PDFSearchHQ

PDFSearchHQ is a browser add-on that poses a useful utility meant to help you find online documents, presentations and other relevant content. However, PDFSearchHQ is considered to be a Potentially Unwanted Program (PUP,) and installing it is usually going to cause undesired changes to your Web browser's configuration.

The changes linked to PDFSearchHQ are not harmful, but they may hinder your Web browsing experience by forcing you to use alternative websites found at Portal.pdfsearchhq.com and Feed.pdfsearchhq.com – these will be set as the default new tab and search engine, respectively.

If your Web browser is redirecting you to PDFSearchHQ's URLs, then you should consider removing this Potentially Unwanted Program (PUP) in order to get rid of the changes it made. To do this, you should run a computer security tool, since they also are capable of removing Potentially Unwanted Programs.
