Tips for Apple-warning.com POP-UP Scam removal
Apple-warning.com POP-UP Scam is displayed on a rogue page –Apple-warning.com. It says that the visitor's device is infected with viruses and encourages them to download and install some potentially unwanted application (PUA) that supposed to remove detected threats. Typically, users do not visit this type of pages with purposes. They end up to this site as a redirect when visiting any unprotected site or when some potentially unwanted app already installed on their device.
The text in the Apple-warning.com POP-UP Scam page states that the user's iPhone and its battery are infected and damaged by three viruses. It encourages removing these viruses soon or, otherwise they will cause even more damage. It recommends an application called Super BlockerAd to fix the issues arisen.

How to remove 'Mac OS Alert' scam from Mac?
What is the 'Mac OS Alert' scam?
'Mac OS Alert' is a scam, promoted on various deceptive websites. This scheme claims that visitors' devices may be infected and recommends a quick scan. The fake scan then comes up with several nonexistent viruses and states that the anti-virus suite has to be updated. It must be emphasized that no webpage can actually detect threats/issues present on systems; hence, any that make such proclamations - are scams. Schemes of this kind are designed to promote a variety of untrustworthy or even dangerous software. These scams commonly promote various potentially unwanted applications (e.g. fake anti-viruses, adware, browser hijackers, etc.) and in some cases they even proliferate malware (e.g. trojans, ransomware, etc.). Few users access deceptive sites intentionally, most access them via mistyped URLs, redirects caused by intrusive advertisements or by PUAs (Potentially Unwanted Applications).
When a website running the 'Mac OS Alert' scam is accessed, it displays several pop-up windows. The foremost pop-up informs visitors that their Macs may be infected. To detect the supposed viruses, the scam recommends users to scan their devices. The fake scan will take 10 seconds. To perform the scan and continue, visitors are told to click 'OK' to continue. Once this window is closed, the background pop-up states that users' devices are supposedly infected with five viruses. Immediate action is required - the anti-virus software must be updated. Visitors are urged to update their anti-virus suites by clicking 'Proceed', followed by 'Download' on the next page - to install the latest updates. As mentioned in the introduction, all of the information provided by 'Mac OS Alert' is false; i.e. the threats detected by this scheme are fake and merely used as bait to trick users' into downloading/installing and/or purchasing the promoted products. To summarize, by trusting the 'Mac OS Alert' scam, users can experience system infections, severe privacy issues, financial losses and even identity theft.
Scams like 'Mac OS Alert' typically promote various PUAs. These applications tend to appear legitimate and harmless; they may even be disguised as genuine existing products. Fake anti-virus tools are amongst the most popular apps endorsed in this fashion. Illegitimate anti-viruses require activation (i.e. purchase) to perform the advertised functions, yet even after activation - they remain nonoperational. Some PUAs can force-open unreliable, deceptive and malicious sites. Adware-types run intrusive advertisement campaigns, i.e. deliver various pop-ups, banners, coupons and other ads. They diminish the browsing activity, as they overlay page content and slow down the browsing speed. Once clicked on, intrusive adverts redirect to dangerous websites and some can even stealthily download/install software. Another PUA type called browser hijackers make modifications to browser settings in order to promote fake search engines. Hence, every new browser tab/window opened and web search done via the URL bar - redirect to the address of the promoted web searcher. Illegitimate search engines are seldom able to generate search results, so they tend to redirect to Google, Yahoo, Bing and other genuine ones. Browser hijackers can also restrict/deny access to the browsers' settings and/or undo any permitted changes made. What is more, most PUAs (regardless of type) can track data. They monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect sensitive information extracted from it (IP addresses, geolocations and other details). The gathered data usually contains personally identifiable information. In summary, presence of unwanted software on devices endangers device integrity and user integrity. Therefore, it is strongly advised to remove all suspect applications and browser extensions/plug-ins immediately upon detection.

How did potentially unwanted applications install on my computer?
Select PUAs have 'official' download webpages, which are often promoted by deceptive/scam sites. These applications are also distributed via download/installation setups of other programs. This false marketing method of packing ordinary software with unwanted or malicious additions - is called 'bundling'. Rushed download/installation processes (e.g. ignored terms, skipped steps and sections, etc.) increase the risk of inadvertently allowing bundled content into the system. Intrusive adverts proliferate PUAs as well. Once clicked on, the ads can execute scripts to make stealthy downloads/installations.
How to avoid installation of potentially unwanted applications?
It is advised to research software prior to download/installation and/pr purchase. Only official and verified download channels must be used. Since untrustworthy download sources, e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - commonly offer harmful and/or bundled content. When downloading/installing, it is recommended to read terms, explore all available options, use the 'Custom/Advanced' settings and opt-out from supplementary apps, tools, functions and other additions. Intrusive advertisements appear legitimate, however they redirect to questionable webpages (e.g. gambling, pornography, adult-dating, and so on). In case of encounters with such ads and/or redirects, the system must be checked and all suspicious applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
