How to remove PinusSylvestris malicious application
Written by Tomas Meskauskas on
What kind of application is PinusSylvestris?
PinusSylvestris is an untrustworthy browser extension that can read various data and have other impacts on Chrome (and Edge) browsers. The discovery of this app occurred while inspecting a malicious installer downloaded from a dubious website. It is highly recommended not to trust PinusSylvestris and similar apps.
PinusSylvestris in detail
PinusSylvestris is a malicious application with the capability to access and retrieve a user's browsing history. This invasive behavior raises significant concerns about user privacy, as information such as visited websites and personal preferences could be compromised.
Additionally, the app can manage various aspects of the Chrome browser, including apps, extensions, and themes. This level of control allows PinusSylvestris to manipulate the browser environment, potentially adding or removing extensions and altering themes. These actions can result in unexpected changes, disrupt normal browsing activities, and expose users to security threats.
In addition to its actions within the Chrome browser, PinusSylvestris extends its impact by activating the "Managed by your organization" feature in both Chrome and Edge browsers. This means that users may lose the ability to modify critical browser settings, including security and privacy configurations, subjecting them to potential restrictions imposed by PinusSylvestris.
It is also important to mention that the installer distributing PinusSylvestris contains other unwanted software, such as the Chromstera browser. It is also possible that the installer contains adware, browser hijackers, or similar questionable apps.

How did unwanted software install on my computer?
PinusSylvestris is distributed via installer hosted on a dubious page and becomes added to a web browser after completing the installation. Also, apps of this kind can be installed via deceptive ads, drive-by downloads, software bundles, etc. Sometimes, users obtain such apps via P2P networks, third-party downloaders, free file hosting sites, etc.
How to avoid installation of unwanted applications?
It is advisable to be discerning about the sources from which they download software, apps, or files. Stick to official websites and well-established app stores when obtaining applications. Avoid clicking on pop-up ads, especially those from dubious websites, as they can lead to potentially harmful downloads.
