AboutExtended adware in detail

AboutExtended delivers banners, pop-ups, coupons, or other ads. Those ads could open download pages for PUAs, various scam pages used to trick visitors into providing personal information, purchasing questionable software or services, or other potentially malicious sites.

AboutExtended hijacks a web browser by changing the homepage, default search engine, and new tab URL to a fake search engine (its address). Fake search engines can be used to promote untrustworthy websites. They can include links to shady pages in their results or show results generated by other unreliable search engines.

More information about AboutExtended

Also, AboutExtended could be designed to collect browsing data (like visited pages, IP addresses), or even sensitive information (like passwords, credit card details). Thus, this app should not be trusted and eliminated from affected systems and browsers as soon as possible. More adware examples are OptimizationLaunch, GeneralAnalog, and SampleCheck.

How did AboutExtended install on my computer?

Adware and other PUAs are distributed through fake installers, advertisements, downloaders, and installers for other programs. Fake installers are promoted on deceptive websites (for example, on pages suggesting that a computer is infected, some software needs to be updated).

Ads can cause unwanted downloads or installations when they are designed to run specific scripts and users click those ads. PUAs get downloaded or installed through downloaders or installers for other programs when users do not decline optional downloads, installations in "Custom", "Manual", "Advanced", or similar settings.

How to avoid installation of potentially unwanted applications?

Downloads from unreliable sources can be used to distribute potentially unwanted or malicious apps. Thus, files and apps should be downloaded from legitimate, official pages. Downloaders and installers with "Custom", "Advanced", or other settings should be checked for optional downloads or installations.

It is also recommended not to click on pop-ups, advertisements, notifications displayed by questionable websites. If your computer is already infected with AboutExtended, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
