What is PC_Sustainer?

PC_Sustainer is an adware program that runs within the user's web browser and will modify various browser settings such as changing the search provider. In addition, this adware will inject display ads in the browser either by inserting new banner ads that would otherwise not be displayed on webpages viewed by the user or by adding new advertisements on top of existing ads. It will also insert hyper-text links on pages to display popup ad formats. Ads that re displayed are typically low quality and are not associated with the underlying web site the user is visiting. In many cases this adware is difficult to remove through the standard installer that is provided or will only remove some parts of the program and will not reset items such as the hijacked search and home pages.


A majority of users end up uninstalling this less than a week of it being installed.
