How to remove KeyData adware and the advertisements it displays?

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

What is KeyData?

KeyData is a rogue app categorized as adware. It also has browser hijacker qualities. Due to the questionable techniques used to distribute software products within these categories, they are also considered to be PUAs (Potentially Unwanted Application).

KeyData adware

KeyData adware in detail

Adware enables the placement of pop-ups, coupons, surveys, banners, and other intrusive adverts - on any visited website and/or different interfaces. The displayed ads seriously diminish the browsing experience and endanger device/user safety.

Intrusive advertisements promote various sale-oriented, untrustworthy, deceptive/scam, and malicious sites. Furthermore, some of these ads can stealthily download/install software (e.g., PUAs) - when clicked on.

Browser hijackers assign fraudulent web searcher addresses as browsers' default search engine, and new tab/window, and homepage URLs. Therefore, new browser tabs/windows opened and search queries typed into the URL bar - redirect to the promoted address.

Fake search engines usually cannot provide search results, so they redirect to Yahoo, Google, Bing, and other genuine ones. Browser hijackers can undo any user-made changes or deny access to the browser settings outright. Hence, restoring a browser is impossible without removing the software hijacking it.

Most PUAs have data tracking abilities. Information of interest includes browsing and search engine histories, IP addresses, personally identifiable details, and so on. The gathered data is then shared with and/or sold to third-parties (potentially, cyber criminals).

In summary, the presence of unwanted apps on devices can lead to system infections, severe privacy issues, financial losses, and identity theft.

Adware in general

FocusDeployBeyondLaunch, and BufferRecord are a few examples of adware. This software looks harmless and offers "useful" features that are rarely operational. This is true of nearly all PUAs. Furthermore, these applications typically have harmful abilities, e.g., running intrusive advertisement campaigns, hijacking browsers, causing redirects, and gathering private data.

How did KeyData install on my computer?

PUAs are distributed using the "bundling" marketing method - packing regular programs with various additions. Rushed download/installation processes increase the risk of unintentionally allowing bundled content into the device. Intrusive adverts proliferate PUAs as well. Once clicked on, the ads can execute scripts to make downloads/installations without user permission. PUAs may also have "official" download sites.

How to avoid installation of potentially unwanted applications?

It is recommended to research software and download it from official/trustworthy sources. Dubious download channels, e.g., unofficial and freeware websites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer bundled/dangerous content.

When downloading/installing, it is recommended to read terms, study possible options, use the "Custom/Advanced" settings, and opt-out from all supplements. Intrusive advertisements appear legitimate, yet they redirect to questionable sites (e.g., gambling, pornography, adult-dating, etc.).

In case of encounters with ads and/or redirects of this type, the system must be inspected and all suspicious applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with KeyData, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
