Remove CoverOpen adware

What is CoverOpen?

CoverOpen is a program that supposedly helps people to browse the internet efficiently (providing fast searches, accurate results, and enhancing the browsing experience in other ways). In fact, this app is categorized as adware, software that displays unwanted, often deceptive ads.

People usually download and install apps of this type inadvertently, and thus they are categorized as potentially unwanted applications (PUAs). Additionally, these apps can operate as information tracking tools, collecting various user details.

When CoverOpen is already installed, it displays intrusive ads including, for example, coupons, banners, surveys, pop-up ads, and so on. It is not safe to click these, since ads displayed by adware-type software commonly lead to untrustworthy websites or start download/installation of unwanted applications.

Furthermore, the apps might also record browsing-related information. Examples of details that such PUAs usually collect are IP addresses, geolocations, addresses of visited websites, entered search queries, and so on. Developers share the data with third parties (potentially, cyber criminals) who misuse private information to generate revenue.

In summary, people who have adware installed on their computers and/or browsers risk experiencing unwanted downloads and installations, problems with privacy, browsing safety, or even becoming victims of identity theft. For these reasons, we recommend that you uninstall all adware immediately.

CoverOpen is almost identical to many other adware-type apps including WindowGroup, OnlyApplication, and ExtraWindow. All feed users with unwanted advertisements and, in many cases, gather information. In any case, having adware installed usually leads to problems - never trust apps of this type or have them downloaded or installed on your system.

How did CoverOpen install on my computer?

People often download and/or install PUAs through intrusive advertisements that they have clicked, or they are tricked by developers who use a deceptive marketing method called "bundling". They use this method to trick people into downloading and/or installing unwanted programs together with other, regular software.

They include PUAs into the set-ups of various software (typically, these programs are free) and do not disclose relevant information. They hide the information in "Custom", "Advanced", "Manual" and other parts of the set-ups. Note, however, that developers can only succeed when people download/install programs and fail to check and change the settings.

How to avoid installation of potentially unwanted applications

Do not download or install any software via third party software downloaders/installers, Peer-to-Peer networks (eMule, torrent clients), dubious pages, etc. Use only official and trustworthy websites. Opt-out of offers to download or install unwanted apps before completing any setup.

Typically, these offers can be found in "Custom" and "Advanced" settings of the download/installation set-ups. Do not click intrusive ads, even if they seem legitimate. They often cause redirects to potentially malicious websites or download/install unwanted apps.

To stop your browser from causing unwanted redirects or showing ads, uninstall all unwanted, suspicious extensions, plug-ins, and add-ons from the browser, and programs from the computer. If your computer is already infected with CoverOpen, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
