How to remove PDF Mac Master from Mac?

What is PDF Mac Master?

Belonging to the InstallCore adware family, PDF Mac Master is a deceptive application that supposedly allows users to view and manage PDF files. Judging on appearance alone, PDF Mac Master may seem legitimate and useful, however, this app is categorized as a potentially unwanted application (PUA) and adware. There are three main reasons for these negative associations: 1) stealth installation without users' consent; 2) display of intrusive ads, and; 3) information tracking.

PDF Mac Master delivers coupon, banner, pop-up, and other similar advertisements. To achieve this, developers employ tools that enable placement of third party graphical content on any visited websites. Therefore, intrusive ads often conceal underlying content, thereby significantly diminishing the browsing experience. Furthermore, they might redirect to infectious websites and execute scripts that download and install malware. Therefore, clicking them is risky and can lead to computer infections. Adware-type applications such as PDF Mac Master are also notorious for information tracking. These applications often gather information such as IP addresses, website URLs visited, pages viewed, search queries, and so on. Collected data typically includes personal details that developers share with third parties (potentially, cyber criminals). These details are often misused to generate revenue. Therefore, data tracking can lead to serious privacy issues or even identity theft. You are strongly advised to uninstall PDF Mac Master adware immediately.

There are many adware-type applications identical to PDF Mac Master (including, for example, Snap Media Player, RadioSpot, Unzippy, etc.). In fact, all adware-type applications are very similar. By offering a wide range of 'useful features', these unwanted apps attempt to give the impression of legitimacy, however, remember that apps such as PDF Mac Master are designed only to generate revenue for the developers. Most deliver no real value for regular users. Potentially unwanted applications deliver intrusive advertisements and gather information relating to web browsing activity.

How did PDF Mac Master install on my computer?

PDF Mac Master has an official download website, however, it often infiltrates systems without permission, since developers proliferate it using intrusive advertisements and a deceptive marketing method called 'bundling'. Developers hide 'bundled' apps within 'Custom/Advanced' settings (or other sections) of the download/installation processes. Furthermore, many users often click advertisements, rush download/installation processes, and skip steps. This behavior can lead to infiltration of unwanted apps. In this way, users expose their systems to risk of various infections and compromise their privacy.

How to avoid installation of potentially unwanted applications?

To prevent adware infiltration, be very cautious when browsing the Internet and downloading/installing software. Intrusive ads typically seem legitimate, since developers invest many resources into their design. In fact, they redirect to dubious websites (gambling, adult dating, pornography, etc.). If you experience these redirects, eliminate suspicious applications and browser plug-ins. Select 'Custom/Advanced' settings and closely analyze each download/installation step. Opt-out of additionally-included apps and decline offers to download/install them. Software should be downloaded from official sources only, using direct download links. The main reasons for computer infections are poor knowledge and careless behavior and the key to safety is caution. If your computer is already infected with PDF Mac Master, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
