What is PDFSearchz

PDFSearchz is another rogue search engine that should be avoided by users. The installation algorithm is similar to its clones – adding a browser-based extension to change search settings. PDFSearchz can be extremely annoying by many means – redirecting to unwanted pages, showing ambiguous ads, and other intrusive actions that may disrupt your experience. These programs are known as browser hijackers and can drop the performance of your PC significantly. This is because they are poorly-optimized and require a lot of resources to run in the background. The rogue search engine (pdf-searchz.com) is not capable of generating unique results on its own, therefore, it mimics legitimate engines (Yahoo, Google, Bing) to show queries from them. We do not see any value in PDFSearchz and advise you to delete it from your computer as soon as possible. Browser hijackers are especially sticky not allowing users to disable or remove them completely. However, with the help of thorough instructions located below, you will be able to do so very easily.

How PDFSearchz infected your computer

Browser hijackers are usually found lurking inside freeware repacks and installation kits. Once users execute the downloaded setup, they rush through multiple steps not checking them whatsoever. This is a mistake because there are certain sections (e.g. Advanced and Custom) that can include additional offers. Note that contained offers can be claimed to be useful, but this is an advertising trick meant to tantalize people into installing the product. Thus, we recommend you find and deselect such offers unless you want to undergo a stream of unwanted content in your browser. Go through our guide to learn how to secure yourself from such threats in the future.
