How to remove apps designed to promote ustrack[.]online?

What is ustrack[.]online?

Ustrack[.]online is a deceptive website designed to trick visitors into downloading and installing some potentially unwanted application (PUA) or multiple apps. Like most websites of this type, it displays a fake virus notification claiming that a device (iPhone) has been infected and encourages to remove detected viruses as soon as possible. In most cases, websites like ustrack[.]online are promoted through untrustworthy websites, advertisements or potentially unwanted applications - users do not visit pages like ustrack[.]online intentionally.

ustrack[.]online scam

Ustrack[.]online displays a fake iOS system notification and a fake virus alert claiming that a device has been infected with three viruses and its battery has been damaged. The main purpose of this scam website is to trick visitors into believing that if they do not remove detected malware immediately with the app that can be downloaded from it, then installed malware will cause more damage to their device. It is strongly recommended not to trust websites like ustrack[.]online and download software through them. Websites of this type can be used to trick visitors into downloading and installing adware, browser hijackers, and other unwanted applications. In some cases, they can be used to distribute malicious applications. It is worth mentioning that pages like ustrack[.]online can be used to advertise apps available on App Store (legitimate applications). However, ustrack[.]online and similar pages should not be trusted even if they promote trustworthy apps. Another detail about these pages is that most of them are designed to look like the official Apple pages (e.g., Apple Security pages). Nevertheless, none of them have anything to do with the official Apple pages.

Quite often, websites like ustrack[.]online are promoted through potentially unwanted applications. Usually, users download and install apps of this kind inadvertently. It is important to mention that many PUAs can generate advertisements and collect various information. They generate banners, coupons, surveys, pop-up ads, etc. Their ads tend to be designed to promote questionable websites. Sometimes, those ads cause unwanted downloads or even installations by executing certain scripts. Therefore, it is not safe to click ads that PUAs generate. Furthermore, most PUAs collect browsing-related details. For example, geolocations, entered search queries, URLs of visited websites, Internet Protocol addresses. Although, sometimes they can access credit card details, passwords, and other details that may be misused to steal accounts, make unauthorized purchases, transactions, and so on.

To summarize, websites like ustrack[.]online use deceptive techniques to trick visitors into downloading and installing unwanted or unnecessary software. Most of them display fake virus or error notifications pushing visitors to solve the "problem" as soon as possible. As mentioned in the second paragraph, these pages usually are designed to look like official websites created by legitimate companies like Apple, Microsoft, etc. There are many pages like ustrack[.]online on the Internet. Some examples are "(10) Viruses Were Detected On Your iPhone", "Your iPhone Was Hacked After Visiting An Adult Website", and "Hackers are watching you!". All these pages should be ignored.

How did potentially unwanted applications install on my computer?

One of the most popular ways to trick users into unknowingly downloading or installing PUAs is to integrate PUAs in downloaders, installers of other programs as extra offers. In other words, to bundle PUAs with other programs that users are likely to download and install intentionally. In most cases, unwanted offers can be found (and declined) in "Custom", "Advanced" and other settings or by unticking ticked checkboxes. When users download or install programs without changing those settings, they agree to download or install all the included PUAs. Sometimes users download or install PUAs through deceptive advertisements that are designed to execute certain scripts. Although, only if users click those ads.

How to avoid installation of potentially unwanted applications?

Applications, files should not be downloaded from unofficial pages, via third-party downloaders, Peer-to-Peer networks like torrent clients, eMule, and other sources of this kind, or installed via third-party installers. It is common that their users download or install unwanted, potentially malicious software. It is recommended to use only official pages and direct links. Downloaders and installers with settings like "Custom", "Advanced" (or ticked checkboxes) can be used to distribute potentially unwanted applications. Therefore, they should be checked for unwanted offers before finishing download or installation processes. Advertisements appearing on untrustworthy websites should not be trusted. In most cases, those ads are used to promote various untrustworthy, potentially malicious websites. Sometimes, those ads can download or even install PUAs. All unwanted, suspicious extensions, plug-ins, or add-ons installed on a web browser or programs of this kind installed on the operating system should be removed. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
