Potentially unwanted applications deliver coupon, banner, pop-up, and other intrusive advertisements. 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 ads can lead to infectious websites and execute scripts that download and install malware. Therefore, clicking them risks various computer infections. Potentially unwanted applications are also known to record information relating to browsing activity. Collected data (IP addresses, URLs visited, pages viewed, search queries, and so on) typically includes personal details that developers share with third parties (potentially, cyber criminals) who misuse it to generate revenue. The presence of these applications might lead to serious privacy issues or even identity theft. Remove them immediately.

There are dozens of fake error messages similar to "Mac iOS Security At Risk Error Code: HT201155". All claim that the system is damaged , however, these claims are merely attempts to trick unsuspecting users into paying for unnecessary tech support or purchasing useless software (typically fake anti-virus suites). By offering "useful features", PUAs often convince users that they are legitimate and useful, however, these apps are designed only to generate revenue for the developers. Rather than enabling the functionality promised, they gather information, cause redirects, and deliver ads, thereby posing a direct threat to your privacy and Internet browsing safety.

How did potentially unwanted applications install on my computer?

In some cases, potentially unwanted applications have official download websites, however, due to the lack of knowledge and careless behavior of many users, these apps often infiltrate systems without consent. Most are distributed using intrusive advertisements and a deceptive marketing method called "bundling" (stealth installation of potentially unwanted applications together with regular software/apps). Developers are not honest enough to disclose PUA installations properly. Therefore, all are hidden within "Custom/Advanced" settings (or other sections) of the download/installation processes. In this way, users expose their systems to risk of various infections by clicking advertisements and skipping most download/installation steps. This behavior often leads to inadvertent installation of PUAs.

How to avoid installation of potentially unwanted applications?

To prevent system infiltration by potentially unwanted applications, pay close attention during the download/installation processes and when browsing the Internet. Carefully analyze each download/installation step and opt-out of all additionally-included programs. We also recommend that you avoid using third party downloaders/installers, since developers monetize them by promoting PUAs. Software should be downloaded from official sources only, using direct download links. Developers invest a great deal of time and resources into intrusive ad design, thereby making them seem legitimate, but most redirect to dubious websites (pornography, adult dating, survey, etc.) If you encounter these redirects, check the list of installed apps/browser plug-ins and eliminate any suspicious entries. The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
