Fortunately, there is a silver lining. Adware pests are relatively easy to remove but you have to act fast. PDF Viewer will eventually go out of control and then it might be too late to stop it.

The parasite even blocks commercials by its competitors so its ads are the only ones you see. So, you see coupons, banners, deals, offers, pop-ups, video ads, and whatever else you can think of all the time. All sponsored by the PDF Viewer.

What is more interesting though is that all of the advertisements look like they have been selected for you and you only. They are related to your online habits, likes, preferences and even search queries. How is that possible, you may ask? Well, you will not like the answer. PDF Viewer knows that you like because it spies on you. It monitors your every online move and then uses this information to select ads that you would find appealing.

Why does it go through so much trouble only to make you click on an ad? Because every time you click, the crooks behind PDF Viewer gain money. They are using the pay-per-click mechanism to make effortless money. What is more, with every single click you are risking downloading more infection on your machine.

But do you know how PDF Viewer sneaked in undetected? Do you know how infections travel the web and, most importantly, how to protect yourself? All parasites rely on tricks to slither on victims` computers. Tricks like freeware bundles, fake updates, corrupted pages, malicious third-party ads, unverified download sources, spam email messages, etc. In theory, any of these tactics would work IF you provide something yourself – your carelessness. This is what all parasites need the most. Without it, none of the above-mentioned tactics would do.

So, be more careful. Don’t open emails from unknown senders. The same goes for messages in social media. Stay away from shady pages and illegitimate sites. When you are installing a program/update be more vigilant. Always opt for the Custom settings in the Setup Wizard instead of the Basic ones. This way you will be in complete control of the installation process and you will be able to spot and prevent from entering any additional programs what you don’t want. Don’t forget that negligence leads to infections. Vigilance keeps you safe.
