How to stop redirects to lkysearchex on Mac computers

What is lkysearchex?

lkysearchex is an untrustworthy website that people do not often visit intentionally. If a browser opens lkysearchex automatically, an adware-type app is likely to be installed on the browser or operating system. As well as opening dubious web pages, adware displays intrusive advertisements and/or collects details relating to users. Apps of this type are categorized as potentially unwanted applications (PUAs), since people usually download and install them unintentionally.

redirects to lkysearchex on a Mac computer

Sites such as lkysearchex are opened by adware-type apps (e.g., WindowMixAssistEngineResultsValue, and so on) installed ion the system. When installed, adware displays unwanted, intrusive, and often deceptive ads. Examples include coupons, banners, surveys, pop-ups, etc. Generally, people who click these ads are redirected to untrustworthy websites, some of which might be malicious. Furthermore, the ads might be designed to run scripts that cause unwanted downloads and installations. Installed aware can also collect details such as users' IP addresses, geolocations, entered search queries, URLs of visited websites, and other, potentially sensitive information. Adware developers often share the information with third parties (potentially, cyber criminals) who misuse it to generate revenue.

Having PUAs installed can lead to problems relating to browsing safety, privacy, or even identity theft. If clicked, ads might cause unwanted downloads or installations. Typically, PUAs help developers to generate revenue and provide no real value. We strongly recommend that you uninstall all adware-type or other potentially unwanted apps immediately.

How did adware install on my computer?

Most people download and install PUAs such as adware unintentionally. These apps can be downloaded/installed through clicked intrusive, deceptive advertisements. In some cases, if clicked, these ads run scripts that cause unwanted downloads/installations, however, PUAs are also downloaded/installed through the set-ups of other (usually free) software. This happens when developers use a deceptive marketing method called "bundling" - they include PUAs in download/installation set-ups and related hide information in "Custom", "Advanced", and other settings. When people leave available settings unchecked and unchanged, they often allow various PUAs to be downloaded and installed with regular software.

How to avoid installation of potentially unwanted applications

Avoid downloading or installing programs through third party software downloaders/installers, Peer-to-Peer networks such as torrent clients, eMule, unofficial pages, and other similar sources. The safest way to download is from official websites and via direct links. Do not finish any download or installation process without checking "Custom", "Advanced" and other settings, and dismissing offers to download or install potentially unwanted apps. Avoid clicking intrusive ads, especially if they are displayed on dubious websites relating to gambling, pornography, adult dating, and so on. They can be designed to cause unwanted downloads/installations or open potentially malicious websites. To stop your browser from opening dubious web pages or showing ads, uninstall all unwanted extensions, plug-ins, and add-ons that are installed on it. Also remove any software of this type installed on the operating system. If your computer is already infected with browser hijackers, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
