PDF Mac Master – a potentially unwanted app that offers PDF converting function, but also injects intrusive ads

PDF Mac Master

PDF Mac Master is another deceptive ad-supported program that uses its “useful features” to trick gullible users. This one offers to manage and view PDF files[1] on Mac computers, although a Windows version is also available. The app belongs to a widespread adware family known as Install Core – its versions are known to be spread via software bundles and spam users with sales coupons, banners, pop-ups, deals, offers, and other ads.

To make matters worse, the so-called PDF Mac Master virus might be difficult to eliminate in a regular way, as it might place login items or establish new profiles on the macOS. In the background, the application would record users' online behavior in order to produce targeted advertisements, increasing profits for the developers.

Optimization If your system still runs slow or worse after you terminate all the unwanted programs and malware, you can employ automatic repair tools to increase its performance – we recommend using ReimageIntego

You might have encountered PDF Mac Master on its original website, or maybe it came from the Internet without permission. In most cases, the app can be seen on most popular third-party software distribution websites, although it is not the tool users come for. Instead, PDF Mac Master comes as an optional component within a single application package, resulting in unintentional installation.

However, no matter how the infiltration happened, once this program is installed on a user's computer, it launches automatically. Afterward, the unwanted app will perform unwanted activities, such as display annoying advertising and redirect to ad-filled and suspicious sites.

There is a big chance that your computer screen will always be overloaded with intrusive pop-ups and pop-unders unless you perform the PDF Mac Master removal. Frequent advertising might start interrupting your browsing activity and even slowing down Google Chrome, Mozilla Firefox, or whatever another browser you are using. Besides, since the app injects ads into search results, you might struggle to find relevant information as you used to, and instead would visit sponsored sites that directly benefit the app's creators.

Nevertheless, PDF Mac Master adware might redirect you to different websites some of which might even include hazardous content. Usually, redirects will take you to pages such as:

  • Websites that advertise tech support scams or fake system optimizers;
  • Phishing sites that might include virus-related content;
  • Pages that are promoted by developers and advertise dubious products, services, etc.

Due to all beforementioned reasons, we recommend you remove PDF Mac Master from your computer system and clean web browsers that were affected by it. You can complete the process by installing reliable anti-malware tools and fixing the damage by using ReimageIntego or similar programs. However, you can feel free to look through the manual removal – you can find steps displayed below this article.

Precautionary measures are necessary if wanting to avoid adware infections

According to IT researchers from site[3], potentially unwanted programs, including adware-related ones, have more than one distribution technique. These methods are:

  • Bundling. When a PUP installs secretly with regular software from the web;
  • Rogue sites. When you accidentally start the installation of a PUP by clicking on a link on a dubious website;
  • Original downloading websites. Some ad-supported programs have their own pages where users can download the PUP by themselves.

To avoid adware[4], you need to choose the Advanced installation option and regularly check all incoming downloads. Moreover, you have to stay away from all dubious websites as far as possible and not click on any questionable content you overcome on the Internet. Finally, be careful if you have entered an adware-promoted website. Better close it and try not to get tricked by its promising look.

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.
