GreatSearchPdf – What is it?

It is typically marketed as an add-on for Chrome or Firefox, that helps to browse some special info, for instance, about sport events, make your browser much more secure, enable downloading of any kind of video, et cetera.

Such advertising and marketing mottos are targeted at low-skilled computer users, like pensioners or schoolchildren. But often even skilled users are getting caught on such a lure. In certain instances, this hijacker is dispersed together with free tools.
