Popunderclick virus Removal Guide

What is Popunderclick virus?

Where do Popunderclick ads come from?

The appearance of Popunderclick ads can be a painful experience because each of your search sessions is filled with commercial notifications that are seeking to redirect you to sponsored websites. Besides, adware-type application (extension, add-on, toolbar, etc.) which is hiding behind these ads can also track your online activities for getting more knowledge about ads that attract you. Unfortunately, but there is no guarantee that this non-personal information, which is usually collected by Popunderclick virus, won’t be shared with third parties. Typically, it is used for building specific networks for marketing campaigns and similar aims, so be careful with programs that are capable of tracking you! It seems that the most affected web browser is Google Chrome, so it might take some patience to get rid of the adware from this browser. To block user from eliminating it by resetting the affected web browser, this adware spreads together with browser helper objects (BHOs) and similar components. They can be used for reinstalling this malware and launching it during the next browsing session, so you need to use automatic removal for Popunderclick.com removal.

The most important thing that should encourage you to take care of it is that it is created with a sole intention of advertising third-party content via sponsored ads and links which may suddenly appear on the browser underlying your visited websites and pages. It is natural that creators need to promote their products and are looking for the most effective techniques to do it, unfortunately, Popunderclick.com is not the most conscientious advertiser to choose for this purpose. This program chooses shady techniques to get into the computers, employ intrusive strategies to advertise the predetermined content and may as well have some questionable parties in its circle of affiliates. Thus, we warn you to be careful about using this risky program and evaluate whether you really want to sacrifice your peaceful browsing for a couple of most likely worthless online offers. Do not hesitate to remove Popunderclick from your computer if you did not install it in the first place. It only takes up your computer’s space, after all. We suggest eliminating the infection using trustworthy antivirus software, for instance FortectIntego.

An illustration of the Popunderclick ads

Wondering how can you recognize if your computer has been affected with this adware? Luckily, Popunderclick hijack is quite obvious. Apart from the suspicious, unfamiliar processes that you might notice running in your task manager, you will see banners, pop-up ads, video advertisements and similar content all over your visited websites. This content might be marked by particular slogans such as “Ads by” or “Powered by” which will help you identify the infection. The unexpected appearance of the additional content such as new toolbars, add-ons, extensions on your browser might also be linked to this adware. As we have already mentioned, this program uses browser helper objects to spy on its users and shares this information with its developers to make its sponsored ads more effective. This way, adware creators learn more about the market demand and concrete interests of a specific user and can generate more appealing ads based on this. It also suggests that keeping this program installed on the computer is highly unadvisable because the potential privacy violations are just around the corner. It is better to take care of the Popunderclick removal before more of your information becomes exposed to the greedy advertisers.

Do you know how to prevent adware infection?

Most adware infections occur when the users are poorly informed about the ways malicious software creators use to distribute their products. Popunderclick as well as thousands of similar programs are often pinned to the software bundles and stealthily install on the computers. Thus, rushing through the installation process may cost you the freedom of choosing what software you really want to allow on your PC. Also remember that “Quick” or “Recommended” settings do not give you the opportunity to inspect the software bundles and allow all the included software to install in one go. We highly advise sparing some time to install software via “Advanced” or “Custom” modes which guide you through all of the installation steps and give you the opportunity to opt-out undesirable content.

How to remove Popunderclick?

Adware which hides behind Popunderclick problem is a potentially unwanted program. However, those who have already been affected by it will agree that it is a nasty infection that uses various techniques for preventing its removal. However, don’t even think that you can’t beat it!

How to prevent from getting adware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
