PDFConvertersSearch browser hijacker removal instructions
What is PDFConvertersSearch?
The PDFConvertersSearch browser hijacker promotes pdfconverters-search.com (the address of a fake search engine). Typically, apps of this type hijack browsers by changing certain settings. Commonly, they gather browsing-related and other information. Apps of this type are categorized as potentially unwanted applications (PUAs), since most users download and install them unintentionally.
Generally, browser hijackers promote fake search engines by assigning their addresses as the default search engine, homepage, and new tab. In this way, they force users to visit a specific address when they open a hijacked browser, new tab, or enter search queries into the URL bar. PDFConvertersSearch changes the aforementioned settings to pdfconverters-search.com. It is classified as a fake search engine, since it displays results generated by Yahoo and simply redirects to search.yahoo.com. Most browser hijackers prevent users from removing the fake search engine from browser settings by reassigning the URL after each attempt to modify it. Therefore, pdfconverters-search.com can be removed from settings only when PDFConvertersSearch is no longer installed. Browser hijackers also collect browsing data such as IP addresses, geolocations, addresses of visited pages, entered search queries, and other information relating to users' browsing habits. Some browser hijackers are capable accessing sensitive, personal details as well. The data might be sold to third parties (potentially, cyber criminals) or misused to generate revenue in other ways. In such cases, users might become victims of identity theft, experience problems relating to online privacy and web browsing safety. These are just some reasons why browser hijackers should never be downloaded or installed. If PDFConvertersSearch is already installed, remove it immediately.

Some more examples of browser hijackers are SearchConverterHD, MyShortcutTab and Mountains.

In fact, browser hijackers promote fake search engines and collect data. These apps are useless and can cause serious problems.
How did PDFConvertersSearch install on my computer?
Commonly, developers distribute unwanted apps by including them into the set-ups of other programs as 'additional offers'. This distribution method is called "bundling". Typically, information about included apps can be found in "Custom", "Advanced" and other similar settings of the download and/or installation set-ups, however, many users fail to check and change these settings. By leaving them unchanged, they agree by default with offers to download and install additionally-included apps. PUAs also infiltrate by clicking deceptive advertisements that run certain scripts.
How to avoid installation of potentially unwanted applications
Avoid unofficial websites, Peer-to-Peer networks (torrent clients, eMule), third party downloaders, and third party installers. Use official pages and direct links. Check all "Custom", "Advanced" and other settings and decline offers to download or install PUAs. Do not click ads that are displayed on dubious pages (e.g., on those relating to gambling, adult dating, pornography). These ads can execute scripts to download or install unwanted software. Remove any unwanted apps (extensions, plug-ins, add-ons) installed on the browser immediately. The same should be applied to programs of this kind that are installed on the operating system. If your computer is already infected with PDFConvertersSearch, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this browser hijacker.
