Click PDF Search

Click PDF Search

There’s no need to be constantly disturbed by Click PDF Search ads, page redirects, new tabs, and banners every time you open your web browser. If a browser hijacker called Click PDF Search has recently put you in that situation, on this page, you’ll learn how to save yourself from the invasion.

Click PDF Search will display pop up messages and redirect your searches

In the next lines, we’ve prepared a detailed removal guide with screenshots, and explanations on how to find and remove the ad-generating files. But we highly recommend that you read the information that follows before you do so. Not only will it give you a better understanding of exactly what browser hijackers can do, but also it will offer you a few tips on how to keep them away.

What is Click PDF Search capable of?

Click PDF Search may affect all browsers (Chrome, Firefox, Edge, etc.), and change the homepage, place another search engine, or install a page-redirect service, which constantly redirects your searches to some unknown web sites full of ads, banners, and pop-up boxes. The program could also trigger some browsing-related disturbance such as screen-freezing, and lags, and  thus discourage people from surfing the internet through that browser. Click PDF Search may even collect, and transmit data about the activity of the user back to its developers. Usually, this is done with the goal of optimizing the ads displayed according to the searches of the user, and increasing the chances of more people clicking on those ads. However, some users may consider this data collection as an invasion of their privacy, particularly when it is not really clear where this information is going, and how it is stored.

Is Click PDF Search a  virus?

If you’re wondering why the advertisements are so irritating, you should understand they’re just put on your screen to gain revenue. Fortunately, this is not an illegal criminal scheme for quick cash. It is not the same as a Ransomware that blackmails you, or a Trojan that may try to drain your banking accounts. Instead, this revenue-earning method enables the developers of browser hijackers to gain some income from every click the displayed advertisements receive. That’s why they’ve programmed Click PDF Search to show as many of them as possible on your screen, and to even automatically redirect people to some pre-defined websites. ⠀

Users who haven’t experienced this kind of activity before usually think they have been infected by a virus, but that’s not the case. It’s important to note that browser hijackers like Wave browser, Humisnee aren’t malicious programs–they don’t have damaging code in them, that can harm your system, nor can they replicate themselves and automatically get to other computers in the same network. And although they might really irritate you with their annoying advertisements, such programs certainly can’t encrypt your files as Ransomware infections can, so if you detect them on your PC, you don’t really need to get panicked. However, you always have the option to uninstall them if you don’t want to tolerate the irritating ad-generating activity.

How to uninstall Click PDF Search successfully?

Uninstalling a browser hijacker may be a bit of a tricky task. Yet, we are sure that with the help of the removal guide below, you will be able to remove the unwanted components once and for all. Investing in proper system protection with good anti-malware software is also a good idea, as this will make sure you don’t meet any such annoying programs in the future.
