Uninstall GenerelOpen from Mac computers

Also Known As: Ads by GenerelOpen
Type: Mac Virus
Damage level: Medium

What is GenerelOpen?

The GenerelOpen app supposedly allows people to search more efficiently, however, research shows that it operates as an adware-type app. Adware is software that feeds users with intrusive advertisements. These apps sometimes also collect information relating to users' browsing habits.

In most cases, people download and install adware unintentionally, and for this reason, GenerelOpen is also known as a potentially unwanted application (PUA).

GenerelOpen adware

After installation, adware starts to display unwanted, intrusive ads such as coupons, banners, surveys, pop-ups, and others that conceal underlying content of visited websites. When clicked, these ads can open untrustworthy or even malicious websites. For example, those used to advertise various PUAs such as browser hijackers and other apps that might cause problems.

Additionally, some ads displayed by adware run scripts that download and even install unwanted software. Note, however, that they cannot perform these actions unless they are clicked. Furthermore, GenerelOpen might also gather data such as IP addresses, entered search queries, addresses of opened/visited sites, geolocations, and so on.

Developers send the information to other people who often misuse it to generate revenue. These third parties might include cyber criminals. By sharing the details, developers put users at risk of problems with privacy, browsing safety, and even identity theft.

GenerelOpen is virtually identical to other apps such as StudyDisplay, MatchKnowledge, and Top Results. People often download and install these apps when they are advertised as legitimate, useful, and so on. Unfortunately, PUAs (including adware) do not operate as advertised and are designed only to generate revenue for their developers.

How did GenerelOpen install on my computer?

Most PUAs infiltrate systems without users' knowledge - people download and install them unintentionally. In most cases, this happens when they click intrusive advertisements or download and install software without checking settings such as "Custom" and "Advanced" available in the set-ups.

These settings include information about additionally-included apps that are installed/downloaded with regular software if the settings remain unchanged. The inclusion of PUAs into the set-ups of other software is known as "bundling". Developers use this deceptive marketing method to trick people into unintentional downloads and installations.

How to avoid installation of potentially unwanted applications?

Download software from trustworthy, official pages and use direct download links. Do not use third party software downloaders, installers, Peer-to-Peer networks such as torrent clients, eMule, unofficial pages, and so on. Check "Advanced", "Custom", and other settings that are included in any download or installation setup - they often contain information about potentially unwanted downloads/installations of other programs.

These offers should be dismissed before completing set-ups. Advertisements that are displayed on unofficial, dubious websites should not be clicked. They can lead to dubious websites or might even cause unwanted downloads/installations. To prevent the browser from displaying ads or opening dubious pages, uninstall all unwanted extensions, plug-ins, and add-ons.

The same applies to software of this type installed on the operating system. If your computer is already infected with GenerelOpen, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
