InstallBrain is part of a software bundler program associated with various browser plug-ins and add-ons from the Perion Network software company. When installed, the application is essentially an updater service that will run in the background as 'ibsvc.exe' and periodically download and install updates for the associated browser components.
The add-ons maintained by InstallBrain vary in function, but have reportedly silently reset the browser homepage and modified the search engine settings and/or search results. If the user elects to remove the components, the related InstallBrain program should also be uninstalled.
As of early October 2013, some InstallBrain installers have shown code similarity to Trojan-Downloader:W32/Mevade; these installers are identified with the detection name Trojan:W32/Installbrain.[variant].
