How to remove ExtraDevice from Mac?

What is ExtraDevice?

ExtraDevice is the name of an application which supposed to improve browsing experience. Although, it displays various intrusive advertisements and promotes the Safe Finder page through akamaihd.net. Quite often software of this type (adware) is designed to gather various information as well. More often than not users download and install adware unintentionally. Therefore, ExtraDevice and other apps of this type are categorized as potentially unwanted applications (PUAs).

ExtraDevice adware

Usually, adware-type applications are designed to display advertisements such as banners, coupons, surveys, pop-ups and/or other types of ads. Those ads not only conceal contents of visited pages but also open untrustworthy pages and/or cause downloads, installations of unwanted apps by executing certain scripts. Therefore, it is not safe to click them. Also, quite quite often apps of this type are designed to gather various information related to user's browsing activities. For instance, 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 such as passwords, phone numbers, credit card details and some other personal data. It is possible that ExtraDevice's developers could sell gathered information to third parties (potentially cyber criminals) who would misuse it to generate revenue in other ways. It means that its users may suffer financial loss, become victims of identity theft, lose access to various accounts, experience problems related to browsing safety, online privacy and/or some other serious issues. For these reasons this app should never be downloaded and installed.

ExtraDevice is similar to more than a few apps, a couple of examples are ConsoleLog, SystemHelper and TaskProduct. What these apps have in common is that they supposed to be useful, include some features, etc. However, they are designed only to generate revenue for their developers by serving ads and gathering information. If there is an app of this type installed on browser and/or computer, then it should be uninstalled from it right away.

How did ExtraDevice install on my computer?

Very often users download and/pr install adware or other PUAs through setups of other software. It is because such apps are often distributed by including them in various download and/or installation setups as additional offers. This distribution method is known as "bundling". As a rule, offers to download and/or install included apps can be declined through setup's settings like "Custom", "Advanced". However, users often do not even check those settings. By leaving them unchanged they allow for included PUAs to be downloaded and/or installed alongside with other, intentionally downloaded and/or installed software. Additionally, unwanted downloads, installations can be caused by clicking deceptive advertisements. However, it can happen only when those ads are designed to 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 like torrent clients, eMule, unofficial websites, freeware download pages, etc.), can be used to distribute unwanted, in some cases malicious apps. Therefore, they should not be trusted. Also, download and installation setups that include settings like "Advanced", "Custom" often contain offers to download and/or install additional, unwanted apps. Those offers should be declined before completing downloads and installations. Furthermore, advertisements that appear on questionable websites can open untrustworthy pages or cause downloads and/or installations of unwanted applications. For these reasons they should not be clicked. Additionally, there should be no suspicious, unwanted plug-ins, add-ons or extensions installed on a browser or 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.
