WebHelper.dll process in the Task Manager warns about adware attack

WebHelper.dll is one of the processes that belong to WebHelper adware that is created for delivering an excessive amount of ads on various websites or even computer’s desktop. Thus, seeing this process running in the Task Manager means that your PC has a potentially unwanted program (PUP) installed.

The WebHelper.dll file is a browser helper object (BHO) that allows the ad-supported application to perform its activities, such as display ads, pop-ups, banners or trigger redirects to sponsored websites.

Additionally, it might help adware to remain on the system and web browser for a long time. Thus, it can protect adware-related browser add-ons from removal as soon as user notices some suspicious activities. Also, this DLL file might also be responsible for helping the PUP to launch its operation on system startup.

However, WebHelper.dll removal is needed in order to stop all bothersome activities on Chrome, Firefox, Explorer or other affected web browser. However, deleting this file itself from one of the subfolders in C:\Windows is not enough.

This adware has other related files that can reinstall WebHelper.dll and continue providing shady commercial content. Therefore, you have to eliminate adware itself in order to stop this process from running in the background.

You can remove adware manually. However, it might be a complicated task. It’s better to remove WebHelper.dll using a reputable anti-malware program. Security software like Reimage can quickly detect and delete the potentially unwanted program from the system.

However, after scanning affected machine with an anti-malware program, you should also reset your web browsers. Adware may have installed cookies or other tracking technologies. Thus, setting the browser to the default state helps to stop developers from spying on your browsing activities.

The DLL appears after installing a potentially unwanted program

WebHelper adware was detected spreading in freeware packages as an optional component. Therefore, it can sneak into the system unnoticed when users install free programs using Quick/Recommended/Standard settings. The problem with them is that they do not openly disclose about third-party components included in the package.

Therefore, to avoid infiltration of PUPs, you have to install new programs using Advanced/Custom settings that allow “unpacking” freeware and seeing what other components are offered to download alongside.

It’s important to unmark all the pre-selected entries because most of the time they are just potentially unwanted applications that do not benefit the user.

The correct way to stop and delete WebHelper.dll

WebHelper.dll removal is definitely needed. However, you have to get rid of the executable together with adware. Adware elimination can be removed either manually or automatically. In order to wipe out PUP without additional software, you have to eliminate all questionable components from Windows OS and web browsers.

However, the easier way to remove WebHelper.dll is scanning the system with anti-malware tool, such as Reimage. Automatic elimination method is especially recommended for those who are dealing with these cyber threats for the first time.
