How to remove apps that open skyprize sites from Mac?

What is skyprize?

Skyprize is one of the families of various deceptive, potentially malicious websites. For example, pages that are designed to trick visitors into downloading and installing some potentially unwanted applications (PUAs) like browser hijackers, adware-type apps, or even malicious software like ransomware, Trojans. Also, families like skyprize often include pages that are designed to deceive visitors into providing sensitive information. Either way, none of those pages are trustworthy. Usually browsers open such pages automatically because some PUA is installed on them.

skyprize scam

One of the pages that belongs to skyprize family is very similar to "Dear Safari User, You Are Today's Lucky Visitor" (and a great number of other deceptive pages). These pages suggest that visitors can win (or have won) some prize and encourage them to claim a prize by participating in a survey. Scammers behind such pages attempt to extract confidential information (like credit card details) that could be misused to generate revenue in one way or another way. Visitors who trust such pages can become victims of identity theft, suffer monetary loss and other problems. Furthermore, it is very likely that skyprize family includes pages designed to distribute various PUAs (e.g., adware, browser hijackers) and/or fake Adobe Flash Player installers that are designed to install them. Adware-type apps display ads in forms of banners, coupons, pop-ups, surveys, and cover contents of websites thats users visit. If clicked, they usually open untrustworthy pages or cause downloads, installations of various PUAs by executing certain scripts. Browser hijackers hijack browsers by changing their settings. Typically, they set address of some fake search engine as an address of default search engine, homepage and new tab and prevent users from undoing these changes. Both adware-type apps and browser hijackers can be designed to collect various browsing data, or even sensitive, personal details. What is worse, skyprize may load pages that are designed to deceive visitors into infecting their computers with ransomware or other malicious program like a Trojan. Ransomware is a malicious software that encrypts files so that victims could not decrypt them without a tools that usually can be purchased only from cyber criminals who designed that malware. Trojans often are designed to cause chain infections by infecting already infected computer with some other malware. To sum up, no matter what type of page is a part of skyprize, it cannot be trusted.

A couple of examples of other families like skyprize are yourprizeszx, prizeseeker and prizesfinder. If trusted, pages that are part of such families could lead to various problems. For example, unwanted downloads, installations, monetary loss, identity theft, issues related to online privacy, browsing safety, etc. As mentioned in the introduction, quite often untrustworthy pages are opened by browsers that have some PUA (or PUAs) installed on them.

How did potentially unwanted applications install on my computer?

In most cases PUAs get downloaded and/or installed when people intentionally (or unintentionally) click some deceptive advertisement or download, install programs without changing settings that are available in their setups. Typically, developers distribute PUAs by using a deceptive marketing method called "bundling". It means that they include those apps in various download and/or installation setups and present them as additional offers. Typically, those offers can be found in "Advanced", "Custom", and other settings of setups. Unfortunately, people often leave them unchanged. By doing so they agree with offers to download and/or install unwanted applications that are included in a certain setup. Clicked ads can cause downloads and/or installation of PUAs when they are designed to execute certain scripts. However, they cannot do that without being clicked.

How to avoid installation of potentially unwanted applications?

We recommend to always check "Custom", "Advanced", "Manual" and other similar settings of any download or installation setup and make sure that it does not have any unwanted apps included in it. If it contains offers to download and/or install unwanted software, then those offers should be declined before finishing download and/or installation process. Also, it is not recommended to download (and install) software from untrustworthy, unofficial websites, through torrent clients, eMule (or other Peer-to-Peer networks), third party downloaders, installers, and so on. The safest way to download software is to use official websites and direct download links. Intrusive ads (especially if displayed on shady pages) should not be clicked. Quite often those ads open questionable websites or cause unwanted downloads, installations. If there are any unwanted or suspicious apps (extensions, add-ons or plug-ins) already installed on a browser, then they should be removed as soon as possible. The same should be applied to programs of this kind that are installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
