Security professionals named the PDF Converter HD Search a PUP (potentially unwanted program) and a browser hijacker because it is designed to take over the browser and control user’s surfing preferences. The PDF Converter HD Search can sneak into the computer unnoticed due to the fact that it’s actively being promoted in free applications. It mostly aims at Google Chrome web-browser, but it is possible that it can affect other web browsers too. We recommend you to remove PDF Converter HD Search as soon as it hijacks your home page or search provider.
Most often, browser hijackers promote fake search providers by setting their address as the default search provider. In this case, the browser hijacker installs feed.pdfconverterhd.com as a search engine. This means that users whose internet browser is infected with the hijacker are forced to visit pdfconverterhd.com each time they search in the Web, open a new window or tab. And since PDF Converter HD Search is not a real search engine and does not have the ability to find the information users need, this webpage redirects the user’s web browser to the Yahoo search engine.
It is not a good idea to have an unwanted program like PDF Converter HD Search on your computer. The reason for this is simple, it doing things you do not know about. The hijacker can be used to collect your confidential data that can be later used for marketing purposes. You don’t know if your home address, account names and passwords are safe. And of course you completely don’t know what will happen when you click on any advertisements on the PDF Converter HD Search web-site.
