SuperPDFSearch – What is it?

“SuperPDFSearch” search hijacker is a potentially unwanted application (PUA)1, that is spread as a plugin for your web browser. It is usually shared as an add-on for Chrome or Firefox, that helps to search some certain details, for instance, about sport events, make your browser much more safe, allow downloading of any kind of video clip, et cetera.

However, the “SuperPDFSearch” plugin is rather ineffective because all such functions are currently built-in to your web browser and/or system. Such marketing mottos are targeted at low-skilled computer users, like pensioners or schoolchildren. But occasionally even qualified users are getting caught on such an attraction. In particular cases, this hijacker is spread together with free software.
