How to remove LookupShare from Mac computers

What is LookupShare?

LookupShare is advertised as an app that helps users to browse the web, however, it is categorized as a potentially unwanted application (PUA) and adware. Typically, people download and install software such as LookupShare unintentionally. When installed, adware-type apps serve advertisements and gather information relating to users' browsing activities. We advise you to uninstall LookupShare and other apps of this type installed on the browser and/or operating system immediately.

LookupShare adware

Adware-type apps such as LookupShare display intrusive advertisements and other unwanted content such as surveys, pop-up ads, coupons, banners, and so on. People who click these ads are usually redirected to untrustworthy websites, which are used to promote dubious software. Furthermore, the ads might run scripts that download and install other PUAs. LookupShare can read sensitive information from websites, including saved passwords, telephone numbers, credit card details, and so on. PUAs also collect browsing-related data including, for example, IP (Internet Protocol) addresses, addresses of visited websites, entered search queries, geolocations, etc. Adware developers share the details with third parties (cyber criminals) who misuse them to generate revenue. Therefore, never install adware. If LookupShare or other adware is installed on the browser or computer, remove it immediately.

There are many adware-type apps online. Some examples are SmarterHD, DefaultProducts, and PremiumForward. These apps may seem useful, however, developers advertise simply them as legitimate and useful. In most cases, they are useless and designed only to generate revenue for the developers.

How did LookupShare install on my computer?

Apps such as LookupShare can be downloaded from their 'official' download pages, however, most people download and/or install them inadvertently via clicked intrusive (deceptive) ads and when software developers distribute PUAs using a deceptive marketing method called "bundling". They include PUAs in download/installation set-ups of regular software and hide related information in "Custom", "Advanced", and other similar settings. Download/installation of PUAs usually happens when people fail to check the settings and leave them unchanged.

How to avoid installation of potentially unwanted applications

Study each download/installation setup and check all settings such as "Custom" or "Advanced", etc. that are included. Dismiss any offers to download or install additional software. Download software only from official websites and using direct download links. Tools or sources such as third party downloaders, installers, Peer-to-Peer networks, unofficial websites, etc., are often used to promote unwanted apps. Therefore, these sources/tools should not be used to download or install software. Many intrusive advertisements redirect to untrustworthy websites, especially when displayed on dubious web pages. They can also lead to unwanted downloads and installations. Do not trust or click these ads. Remove all unwanted, unknown apps (extensions, add-ons, plug-ins) that are installed on the browser, or programs of this kind 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.
