Rts.dsrlte.com browser hijacker removal instructions

What is Rts.dsrlte.com?

Rts.dsrlte.com is a browser hijacker that is promoted through an application called AppStein. The software modifies users' Internet browser (Internet Explorer, Google Chrome, and Mozilla Firefox) homepage and default search engine settings by assigning them to certain websites (for example, Rts.dsrlte.com). This website then redirects Internet users to Yahoo.com. In addition, AppStein 'protects' these settings by preventing further user-changes. Developers of this browser hijacker state that AppStein is a useful desktop application helping to maintain users' selected browser settings. This application, however, adds no real value and is created to redirect Internet users to Rts.dsrlte.com (or other websites) and prevents further modification of Internet browser settings by the user.

Unwanted redirects to certain websites are applied to generate revenue from users who click deceptive ads or use the dubious Internet search engine presented by these websites. Be aware that, as well as generating unwanted browser redirects, AppStein tracks users' Internet browsing activity by recording web pages visited, user languages, Internet Protocol (IP) addresses, geographic locations, and search queries entered. The presence of AppStein on your system can lead to malware infections and privacy issues, and therefore, you are advised to eliminate this potentially unwanted application and remove browser redirects to rts.dsrlte.com.

AppStein adware is similar to other browser hijackers, which modify users' Internet browser settings. Examples include trovi.com, default-search.net, and hao123.com. Commonly, users install this browser settings-changing adware when downloading free software. Today, most freeware download websites employ 'download clients' - small programs offering installation of advertised browser plug-ins together with the chosen free program. Not paying close enough attention to the download steps can result in adware infections, and therefore, when downloading free software, be attentive - opt-out of installation of any advertised browser extensions by clicking the 'decline' button. Computer users who experience browser redirects to rts.dsrlte.com should use this removal guide to eliminate adware from their operating systems.
