BubblePDF browser hijacker removal instructions
What is BubblePDF?
BubblePDF promotes a fake search engine (hp.bubblepdf.com and find.bubblepdf.com addresses) by changing certain browser settings. Also, it reads certain data. As a rule, users do not download and install browser hijackers on purpose, knowingly. For this reason apps like BubblePDF are called potentially unwanted applications (PUAs).
Typically, apps like BubblePDF hijack browsers changing their settings such as address of a new tab, homepage, and default search engine. This particular app changes them either to hp.bubblepdf.com or find.bubblepdf.com. It is common that users cannot undo such changes as long as the browser hijacker (in this case BubblePDF) is installed on a browser and/or computer. It means that users are forced to visit a certain address when they search via the URL bar or simply open a new browser window or tab. Hp.bubblepdf.com and find.bubblepdf.com are designed to redirect users to search.yahoo.com. In other words, to display results generated by Yahoo. Another reason not to have any browser hijacker installed is that such apps often are designed to collect various data. In most cases they target browsing data (e.g., geolocations, IP addresses, entered search queries, addresses of visited websites). However, some browser hijackers are capable of accessing sensitive, personal information as well. Moreover, gathered information may be misused by their developers to generate revenue. For example, it could be misused by selling it to third parties (potentially cyber criminals). This might cause users problems related to online privacy, browsing safety, some of them may even become victims of identity theft. Therefore, browser hijackers should never be downloaded and installed.

A couple more examples of apps like BubblePDF are SearchAnyGame, Search Omiga and SearchRadioStation. Typically, the main purpose of such apps is to change browser settings/promote some fake search engine. However, quite often they are designed to collect certain data as well. Either way, most browser hijackers are useless and can be the culprit of various issues. If BubblePDF or other app of this type is installed on a browser and/or computer, then it should be removed from it as soon as possible.
How did BubblePDF install on my computer?
In most cases PUAs are distributed by integrating them in download and/or installation setups of other programs. This distribution method is known as "bundling". It is common that this method is used with a purpose to deceive users into downloading and/or installing PUAs alongside with some other programs that they download and/or install intentionally. As a rule, offers to download and/or install PUAs can be declined in "Custom", "Advanced" settings of setups. However, not all users check and change those settings when they download and/or install programs. Therefore, they offers to download and/or install additionally included applications as well. Deceptive advertisements can cause unwanted downloads and installations too. Although, only when users click ads that are designed to run certain scripts.
How to avoid installation of potentially unwanted applications?
To avoid unwanted downloads, installations it is advised not to download files or programs from unofficial websites, through third party downloaders, Peer-to-Peer networks like torrent clients, eMule, and other similar channels, or install them via third party installers. Files, programs should be downloaded from official pages and via direct download links. Another important thing is to check setups for "Advanced", "Custom" and other settings and see if they include offers to download and/or install additionally included apps. Since advertisements that appear on questionable pages can be designed to open potentially malicious pages or even cause unwanted installations, they should not be clicked as well. If there are any unwanted extensions, plug-ins or add-ons installed on browser or programs of this type installed on a computer, then they should be removed. If your computer is already infected with BubblePDF, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this browser hijacker.
