DataSearchLauncher

DataSearchLauncher is an annoying Mac program whose installation may redirect all of your online searches through a 3rd-party service that eventually takes you to Yahoo Search. The DataSearchLauncher is categorized as a browser hijacker, so you should not see it as a security concern – however, you must not forget that browser hijackers may take you to non-trustworthy Web destinations occasionally. They may apply undesired changes to your Web browser's configuration.

If your Mac Web browser has been misbehaving recently, then it is very likely that a browser hijacker like DataSearchLauncher may be responsible for the issue. It is recommended to run a Mac a security scanner, which will help you identify and remove intrusive software like the DataSearchLauncher hijacker.
