How to remove AccessibleDataLookup from Mac?

What is AccessibleDataLookup?

AccessibleDataLookup serves advertisements and changes certain browser settings to promote a fake search engine (its address). Also, it could be capable of accessing (collecting) certain information. Simply said, AccessibleDataLookup functions as adware and a browser hijacker. In most cases users download and install apps of this type unknowingly, for this reason they are categorized as potentially unwanted applications (PUAs). AccessibleDataLookup is distributed through a deceptive installer, supposedly an installer for the Adobe Flash Player.

AccessibleDataLookup adware

Typically, apps like AccessibleDataLookup serve coupons, banners, surveys, pop-ups and/or other types of advertisements. It is common that when users click those ads they end up on questionable websites or allow them execute certain scripts that cause download and/or installation of some PUA. Furthermore, AccessibleDataLookup is designed to promote a fake search engine. Such search engines are promoted by assigning a certain address as the address of a homepage, default search engine and new tab so that users would be forced to visit it every time they open a browser, enter search queries into URL bar, or open a new browser tab. Fake search engines do not generate unique results (they provide results generated by some other, legitimate search engine), also, they can generate results that would include links to untrustworthy websites. It is worthwhile to mention that users can remove address of a fake search engine from browser settings only when a browser hijacker (in this case AccessibleDataLookup) is no longer installed. One more issue with apps like AccessibleDataLookup is that they can be designed to collect data like IP addresses, geolocations, addresses of visited pages, entered search queries, etc., or even sensitive information. Moreover, their developers could misuse collected details to generate revenue. For instance, they could sell it to third parties (potentially cyber criminals). Users who have apps like AccessibleDataLookup installed on a browser and/or operating system are at potential risk of becoming victims of identity theft, experiencing problems related to online privacy, browsing safety, or other issues. Therefore, apps of this type should never be downloaded and installed.

To summarize, applications like AccessibleDataLookup are designed to generate revenue for their developers by serving ads, promoting fake search engines and/or gathering various information. They are not only useless for their users but also can cause them various problems. If an app of this type is already installed on a browser and/or computer, then it should be uninstalled as soon as possible. A couple of examples of other apps of this type are NetModuleSearch, WebFunctionSearch and AssistiveDisplaySearch.

How did AccessibleDataLookup install on my computer?

As mentioned in the introduction, AccessibleDataLookup is distributed through a fake installer for Adobe Flash Player. Third party, fake installers like this one should never be used - it is common that they are designed to distribute (install) malware, for example, Trojans, ransomware. Also, it is common that users download and/or install PUAs through deceptive advertisements that are designed to execute certain scripts or together with other programs (when PUAs are included in their download and/or installation setups). The second distribution method is called "bundling". Typically, offers to download and/or install included apps can be declined in "Custom", "Advanced" and other settings of setups. When users download and/or install programs without checking (and changing) those settings, they allow for included apps to be downloaded and/or installed too.

How to avoid installation of potentially unwanted applications?

Programs and files should not be downloaded through unofficial pages, third party downloaders, Peer-to-Peer networks (e.g., torrent clients, eMule), and other sources of this kind, or installed via third party, unofficial installers. They should be downloaded only from official pages and via direct download links. Downloads and installations should not be completed without checking "Advanced", "Custom" and other settings and declining offers to download and/or install additionally included, unwanted software. Ads that appear on shady pages should not be clicked as well, they may be designed to cause downloads, installations of unwanted applications, or simply open other, potentially malicious sites. If there are any unknown, unwanted, suspicious extensions, plug-ins or add-ons installed on a browser (or programs of this kind installed on the operating system), then they should be uninstalled. If your computer is already infected with AccessibleDataLookup, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
