PDFConverterSearchOnline – What is it?

“PDFConverterSearchOnline” search hijacker is a potentially unwanted application (PUA)1, that is distributed as a plugin for your web browser. It is usually advertised as an add-on for Chrome or Firefox, that assists to search some special details, for instance, about sport events, make your browser a lot more safe, allow downloading of any kind of web video, and so on. Also, this app adds the “Managed by your organization” feature (on Chrome browsers).

Nonetheless, the “PDFConverterSearchOnline” plugin is rather useless since all such features are already built-in to your web browser and/or Windows. Such advertising and marketing slogans are targeted at low-skilled computer users, for example, pensioners or schoolchildren. However occasionally even experienced users are getting caught on such an attraction. In specific situations, this hijacker is spread together with free apps.
