Written by Tomas Meskauskas on
What kind of application is ExtendedApp?
Our examination of ExtendedApp has shown that it operates as adware. It can display intrusive and often deceptive advertisements. Additionally, several security vendors have flagged the app as malicious. Users should not install ExtendedApp and should remove it if it is already present.
ExtendedApp adware in detail
ExtendedApp shows various types of advertisements, including pop-ups, coupons, and banners. These ads can contain fake offers, warnings, and alerts to deceive users into interacting with them. If clicked, ExtendedApp's ads may expose users to scams, unwanted downloads, and other online threats.
Users may land on sites hosting fake lotteries, giveaways, technical support scams, phishing pages, and other unreliable web pages. These sites can be used to steal personal information (e.g., login credentials, credit card details, or ID card information) or money. They can also be utilized to deploy malware or other unwanted software.
Besides displaying unwanted ads, ExtendedApp may collect data, such as IP addresses, location information, browsing history, and similar information. Sometimes, such apps are capable of accessing personal details like login credentials and email addresses. This data could be exploited for malicious activities or sold to third parties.
Additionally, ExtendedApp can cause system performance issues by slowing down computers. Due to these risks, it is recommended to uninstall ExtendedApp if it is found on your system. It is important to note that manually removing the app can be challenging. In such cases, we recommend using tools like Combo Cleaner for a thorough removal.

How did ExtendedApp install on my computer?
Adware is often bundled with other (e.g., free or untrustworthy) software. Users who bypass installation steps and fail to modify default settings (like "Advanced" or "Custom" options) may unknowingly install it. This bundling technique is a common method used to distribute adware and other questionable programs.
Adware can also spread through other channels, including fake software updates, misleading notifications, untrustworthy websites, unofficial app stores, peer-to-peer (P2P) networks, third-party downloaders, and deceptive ads. It is often unintentionally downloaded and installed by users.
How to avoid installation of unwanted applications?
Always obtain apps and files from reliable sources, like official websites or well-known app stores. When installing, opt for "Advanced" or "Custom" settings and uncheck any boxes to avoid installing unwanted programs. Avoid engaging with suspicious ads, pop-ups, or links on unreliable websites and reject requests to show notifications from questionable sites.
Ensure your system and software are up to date, and regularly scan your device with a trusted security tool. If your computer is already infected with ExtendedApp, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
