How to uninstall Ultra PDF Converter Plus
Written by Tomas Meskauskas on (updated)
What is Ultra PDF Converter Plus?
As its name suggests, Ultra PDF Converter Plus supposedly converts files to and from PDF format. In fact, this app promotes ultrapdfconverterplussearch.com (the address of a fake search engine) by changing browser settings. Apps of this type are categorized as browser hijackers.
They change certain settings and collect information relating to users' browsing habits. Typically, people download and/or install browser hijackers inadvertently and, therefore, they are also classified as potentially unwanted applications (PUAs).
Ultra PDF Converter Plus promotes ultrapdfconverterplussearch.com by assigning this URL as the address of the default search engine, homepage, and new tab. In this way, it forces users to visit ultrapdfconverterplussearch.com when they open a browser, new tab or enter search queries into the URL bar.
Generally, the only way to stop browsers from opening the addresses of these fake search engines is to uninstall the browser hijackers that promote them. Most browser hijackers prevent users from modifying the settings. Therefore, to remove ultrapdfconverterplussearch.com from the settings, it is necessary to first uninstall Ultra PDF Converter Plus.
As mentioned, ultrapdfconverterplussearch.com is a fake search engine - this is since it does not generate unique results and simply redirects to search.yahoo.com (provides results generated by Yahoo). Furthermore, browser hijackers record information relating to browsing activity.
For example, IP addresses, geolocations, entered search queries, addresses of visited websites, and other details. Some browser hijackers can access personal, sensitive details as well. People responsible for this software misuse the data to generate revenue, and often sell it to third parties (potentially, cyber criminals) who do the same.
PUAs cause problems relating to online privacy, browsing safety, and so on. Some users might even end up having their identities stolen. This situation can be prevented by avoiding download/installation of browser hijackers and other apps designed to track information.

How did Ultra PDF Converter Plus install on my computer?
Unwanted apps are usually downloaded and/or installed when people click deceptive ads or they download/install programs without paying attention to the settings. PUAs are often included in the set-ups of other software, a distribution method called "bundling".
This is used to trick people into downloading and/or installing various unwanted apps with other software. Generally, information about additional apps can be found in "Custom", "Advanced" and other settings of the set-ups. Many people fail to check and change the settings, thereby agreeing by default with offers to download or install PUAs.
Deceptive ads also cause download/installation of unwanted apps when they execute certain scripts, however, they cannot execute them without first being clicked.
How to avoid installation of potentially unwanted applications
Do not download or install software, especially freeware from unofficial websites, through Peer-to-Peer networks such as torrent clients, eMule, third party downloaders, installers or other tools/channels of this kind. Choose official websites and direct links.
Check all settings that are available in the download or installation setup and dismiss offers to download/install unwanted software. Do not click intrusive ads, especially if they are displayed on dubious websites - they can redirect to untrustworthy websites or cause unwanted downloads/installations.
To stop a browser from opening untrustworthy web pages and/or displaying ads, uninstall all unwanted, unknown or suspicious extensions, plug-ins and add-ons.
Also apply this to programs of this kind that are installed on the operating system. If your computer is already infected with Ultra PDF Converter Plus, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
