How to remove LookupShare from Mac?

What is LookupShare?

LookupShare is advertised as an app that helps users to browse the web. However, LookupShare is categorized as a potentially unwanted application (PUA) and adware. Typically, people download and install software like LookupShare unintentionally, when installed, adware-type apps serve various advertisements and gather information related to user's browsing activities. We advise to uninstall LookupShare (or any other app of this type that is installed on a browser or/and operating system) as soon as possible.

LookupShare adware

Adware-type apps like LookupShare are designed to display intrusive advertisements and other unwanted content such as surveys, pop-up ads, coupons, banners, and so on. People who click such ads usually get redirected to various untrustworthy websites. Quite often opened pages are used to promote questionable software. Also, those ads might be designed to run scripts that download and install other PUAs. Furthermore, LookupShare can read sensitive information from websites, including saved passwords, phone numbers, credit card details, and so on. Very often apps of this type collect browsing-related data as well, for example, IP (Internet Protocol) addresses, addresses of visited websites, entered search queries, geolocations, and other data of this type. Adware developers usually share recorded details with third parties who misuse them to generate revenue, or/and they misuse that data by themselves. It is worth mentioning that they might share it with cyber criminals. These are the main reasons why adware should not be installed. If LookupShare or other adware is installed on a browser or computer, it should be removed immediately.

There is a great number of adware-type apps, a couple more examples are SmarterHD, DefaultProducts and PremiumForward. Typically, these apps supposed to be somehow useful, however, their developers only advertise them as legitimate and useful. In most cases these apps are worthless for their users and are designed only to help generate revenue for their developers.

How did LookupShare install on my computer?

It is possible that apps like LookupShare can be downloaded from their download pages. However, most people download and/or install them unwillingly, inadvertently. Typically, they get downloaded or/and installed via clicked intrusive (deceptive) ads and when software developers distribute PUAs using a deceptive marketing method called "bundling". They distribute them by including them in download or installation setups of various programs and hiding information related to it in their "Custom", "Advanced" and other similar settings. Downloads and installations of various PUAs usually happen when people leave those settings unchanged, in other words, when they download or/and install software without checking them.

How to avoid installation of potentially unwanted applications?

We advise to always analyze every download or installation setup and check all settings like "Custom" or "Advanced" that are included in it. If those settings contain offers to download or install additional software, then they should be dismissed. Also, we strongly recommend to download software only from official websites and using direct download links. Tools or sources like third party downloaders, installers, Peer-to-Peer networks, unofficial websites, etc., are often used to promote unwanted apps. Therefore, such sources/tools should not be used to download or install any software. Furthermore, most intrusive advertisements (especially when displayed on questionable pages) redirect people to untrustworthy websites. Sometimes they can lead to unwanted downloads or even installations. We advise against trusting and clicking such ads. Also, we recommend to remove all unwanted, unknown apps (extensions, add-ons or plug-ins) that are installed on a browser or programs of this kind that are installed on the operating system. If your computer is already infected with LookupShare, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
