How to remove the AnalyserKey adware?

Also Known As: Ads by AnalyserKey
Type: Mac Virus
Damage level: Medium

What is AnalyserKey adware?

AnalyserKey is advertising-supported software - it generates advertisements. It also has the qualities of a browser hijacker - it changes a web browser's settings to promote a fake search engine. It is likely that AnalyserKey collects various information as well. Typically, users install adware-type apps unintentionally because they are distributed using questionable methods.

AnalyserKey adware in detail

Pretty often, advertisements generated by applications like AnalyserKey are used to promote questionable websites, for example, download websites for potentially unwanted applications, pages designed to extract personal information. Also, those advertisements can be designed to cause unexpected downloads or installations.

A couple of examples of websites that ads generated by an application like AnalyserKey could open are "MALWARE DETECTED Action Required", "Receive iPhone 12", and "Apple Platform Security". In one way or another, those advertisements should not be clicked. Typically, apps like AnalyserKey generate banners, coupons, pop-ups, surveys.

Furthermore, this application changes web browser's settings such as the address of a default search engine, homepage and new tab to an address of a fake search engine - it hijacks a browser. The problem with fake search engines is that they could generate misleading results (show links to potentially malicious pages in their results).

Typically, users cannot remove a fake search engine (its address) from settings unless they uninstall a browser hijacker. Another reason not to keep an app like AnalyserKey installed is that it may be designed to collect various information (IP addresses, entered search queries, visited websites, and so on).

In some cases, adware-type apps (similar to AnalyserKey) can access sensitive information such as passwords, credit card details, telephone numbers. Information collected by apps of this type could be misused in various ways, for example, to steal identities, personal accounts, make unauthorized purchases.

AnalyserKey adware in general

AnalyserKey is not a trustworthy (or useful) application. The main purpose of this app is to generate advertisements and hijack a browser. There are plenty of apps like AnalyserKey on the Internet. Some examples are OnlineExplorer, DataBoost, and InetImprovment. As a rule, users install them inadvertently.

How did AnalyserKey adware install on my computer?

It is common that users cause unwanted downloads and installations through downloaders and installers for other programs - when PAUs are included in them as optional offers. In most cases, offers to download or install PUAs are mentioned and can be deselected in "Advanced", "Custom" or other settings, or by unticking ticked checkboxes.

Users agree to download or install additional apps when they leave the aforementioned settings unchanged. Sometimes, users cause unexpected downloads or installations by clicking advertisements designed to execute certain scripts. It is worth mentioning that apps of this kind appear mostly on untrustworthy pages.

How to avoid installation of potentially unwanted applications?

It is recommended to download programs from official web pages and via direct download links. Tools, sources like third-party downloaders (and installers), torrent clients, eMule (or other Peer-to-Peer networks), unofficial pages could be used to distribute potentially unwanted, or even malicious applications.

Also, it is advisable to check "Advanced", "Custom" and other similar settings of any downloader or installer and see if those settings mention unwanted offers. Such offers should be declined before finishing downloads and installations. Additionally, it is recommended not to trust advertisements on shady pages.

Those ads could cause downloads, installations of unwanted applications or open various unreliable pages. Unknown, unwanted, or suspicious extensions, plug-ins, or add-ons installed on a browser or programs of this kind installed on the operating system should be removed. If your computer is already infected with AnalyserKey, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
