How to remove 56d2n4d.com from browser settings
Written by Tomas Meskauskas on (updated)
What is 56d2n4d.com?
56d2n4d.com is the address of a fake search engine. Generally, fake search engine addresses are promoted through browser hijackers. Apps of this type promote these bogus addresses by changing certain browser settings. 56d2n4d.com is promoted through an application called DefaultProgress, which is classified as adware (it functions as adware and a browser hijacker).
This app is designed to promote 56d2n4d.com, serve advertisements, and collect sensitive information. Commonly, users download and install apps such as DefaultProgress inadvertently and, for this reason, they are categorized as potentially unwanted applications (PUAs).
56d2n4d.com is classified as a fake search engine, since it provides results generated by Yahoo (it redirects users to search.yahoo.com). The app which promotes it (DefaultProgress) achieves this by changing certain browser settings.
Typically, fake search engines are promoted by assigning their URLs as the address of the default search engine, homepage, and new tab. Therefore, users are forced to visit a specific address (in this case, 56d2n4d.com) when they open a browser, new tab or enter search queries into the URL bar.
Typically, fake search engines can be removed from browser settings only when the app (in this case, DefaultProgress) that promotes them is no longer installed. As mentioned, DefaultProgress functions as browser hijacker and adware (it serves advertisements).
In most cases, these apps serve banners, surveys, coupons, pop-ups and other ads that, if clicked, can open untrusted web pages or even cause download/installation of unwanted applications. DefaultProgress can also read sensitive information from browsers such as credit card details, passwords, telephone numbers, etc.
The developers could misuse this information to steal identities plus email, social media and other personal accounts, make fraudulent purchases and transactions, and for other malicious purposes. Therefore, DefaultProgress should never be downloaded or installed.
Do not use 56d2n4d.com as a search engine. Note that DefaultProgress might be one of a number of PUAs designed to promote 56d2n4d.com.

Some more examples of fake search engines similar to 56d2n4d.com are z6airr.com, searchiing.com and 0yrvtrh.com. Typically, they appear in browser settings after installation of adware and/or browser hijackers such as DefaultProgress. As mentioned, users often download and install these apps inadvertently.
How did DefaultProgress install on my computer?
Research shows that DefaultProgress is distributed through the installer of an unofficial activation tool for Adobe Photoshop. Note that it is illegal to use third party, unofficial tools to activate licensed, legitimate software.
Unwanted downloads and installations often happen through the download/installation set-ups of other software (when PUAs are included as 'additional offers'). In most cases, offers to download and/or install PUAs are listed (and can be declined) in "Advanced", "Custom" or other settings of the set-ups.
Many users fail to check and change these, thereby agreeing by default with offers to download or install PUAs. Sometimes unwanted download and installations happen when users click deceptive advertisements designed to run certain scripts.
How to avoid installation of potentially unwanted applications
Check all "Advanced", "Custom" and other options/settings of the download/installation setup, and decline offers to download or install unwanted apps before finishing the process. Download software from official, trustworthy websites and via direct links.
Tools and sources such as third party downloaders, installers, Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites, etc. can be used to distribute unwanted, potentially malicious apps. Do not click ads that are displayed on dubious web pages, since they can open untrusted websites or even cause unwanted downloads and installations.
Remove any unwanted, suspicious extensions, add-ons, and plug-ins that are already installed on the browser, and software of this kind that is installed on the operating system. If your computer is already infected with browser hijackers, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
