What is PDFdefault ads?

PDFdefault ads appear on your screen when you have the PDFdefault adware installed on your PC. It is only logical. These ads show up on the Chrome, Firefox, and Internet Explorer browsers.

Your best option right now is to remove PDFdefault ads from your system, and the best way to achieve that is to delete the program responsible, and every single application that might have arrived with it.testtesttest

Where do PDFdefault ads come from?

As mentioned, the ads are a direct result of having the PDFdefault adware application on your system. This program comes from the same group of developers as WebOptimum and Saver adware applications. The official website for the program can be accessed via pdfdefault.com, but it is not working at the time of writing. Therefore, it means that users do not download this adware program directly. Instead, the application clearly comes bundled with freeware and other adware.

Here we once again have to mention the importance of being attentive when you download software. You might have heard it countless of times, but the sheer amount of users who get infected with the likes of PDFdefault ads proves that users are still not careful enough when it comes to freeware. The point is that you should read every single step in the installation wizard because third-party installers often give you the choice of choosing between additional features. To put it simply, users can choose to not install such applications, but they simply miss it because they breeze through the setup, eager to use this one particular program they need as soon as possible.

What do PDFdefault ads do?

When this adware application slithers into your computer, it adds add-ons and plug-ins to all compatible browsers. The Firefox browser disables the extension automatically under the security grounds. This should be enough to convince you that there is something fishy about the program: if a reputable browser considers it to be a potential security issue, it should raise a few red flags immediately.

Of course, for the most part, PDFdefault ads are more annoying than dangerous. They will slow down your web browsing process, flooding your browser’s window with random pop-ups. However, if you look at them closely, you will see that they are not so random after all. Have you looked for a place to stay during your oncoming trip? Perhaps you see a lot of pop-ups with various hotel offers? Are these PDFdefault ads, too? Well, not so random after all, are they?

The reason these ads can provide you with relevant content is that the adware program monitors your online activities via tracking cookies. They can track what keywords you enter in your search queries and what websites you frequent on a regular basis. Once enough data is gathered, PDFdefault generates customized ads personally for you.

Why would an adware program do that? When PDFdefault ads contain target content, there is a bigger chance you would click those ads. If you click them: you will help the people behind this program make money. They usually employ the pay-per-click system to generate a financial profit. Do you get anything in return? Not really. Unless the adware program is exploited by cyber criminals, then you could definitely get a malicious infection in return. And that is definitively something you would not like to experience, right?
