What kind of application is ExtendedSample?
While testing ExtendedSample, our team learned that this application displays intrusive advertisements. Thus, we classified ExtendedSample as adware (advertising-supported software). We discovered this app after executing a fake installer masquerading as the installer for Adobe Flash Player.
More about ExtendedSample adware
ExtendedSample shows unwanted advertisements (e.g., banners, pop-up ads, surveys, coupons) that can open shady websites. Those ads can lead users to phishing websites and technical support scam sites urging visitors to call fake numbers or perform other actions. Also, clicking those ads can open malicious pages and websites offering to download untrustworthy apps.
It is common for apps like ExtendedSample to have information-tracking abilities. In such cases, they can access browsing-related information and even sensitive data such as passwords, credit card details, phone numbers, etc. Data collected by untrustworthy apps can be misused for malicious purposes (e.g., to steal identities and hijack online accounts).

Adware in general
The purpose of adware is to bombard users with annoying ads designed to promote mostly shady apps and pages. Additionally, adware can be capable of hijacking a web browser (manipulating its settings) and gathering data. Most advertising-supported apps are promoted as legitimate and useful. However, it is rarely mentioned what their downsides are.
More adware examples are RealInfo, MainFrameSelect, and LegendDeploy.
How did ExtendedSample install on my computer?
ExtendedSample installs via fake installer promoted on deceptive websites suggesting that the installer version of Adobe Flash Player is outdated. Also, adware is distributed via installers for other software and untrustworthy advertisements designed to execute certain scripts.
When adware is bundled with other software (included in installers), users install it when they finish installations without deselecting optional installations. Usually, it can be done using "Advanced", "Custom", "Manual", or similar settings provided in installers.
How to avoid installation of unwanted applications?
Download applications from official websites and stores. Do not trust apps and files downloaded from shady websites or via P2P networks, third-party downloaders, and similar sources. Deselect unwanted apps bundled with desired software before finishing downloads and installations.
Also, do not trust ads on shady pages or allow such sites to show notifications. If your computer is already infected with ExtendedSample, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
