BestSearchPDF – What is it?

“BestSearchPDF” search hijacker is a potentially unwanted application (PUA)1, that is spread as a plugin for your web browser. It is typically promoted as an add-on for Chrome or Firefox, that aids to search some particular details, for example, about sporting activity events, make your browser far more safe, allow downloading of any type of video clip, et cetera. Also, this app adds the “Managed by your organization” feature (on Chrome browsers).

Nevertheless, the “BestSearchPDF” plugin is pretty useless since all such features are already embedded to your web browser and/or system. Such advertising mottos are targeted at low-skilled computer users, like pensioners or schoolchildren. But frequently even qualified users are getting caught on such a lure. In certain instances, this hijacker is dispersed along with free software.
