How to remove ConnectionFormat adware from Mac?

What is ConnectionFormat?

ConnectionFormat is an adware-type application that possesses browser hijacker qualities. It is designed to run intrusive advertisement campaigns, make modifications to browser settings and promote fake search engines. On Safari browsers ConnectionFormat promotes 0yrvtrh.com and search.adjustablesample.com - on Google Chrome browsers. Due to the dubious methods used to distribute this app, it is also categorized as a PUA (Potentially Unwanted Application). Furthermore, most PUAs (adware and browser hijackers included) spy on users' browsing activity and collect sensitive information extracted from it.

ConnectionFormat adware

Adware enables the placement of pop-ups, banners, surveys, full-page and other intrusive adverts - typically, on any visited website. The ads overlay webpage content and slow down the browsing speed. Aside from being a nuisance, intrusive advertisements are deemed to be a threat to device/user safety. Once clicked on, these adverts redirect to unreliable/malicious sites and some can even stealthily download/install software (e.g. PUAs). Browser hijackers can assign the addresses of fake web searchers as browsers' homepage, default search engine and new tab/window URLs. Hence, a browser hijacker installed: new browser tabs/windows opened and web searches done via the URL bar - redirect to the promoted address. ConnectionFormat promotes 0yrvtrh.com (on Safari) and search.adjustablesample.com (on Google Chrome) in this manner as well. Illegitimate search engines are usually unable to provide search results, so they tend to redirect to Yahoo, Bing, Google and other genuine one. Browser hijackers can also undo any changes users attempt to make to their browsers, if they allow access to the settings in the first place. As mentioned in the introduction, most PUAs have data tracking abilities. Information of interest includes: URLs visited, pages viewed, search queries typed, IP addresses, geolocations, and other personally identifiable details. The gathered data is then shared with and/or sold to third parties (potentially, cyber criminals). In summary, presence of unwanted software can result in system infections, financial losses, serious privacy issues and even identity theft. To protect device integrity and user privacy, all suspect applications and browser extensions/plug-ins must be eliminated immediately upon detection.

ExpandedSkillAccessibleDataLookup and CoordinatorBoost are a couple examples of other adware-type apps.They appear ordinary and offer a broad range of "handy" functionalities. However, the advertised features are seldom operational. This is true of nearly all PUAs. The sole purpose of unwanted software is to generate revenue for the developers; hence, functionality and user safety are irrelevant. Instead of delivering on any promises, PUAs can run intrusive ad campaigns, hijack browsers, cause redirects and collect private information.

How did ConnectionFormat install on my computer?

PUAs are proliferated via download/installation setups of other software - this false marketing technique is called "bundling". By rushing through download/installation processes (e.g. by ignoring terms, skipping steps and sections, etc.) - users risk unintentionally allowing bundled content into their devices. Select PUAs have "official" promotional sites, from which they can be downloaded. Intrusive advertisements can infiltrate these applications into systems as well. When clicked on, they can execute scripts to download/install PUAs without user consent.

How to avoid installation of potentially unwanted applications?

It is recommended to research software products before download/installation. Only official and verified download channels must be used. Untrustworthy sources, like: unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - often offer deceptive and/or bundled content. Download/Installation processes must be treated with cation; that entails - reading terms, studying all available options, using the "Custom" or "Advanced" settings and declining additional apps, tools, features, and so on. Intrusive adverts typically appear legitimate, however they redirect to various questionable webpages (e.g. pornography, gambling, adult-dating, etc.). Should users experience ads and/or redirects of this kind, they must inspect their devices and remove all suspicious applications and browser extensions/plug-ins without delay. If your computer is already infected with ConnectionFormat, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
