How to remove 1stBrowser

What is 1stBrowser

1stBrowser is a chromium-based web browser that claims to enhance the Internet browsing experience by allowing users to personalize their settings and easily access their favorite sites. Despite its appealing features, this application is classified as a potentially unwanted program (PUP) due to its deceptive installation methods and intrusive behavior. Often bundled with other software, it may install without users’ consent, leading to unexpected redirects to isearch.tinyresults.com, which disrupts normal browsing activities. Furthermore, 1stBrowser gathers various data, including IP addresses and browsing habits, which raises significant privacy concerns despite claims that the information is non-identifiable. Users may find themselves inundated with unwanted advertisements and tracking, as the primary purpose of this adware-type application is to generate revenue for its developers. To mitigate these issues, it is crucial for users to be vigilant during installations and to actively remove this unwanted application from their systems when detected.

How 1stBrowser infected your computer

1stBrowser infects computers primarily through deceptive installation practices, typically bundled with other software during the download process. Users often unknowingly consent to its installation by opting for default settings instead of choosing custom or advanced options, which would allow them to review and decline additional software offers. Once installed, 1stBrowser modifies browser settings to redirect users to isearch.tinyresults.com, significantly disrupting their browsing experience. This potentially unwanted program (PUP) also tracks internet activity, collecting non-personally identifiable information such as IP addresses and browsing habits, which it may share with third parties. The adware nature of 1stBrowser means it is designed to generate revenue through intrusive ads, further compromising user privacy and system performance. Consequently, users are advised to remain vigilant during software installations and to regularly scan their systems for unwanted applications.
