How to remove ProntoApp from Mac?

What is ProntoApp?

ProntoApp is a rogue adware-type application that performs various malicious actions on infected machines. On initial inspection, ProntoApp may not seem to be suspicious or harmful, however, it usually infiltrates computers without users' consent. Furthermore, it can cause redirects, deliver intrusive advertisements, modify browser options, reduce overall system performance, and cause a number of other problems.

ProntoApp adware

This application is related to two fake search engines (home.convertpdfpronto.com and home.prontovideoconverter.com) and is used to cause unwanted redirects. For instance, it might hijack various browsers (Safari, Mozilla Firefox, Google Chrome, etc.) and modify the homepage, new tab URL, and other settings. In doing so, ProntoApp forces users to visit other websites when they enter a search query or open a new browser tab/window. These redirects can significantly diminish the browsing experience. This app is also known for its capability to modify DNS settings. As with most adware, ProntoApp is also likely to deliver advertisements, such as coupons, banners, pop-ups, and similar. These are delivered using tools that enable placement of third party graphical content on any site. Therefore, they often conceal underlying content, thereby significantly diminishing the browsing experience. In addition, intrusive advertisements often redirect to dubious websites and some even execute scripts designed to download/install other unwanted apps. Therefore, even accidental clicks can result in high-risk computer infections. Adware-type applications are also likely to record data relating to browsing activity. The list of data types collected by these applications commonly includes IP addresses, website URLs visited, web pages viewed, search queries, etc. The information often includes personal details that developers share with third parties (potentially, cyber criminals). These people generate revenue by misusing private information. Therefore, information tracking might lead to serious privacy issues or even identity theft. In summary, ProntoApp is a dangerous application and its presence can lead to a number of issues. We strongly recommend that you eliminate this application immediately.

There are dozens of rogue applications that share many similarities with ProntoApp including NameSync, StudyDisplay, and PathBrand - these are just some examples from many. By offering various "useful features", these applications attempt to give the impression of legitimacy and trick users to install. Following infiltration, however, they provide no value for regular users. Unwanted applications cause redirects, gather information, and deliver intrusive advertisements, thereby significantly diminishing the browsing experience and posing a threat to your privacy and computer safety.

How did ProntoApp install on my computer?

As mentioned, this application usually infiltrates computers without users' consent. Developers proliferate it using intrusive advertisements and especially a deceptive marketing method called "bundling" - stealth installation of third party applications together with regular (typically free) software. Developers know that users often rush download/installation processes and skip steps. Therefore, all information regarding modification of browser options is hidden behind "Custom/Advanced" settings (or other sections) of the download/installation processes. By carelessly clicking on advertisements, rushing, and skipping download/installation steps, many users expose their systems to risk of various infections and compromise their privacy. Fake software updaters/installers are also used in a similar manner. They inject unwanted applications by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than updates.

How to avoid installation of potentially unwanted applications?

Be very cautious when browsing the Internet and downloading/installing/updating software. Carefully analyze each window of the download/installation dialogs using the "Custom" or "Advanced" settings. Opt-out of additionally-included programs and decline offers to download/install them. Avoid using third party downloaders/installers, since most are monetized using the "bundling" method. Keep installed applications and operating systems up-to-date, however, use only implemented functions or tools provided by the official developer. Note that intrusive advertisements usually seem legitimate, since developers invest many resources into their design. In fact, they typically redirect to dubious websites (gambling, adult dating, pornography, and similar). If you experience these ads/redirects, remove all suspicious applications and browser plug-ins. If your computer is already infected with ProntoApp, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
