PDF King is a file converter and a browser hijacker[1] offered for macOS users. Unfortunately, just as many other programs of this type, its adverse effects on the system outshines the positives, and users end up with cluttered computers and slow browsers that continually display pop-up ads, banners, deals, coupons, sponsored links, and similar content. PDF King is available as a standalone app from the official website, as well as a browser extension for Google Chrome, Mozilla Firefox, Safari, and other browsers. However, that is not the method that is mostly used for its propagation, as software bundling is the primary one. Created by Tabatoo Ltd., this app is something you would not want to keep on your macOS, especially when it gets installed with other software.

As soon as the PDF King app or the browser plugin is installed, it modifies web browser settings, setting new tab address and homepage to, or a similar one. Upon using this search engine, users are redirected to – a trusted search engine by Yahoo. However, because users are redirected several times when searching, they can notice the sponsored links on the top of the search results, which would usually not be there if using Yahoo directly.

And that is precisely how PDF King authors earn money. They rely on users clicking on these links so that sponsored websites would get more traffic, increasing the search rank significantly within the search engine. Nevertheless, the sites that users could be led to might be dangerous, and malware infections or stolen personal data could become a reality. In order to void that in the future, users should take care of prompt PDF King removal.

Software bundling is legitimate but unfair software distribution method that tricks many users

Potentially unwanted applications usually get installed together with other software that was downloaded from the internet. Unfortunately, many regular users are not aware that software is bundled, especially free one. While initial installers of some apps might be free of optional components, certain third-party sites might add additional programs in order to profit from installations made.

To avoid potentially unwanted programs like adware, browser hijackers, and other bloatware, experts[3] recommend the following:

  • Avoid third-party installers and sites – pick official sources instead;
  • Always read through ToS and Privacy Policy, or at least the most important parts of it;
  • Never skip steps by clicking the “Next” button without looking;
  • Select Advanced or Custom installation mode when prompted. Recommended or Quick settings are often the mode where all the additional programs are hidden;
  • Uncheck all apps like PDF creators, media players, installation managers, and similar useless software

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
