The ViewPDF Web-browser add-on is yet another bogus application that does not have your best interest in mind. This browser add-on targets users who are looking for PDF files. The ViewPDF application presents itself as a useful tool that will allow its users to search the Web for PDF files. While this property may seem useful to some, we can assure you that you do not need third party software to look for a specific filetype. Regardless of what search engine you use, whether it is Google, Bing, Yahoo, DuckDuckGo, or any other, you can set the search engine to look for a specific filetype via its advanced search options.
Alter Users’ Default Search Engine
Apart from the fact that the ViewPDF add-on does not offer any unique tools, it may also meddle with your Web browser settings. This is shady behavior that should not be tolerated. Some users who have installed the ViewPDF add-on have reported that this application has altered their Web browser preferences and set the Pdfsrch.com search engine as default without asking for their consent. This is not considered as malicious behavior, but the results delivered by the Pdfsrch.com search engine may not be relevant or may give priority to sponsored content.
The activity of the ViewPDF add-on is not associated with any malware but can nonetheless hinder your Web browsing experience. No legitimate application would apply changes to your Web browser without consulting you first. This is why the ViewPDF add-on is classified as a PUP (Potentially Unwanted Program). It is advisable to remove it from your system immediately. You can either do this manually via your Web browser settings or using a reputable cybersecurity application. The latter is preferred as the anti-malware tool will also make sure to wipe out any leftover files that may remain on your system.
