How to uninstall ExtraDevice adware

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

What is ExtraDevice?

The ExtraDevice application is supposedly designed to improve the browsing experience. In fact, it displays various intrusive advertisements and promotes the Safe Finder web page through akamaihd.net. This type of adware can also record information. Generally, users download and install adware unintentionally.

Therefore, ExtraDevice and other apps of this type are categorized as potentially unwanted applications (PUAs).

ExtraDevice adware

Adware-type applications display advertisements such as banners, coupons, surveys, pop-ups and others. They conceal underlying content of visited web pages, open untrusted web pages, and cause download/installation of unwanted apps by executing certain scripts.

Therefore, it is not safe to click these ads. PUAs record information relating to users' browsing activities including addresses of visited pages, entered search queries, IP addresses, geolocations, and other browsing-related information.

Research shows that ExtraDevice can read sensitive information from websites, including passwords, telephone numbers, credit card details and other personal data. ExtraDevice's developers might sell the information to third parties (potentially, cyber criminals) who then misuse it to generate revenue in other ways.

People could then suffer financial loss, become victims of identity theft, lose access to various accounts, and experience problems relating to browsing safety, online privacy and other serious issues. For these reasons, never download or install this app.

ExtraDevice is similar to many other rogue apps such as ConsoleLog, SystemHelper and TaskProduct. They are supposedly be useful and include various features, however, they are designed only to generate revenue for the developers by serving ads and gathering information.

Remove all PUAs from browsers and operating systems immediately.

How did ExtraDevice install on my computer?

Users often download and install adware or other PUAs inadvertently through the set-ups of other software. These rogue apps are often distributed by including them into download/installation set-ups as 'additional offers'. This distribution method is known as "bundling".

Generally, offers to download and install are included in settings such as "Custom" and "Advanced", however, many users often fail to check and change these settings. By leaving them unchanged, they allow PUAs to be downloaded and installed together with their required software.

Additionally, unwanted downloads and installations can be caused by clicking deceptive advertisements, which then execute certain scripts.

How to avoid installation of potentially unwanted applications

All programs and files should be downloaded from official pages and through direct links. Other channels (such as third party downloaders, installers, Peer-to-Peer networks such as torrent clients, eMule, unofficial websites, freeware download pages, etc.), can be used to distribute unwanted, malicious apps.

Therefore, they should never be trusted. Check all installation settings such as "Advanced" and "Custom" and decline offers to download or install additional, unwanted apps before completing the process. Furthermore, advertisements that appear on dubious websites can open untrusted pages or cause download/installation of unwanted applications.

For these reasons, never click intrusive, unwanted ads on these rogue sites.

Remove any suspicious, unwanted plug-ins, add-ons and extensions installed on the browser, and software of this kind that is installed on the operating system. If your computer is already infected with ExtraDevice, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
