How to remove GroupSource from Mac computers

What is GroupSource?

Like most adware-type applications, GroupSource is designed to feed users with advertisements and collect information. Additionally, it designed to promote the Safe Finder website by opening it via the akamaihd.net web address. People often download and install adware unintentionally and, therefore, apps like GroupSource are categorized as potentially unwanted applications (PUAs).

GroupSource adware

Adware serves pop-ups, coupons, banners surveys and other similar advertisements. Commonly, these promote dubious websites and/or unwanted applications. Therefore, people who click these ads allow them to open dubious sites or execute scripts designed to download and install unwanted, potentially malicious apps. Therefore, ads that appear due to GroupSource being installed on browsers and computers can cause serious problems if clicked. Furthermore, adware often gathers information relating to users' browsing activities. For example, IP addresses, geolocations, URLs of visited pages, entered search queries and other browsing data. Some PUAs can record private, sensitive details. Research shows that GroupSource can read/access data such as passwords, credit card details, telephone numbers and other sensitive, personal information. These details can be misused to steal identities, various accounts, make fraudulent purchases and transactions, etc. The data might also be sold to third parties, potentially cyber criminals. In summary, users of GroupSource might become victims of identity theft, experience problems with online privacy, suffer monetary loss, and other problems. Therefore, never download or install this, or other similar apps.

Some more examples of apps similar to GroupSource are PlusSpecial, EngineOrder and InteractiveSpeed. Developers often advertise them as supposedly improving the browsing experience or delivering various features, however, most are useless and can cause serious issues. Therefore, remove GroupSource and other PUAs from the browser and operating system immediately.

How did GroupSource install on my computer?

In most cases, PUAs (including adware such as GroupSource) are downloaded and installed through deceptive advertisements that users click, or when developers distribute them using a deceptive marketing method called "bundling". This latter method is used to trick people into downloading and installing PUAs together with other programs by including them into the software set-ups as 'additional offers'. Included apps are usually listed in "Advanced", "Custom and other similar settings of the set-ups. Many people leave these settings unchecked and unchanged, thereby granting permission for PUAs to be downloaded and installed with regular programs. Deceptive advertisements can cause unwanted downloads and installations when they execute certain scripts, however, this happens only if they are clicked.

How to avoid installation of potentially unwanted applications

Third party downloaders, installers, unofficial websites, Peer-to-Peer networks such as torrent clients, eMule, and other similar channels are used to distribute adware and other PUAs. They also proliferate malicious programs. Therefore, never use these channels to download or install software. All files and programs should be downloaded from official websites and via direct links. Check all "Custom", "Advanced", "Manual" and other settings of the set-ups and decline offers to download or install unwanted applications. Do not click intrusive advertisements that appear on dubious, unofficial websites, since they can open potentially malicious websites or cause unwanted downloads and installations. Such ads might also appear on legitimate websites. Remove any suspicious, unwanted, unknown extensions, plug-ins and add-ons installed on the browser, and programs of this kind installed on the operating system. If your computer is already infected with GroupSource, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
