What is BubblePDF?
BubblePDF promotes fake search engine addresses (hp.bubblepdf.com and find.bubblepdf.com) by changing certain browser settings. It can also access data on the system. Generally, users do not download or install browser hijackers intentionally and, for this reason, apps such as BubblePDF are classified as potentially unwanted applications (PUAs).
Typically, apps such as BubblePDF hijack browsers, changing their settings such as the address of a new tab, homepage, and default search engine. This particular app assigns them to hp.bubblepdf.com or find.bubblepdf.com. Users cannot undo the changes as long as the browser hijacker (in this case, BubblePDF) is installed on the browser and/or computer.
Therefore, users are forced to visit a specific address when they search via the URL bar or simply open a new browser window or tab. Note that hp.bubblepdf.com and find.bubblepdf.com redirect users to search.yahoo.com and simply display results generated by Yahoo.
Browser hijackers also access and 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.
Furthermore, the information can be misused by the developers to generate revenue. For example, it could be misused by selling it to third parties (potentially, cyber criminals). This can lead to problems relating to online privacy, browsing safety, and some users might even become victims of identity theft. Therefore, browser hijackers should never be downloaded or installed.

Other examples of apps similar to BubblePDF are SearchAnyGame, Search Omiga and SearchRadioStation. The main purpose of these apps is to change browser settings and promote fake search engines, however, they often collect data as well. In any case, browser hijackers are useless and can cause serious issues.
If BubblePDF or other apps of this type are installed on the browser and/or computer, remove them immediately.
How did BubblePDF install on my computer?
PUAs are often downloaded/installed together with other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions is called "bundling".
By rushing through download/installation of software (e.g. ignoring terms, skipping steps and sections, using "Quick/Express" settings, etc.) many users risk unintentionally allowing bundled content into their devices. Intrusive advertisements proliferate PUAs as well.
When clicked, the ads can execute scripts to download/install these applications without users' permission. Some PUAs have "official" download web pages from which they can be downloaded.
How to avoid installation of potentially unwanted applications
Download software and files from official websites and via direct links. It is not safe to use torrent clients, eMule (or other Peer-to-Peer networks), third party downloaders, unofficial websites or other sources of this kind. Avoid third party installers. Check "Advanced", "Custom" and other settings, and decline offers to download or install unwanted software.
Do not click ads that are displayed on dubious websites, since they can open other untrusted websites or even cause unwanted downloads and installations. Remove any unwanted, suspicious applications (extensions, add-ons, and plug-ins) that are installed on the browser.
The same should be applied to programs of this kind that are installed on the operating system. If your computer is already infected with BubblePDF, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
