How to remove DefaultProgress adware from Mac?

What is DefaultProgress?

DefaultProgress is a piece of rogue software, it is classified as adware and it also possesses browser hijacker traits. Following successful installation, this application runs intrusive advertisement campaigns (i.e. delivers various ads), makes changes to browser settings and promotes fake search engines. DefaultProgress promotes 56d2n4d.com on Safari browsers and search.adjustablesample.com on Google Chrome browsers. Due to the dubious techniques used to distribute DefaultProgress, it is considered to be a PUA (Potentially Unwanted Application) as well. Furthermore, most PUAs (adware and browser hijackers included) spy on users' browsing activity.

DefaultProgress adware

Adware enables the placement of pop-ups, banners, coupons, full-page and other intrusive advertisements - typically, on any visited website. Hence, the ads do not originate from the sites themselves but are delivered by adware installed onto the device. Intrusive adverts seriously diminish the browsing experience, as they overlay page content and slow down the browsing speed. Additionally, upon being clicked, these advertisements redirect to various unreliable/malicious websites and some can even stealthily download/install software (e.g. PUAs). Browser hijackers assign the addresses of fake web searchers as browsers' homepage, default search engine and new tab/window URLs. With such a piece of software installed: every new browser tab/window opened and search query typed into the URL bar - redirect to the promoted search engine. DefaultProgress promotes 56d2n4d.com (on Safari) and search.adjustablesample.com (on Google Chrome) in this manner as well. Fake search engines are seldom capable of providing search results, so they redirect to Google, Yahoo, Bing and other legitimate ones. Browser hijackers can also restrict/deny access to the browser's settings and/or undo any permitted changes made. As mentioned in the introduction, most PUAs have data tracking abilities. They can record browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect personal information (IP addresses, geolocations and other details). This sensitive data is then shared with and/or sold to third parties (potentially, cyber criminals). In summary, presence of unwanted software on devices can result in system infections, financial losses, severe privacy issues and even identity theft. To ensure device and user safety, all suspicious applications and browser extensions/plug-ins must be removed without delay.

SignalBalanceProgressHelperSkilledSystemFrequencySkill - are some examples of other adware-type apps. They appear ordinary and innocuous. Users are enticed into download/installation with offers of various "useful" functionalities. The features are rarely operational and even if they do work - then, not as advertised. In fact, this applies as practically all PUAs. Functionality and user safety are irrelevant, since the only goal of unwanted applications is to generate revenue for the developers. Therefore, instead of delivering on any promises, PUAs can run intrusive advertisement campaigns, hijack browsers, cause redirects and gather personally identifiable information.

How did DefaultProgress install on my computer?

PUAs can be downloaded/installed together with other software. This false marketing method of packing regular products with unwanted or malicious additions - is called "bundling". Rushed download/installation processes (e.g. skipped steps and sections, used "Easy/Express" settings, etc.) - increase the risk of unintentionally allowing bundled content into the system. Intrusive adverts proliferate these applications as well. Once clicked on, the ads can execute scripts to download/install PUAs without user permission. Select PUAs have "official" download webpages.

How to avoid installation of potentially unwanted applications?

It is recommended to research products prior to download/installation and/or purchase. All downloads must be done from official and verified sources. Since untrustworthy channels, like: unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders - often offer deceptive and/or bundled content. When downloading/installing, it is important to read terms, explore all available options, use the "Custom" or "Advanced" settings and opt-out from supplementary apps, tools, features, etc. Intrusive advertisements appear legitimate and harmless, however they redirect to highly dubious websites (e.g. gambling, pornography, adult-dating, and so on). In case of encounters with ads and/or redirects of this kind, users must inspect their devices and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with DefaultProgress, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
