions could lead to the addition of other malicious extensions or manipulation (e.g., removal) of existing ones, leading to potential vulnerabilities and exposing users to security threats.
PachycephalosaurusWyomingensis is bundled with the Chromstera browser and possibly adware, browser hijackers, or other dubious apps. Thus, users with PachycephalosaurusWyomingensis added to their browsers should scan their computers for other threats and remove them.

How did unwanted software install on my computer?
One common method involves bundled software packages, where users download seemingly legitimate programs with additional unwanted applications included in the installation. Often, these bundled apps are pre-selected for installation by default, and users may overlook or not notice them during the installation process.
Additionally, misleading advertisements and fake download buttons on websites can trick users into downloading and installing unwanted apps. Moreover, users may fall victim to social engineering techniques, such as phishing emails or fake software updates.
How to avoid installation of unwanted applications?
When acquiring applications, it is advisable to stick to reputable websites and authorized app stores. Exercise caution when considering software downloads from unfamiliar or suspicious sites. Take a moment to review the installation settings, especially options like "Advanced" and "Custom" or similar, to detect and reject any bundled unwanted applications that may accompany the desired software.
Maintain your system's security by consistently updating the operating system and installed software. Augment your defense measures by installing a trustworthy security tool. Exercise skepticism towards pop-ups, advertisements, and content on dubious websites, and refrain from accepting notifications from such sites to enhance your online security.
If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
