Remove PDF Mac Master Adware (Mac)

What is PDF Mac Master Adware (Mac)?

PDF Mac Master Adware (Mac) is a deceptive program that advertises itself as PDF viewer for Mac computers. It’s similar to such PUPs as Mac File Opener and MyMacUpdater. It’s classified as a potentially unwanted program (PUP) and adware because it can install without explicit permission and fills the screen with advertisements. It’s not a dangerous program exactly, as it does not intend to do damage to your computer. Adware mainly aim to make revenue by exposing the user to advertisements, so it’s not created to do harm. However, adware generated ads are not always safe and may expose to unreliable or outright malware content. It’s also incredibly annoying because ads will appear everywhere and interrupt regular browsing.

It’s highly doubtful you downloaded this PUP yourself because there are countless PDF readers for Macs, and chances of you stumbling upon this one are low. The more likely way you got it was via freeware bundles. Freeware is often used to spread unwanted programs because the method allows PUPs to be installed without user permission. Unwanted programs are basically added to freeware as extra offers which you need to deselect. We will explain how to do this in the following section.

If you are in need of a PDF reader, you can certainly find better options out there. Ones that will not expose you to possibly dangerous advertisements. So if you notice an increase in advertisements since this PUP installed, we suggest you remove PDF Mac Master Adware (Mac).

Adware distribution

Adware often spreads via the bundling method. It comes attached to freeware as an extra offer and is preselected to install alongside. The offers are also hidden, so if users rush through installations they would not notice anything attached. This happens quite often so it’s necessary to pay attention to how you install freeware. During freeware installation, opt for Advanced (Custom) settings. Those settings will make all offers visible and you will be able to deselect them. Unchecking the offers is all you really need to do. After you have done that, you can continue installing the program. Some of those offers might seem useful enough to install but if you do see one that you’d like to have, first do some research about it. Otherwise, you will quickly fill your computer with junk programs and will later have to waste time uninstalling them.

What does it do?

The program is advertised as PDF reader for Macs, and it may work as it promises. However, it will also show you banners, generate pop-up and pop-under ads, as well as redirects. It may not matter which browser you are using, as it would probably affect Google Chrome, Mozilla Firefox and Safari. The ads can also be dangerous in addition to being annoying, so it would be best if you did not interact with any of them while adware is present on your system, no matter how tempting they may be.

You should be particularly careful of advertisements that offer you software. Such ads could be concealing malware as a legitimate program download. Programs should never be downloaded from advertisements because it’s not safe. Instead, you should opt for official sources. And downloading should only come after you have looked into the program and made sure it’s safe. Fake update notifications could also be spreading malware. You might be familiar with this as malicious ‘You need to update Adobe’ ads are pretty common. Legitimate programs will not push update notifications via your browser, so only download updates from official sources.

You could also encounter various scams that aim to get your personal information. Such scams would pop-up because adware is installed, and claim that you have won something, usually an iPhone or a Samsung smartphone. The ad would claim that you have been chosen to participate in a survey and if you are successful, you would get the prize. When you complete the survey, you would be asked to pay a small fee to get the prize, as well as provide your personal information. Such scams have been around for years so it’s unlikely you have never encountered one. They are never real, and are simply trying to get your personal information as well as money.

Obviously, we cannot force you to delete PDF Mac Master Adware (Mac). And since it’s not malware, we can’t even strongly suggest it. But if you have noticed an increase in advertisements since this extension has been installed, it may be best to get rid of it.
