DeckData adware in detail
Through extensive testing of various applications like DeckData, we have discovered that the ads displayed by them have the potential to promote unreliable websites, scams, questionable applications, and other unsavory content. Furthermore, clicking on these ads can result in the downloading or installation of unwanted applications, particularly if they are designed to execute specific scripts.
Moreover, applications that are similar to DeckData are often designed to take over web browsers (hijack them) by modifying their settings. This includes changing the default search engine, homepage, and new tab page to a fake search engine with a suspicious address.
These fake search engines can promote unreliable websites and show search results generated by untrustworthy search engines. Thus, it is highly advisable not to trust DeckData and similar applications.

More about adware
Adware-type applications have the potential to access a wide range of information, which puts their users at risk of identity theft, compromised personal accounts, and other issues related to online privacy, browsing safety, and more. Some examples of adware applications include AccessUnit, AdjustableBox, and ArchiveOperation.
How did DeckData install on my computer?
It is common for applications similar to BrowserDisplay to be distributed by bundling them with other software. Downloaders and installers that contain adware have "Custom," "Advanced," "Manual," or other settings (or ticked checkboxes). Adware gets installed automatically after the installation process is completed without changing the aforementioned settings.
In some cases, adware can also be installed through deceptive advertisements that are designed to run certain scripts. It can also be distributed using fake installers. Regardless of the method used, most users unknowingly download and install adware.
How to avoid installation of unwanted applications?
It is advisable to download files and applications only from legitimate sources such as official pages and platforms. Do not trust files or apps downloaded using P2P networks, third-party downloaders, or unofficial websites.
When downloading files or apps, be sure to check the downloaders and installers for optional downloads and installations and deselect any unwanted apps before completing the downloads or installations. It is also recommended to avoid clicking on advertisements appearing on dubious pages or notifications displayed by such websites.
If your computer is already infected with DeckData, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
