What is LookupDisplay adware?

LookupDisplay adware is a type of software that displays annoying advertisements and changes the web browser's settings. It may also gather personal information. It is common for applications of this type to be distributed using deceptive methods. LookupDisplay is distributed through a fake Adobe Flash Player installer.

LookupDisplay adware in detail

Usually, applications like LookupDisplay display advertisements (coupons, banners, pop-up ads, surveys, etc.) designed to promote questionable pages. Those ads can be designed to run specific scripts and trigger unwanted download or installation. It is strongly recommended not to trust (click) ads generated by LookupDisplay.

Also, LookupDisplay modifies the web browser's settings such as the address of a default search engine, homepage and new tab. It changes them to an address of a fake search engine. These changes cannot be undone unless LookupDisplay is no longer installed. Apps that promote fake search engines by changing browser's settings are called browser hijackers.

It is important to mention that fake search engines can promote untrustworthy websites (generate misleading results), display unwanted advertisements, or show results generated by other untrustworthy search engines. Therefore, it is recommended to use only legitimate search engines like Google, Yahoo.

Furthermore, it is likely that LookupDisplay collects browsing-related data, for example, Internet Protocol, geolocations, track visited websites, entered search queries. Moreover, it is possible that this application can access credit card details, passwords, telephone numbers, and other personal information.

Individuals behind LookupDisplay might sell collected information to third parties, use it for marketing purposes. If LookupDisplay can read sensitive data, then that data might be misused to steal identities, hijack online accounts, make unauthorized purchases, or monetized in other ways.

Adware in general

Most users install applications like LookupDisplay inadvertently. Therefore, they are called potentially unwanted applications (PUAs). The main purpose of adware is to display advertisements. Adware can also collect information and change web browser's settings. More adware examples are NetFunctionSearch, FlexibleOrigin, and AssistiveMode.

How did LookupDisplay install on my computer?

LookupDisplay is distributed through a fake Adobe Flash Player installer. Usually, fake installers can be downloaded from deceptive websites. It is important to know that those installers can be malicious - they can be designed to install ransomware, Trojans, or other malicious software.

Another popular way to distribute potentially unwanted applications is to bundle them together with other programs. In such cases, downloaders or installers have "Manual", "Custom", "Advanced" or other settings (or ticked checkboxes). Users download or install PUAs together with other programs when they do not change those settings.

It is worthwhile to mention that PUAs are distributed through downloaders and installers for freeware (free software). In some cases, apps of this kind are distributed via advertisements. Users download or install unwanted apps by clicking advertisements designed to execute certain scripts.

How to avoid installation of potentially unwanted applications?

Programs and files should be downloaded from official, trustworthy websites and via direct links. Third-party downloaders, unofficial pages, Peer-to-Peer networks (torrent clients, eMule), and other sources of this kind can be used to distribute PUAs and malicious applications. Third-party installers should never be used as well.

Advertisements appearing on untrustworthy websites can open other pages of this kind or download, install unwanted software. Those ads should not be clicked. Downloaders and installers with settings like "Advanced" and "Custom" should be examined - they may be used to distribute PUAs.

Unwanted, suspicious extensions, plug-ins, or add-ons installed on a browser and programs of this kind installed on the operating system should be removed. If your computer is already infected with LookupDisplay, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
