How to remove Chromstera

What is Chromstera

Chromstera is a potentially unwanted application (PUA) that is based on Chromium, an open-source web browser project. It disguises itself as a legitimate browser, but it is actually a browser hijacker. This means it can modify your browser settings without your consent, such as changing your homepage or search engine preferences, redirecting your searches, and displaying unwanted ads. While these activities can be disruptive and frustrating, they generally don’t cause direct harm to your computer or data. However, Chromstera’s actions can still be detrimental to your online privacy and browsing experience, as it may collect your browsing data to serve targeted ads. Chromstera is considered an unwanted application due to its intrusive behavior and potential privacy risks. It can make undesirable changes to your browser, such as modifying your homepage or search engine preferences, redirecting your searches, and displaying unwanted ads. These activities can disrupt your online experience and slow down your computer’s performance.

How Chromstera infected your computer

Chromstera typically infiltrates your system alongside other unwanted or potentially malicious software. It is often bundled with free software downloads, and users may unknowingly install it while installing other programs. This is a common distribution strategy used by potentially unwanted programs (PUPs) like Chromstera. Once installed, Chromstera can modify your browser settings, redirect your searches to its own search engine, and display intrusive advertisements. It can also collect sensitive user data, such as visited URLs, viewed webpages, searched queries, IP addresses, Internet cookies, usernames/passwords, personally identifiable details, and credit card numbers. This collected data can then be shared with or sold to third parties, potentially including cybercriminals.
