PDF Converter App browser hijacker removal instructions
What is PDF Converter App?
PDF Converter App is one of many bogus applications that supposedly provide useful features. In fact, they promote fake search engines by changing browser settings. These apps are categorized as browser hijackers and potentially unwanted applications (PUAs). PDF Converter App promotes search.pdfconverterapptab.net in this way and is installed together with Hide My Searches (also a PUA). Typically, browser hijackers change certain browser settings and gather information relating to users' browsing activity.
Most browser hijackers promote fake search engines by changing browser settings such as the address of the default search engine, homepage, and new tab. PDF Converter App assigns them to search.pdfconverterapptab.net so that users are forced to visit this URL when they open a browser, new tab or enter search queries into the URL bar. Note that, if used to search, search.pdfconverterapptab.net provides results generated by Yahoo. I.e., it simply redirects users to search.yahoo.com. Therefore, search.pdfconverterapptab.net does not generate unique results and is thus fake. To remove search.pdfconverterapptab.net from the aforementioned settings, PDF Converter App must first be uninstalled, since it prevents users from modifying the settings. Furthermore, most browser hijackers gather information such as geolocations, entered search queries, URLs of visited websites, IP addresses, and other browsing data. Developers sell the data to third parties (potentially, cyber criminals) who misuse it to generate revenue. Some of the shared data might contain personal, sensitive details. We advise that you uninstall all potentially unwanted apps, since they can cause problems relating to privacy, browsing safety or even lead to identity theft.

Easy Package Tracking, Privacy Searching and Online TV Streams are examples of other apps that are categorized as browser hijackers. These apps promote the addresses of fake search engines and collect browsing (and other) data. They are promoted as useful apps that deliver various features, however, few provide any real value. PUAs are designed only to help developers to generate revenue, and they put users at risk of various problems.
How did PDF Converter App install on my computer?
Most users end up having PUAs downloaded and/or installed when they click dubious, deceptive ads that execute certain scripts, or when developers distribute them using a deceptive marketing method called "bundling". People often download and install PUAs unintentionally. PUAs are usually included into the download/installation set-ups of regular software - related information is provided in "Custom", "Advanced" and other similar settings. Unfortunately, many people leave these settings unchanged, thereby agreeing by default with offers to download and install unwanted programs that are included in the set-ups.
How to avoid installation of potentially unwanted applications
Third party downloaders, installers, Peer-to-Peer networks such as torrent clients, eMule, unofficial websites and other similar channels should not be used to download or install software. Programs should be downloaded only from official websites and via direct links. As mentioned above, offers to download or install PUAs can often be found in "Custom" or "Advanced" options of the set-ups. Therefore, check these settings carefully and change them if necessary. Intrusive advertisements displayed on dubious web pages should not be clicked, since they often lead to dubious websites or cause download/installation of PUAs. Check for any unknown, suspicious, plug-ins, add-ons, or extensions already installed on the browser, or programs of this type installed on the operating system. Remove unwanted entries immediately. If your computer is already infected with PDF Converter App, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this browser hijacker.
