How to remove apps that are designed to promote pages like oc-protection[.]com from Mac?

What is oc-protection[.]com?

There are many websites like oc-protection[.]com on the Internet. As a rule, they are designed to display some fake virus notification to trick users into installing some potentially unwanted application (PUA) so they could remove a virus (or viruses) that those pages have supposedly detected on a device. It is worthwhile to mention that users do not visit pages like oc-protection[.]com intentionally. Typically, such pages get opened via clicked deceptive ads, visited untrustworthy pages or by already installed potentially unwanted applications.

oc-protection[.]com scam

There are at least two variants of the oc-protection[.]com website. One of them displays a fake notification saying that a device is infected with a Trojan and urging users to remove it as soon as possible, otherwise it will compromise accounts, photos and payment data. Another variant does not display a deceptive notification, it simply offers to protect privacy online with the Norton Secure VPN & Proxy VPN - a legitimate application. Although, websites like oc-protection[.]com should never be trusted even if they are used to advertise legitimate apps. All applications should be downloaded only from/via official, trustworthy websites. As mentioned in the previous paragraph, it is common that pages like oc-protection[.]com are promoted through potentially unwanted applications. However, it is common that PUAs are designed not only to open shady pages but also to function a adware-type apps and/or browser hijackers.

It is common that PUAs are designed to promote an address of some fake search engine by changing browser settings such as the address of a default search engine, homepage and/or new tab. Also, they can be designed to serve advertisements. For example, coupons, banners, surveys, pop-ups. It is common that those apps, if clicked, open various untrustworthy pages. In some cases they are capable of running scripts that are designed to cause download and/or installation of some unwanted software. Additionally, they PUAs can function as data collectors. More often than not they target browsing data like IP addresses, entered search queries, addresses of visited pages, geolocations. However, they can be designed to gather sensitive, personal details as well.

More examples of untrustworthy pages that are designed to trick visitors into downloading and installing some application are appleconnect.safellk[.]com, securitymobile[.]club and security-update-required[.]com. It is worthwhile to mention that in most cases users download and install apps that are designed to promote such pages unknowingly. A couple of methods that are used to distribute such apps are described in the next paragraph.

How did potentially unwanted applications install on my computer?

It is common that potentially unwanted apps are distributed by integrating them them in download and/or installation setups of other programs. This distribution method is called "bundling". In such cases developers include PUAs as additional offers, these offers can be declined via options/settings of settings like "Advanced", "Custom" or by unticking certain checkboxes. However, not all users check and change teh aforementioned settings when they download and/or install programs and that is how they download and/or install included PUAs as well. Also, in some cases such downloads and/or installations can be caused by clicking advertisements that are designed to execute certain scripts.

How to avoid installation of potentially unwanted applications?

It is recommended to inspect download and installation setups that have settings (e.g., "Custom", "Advanced") or checkboxes. It is common that they can be used to decline offers to download and/or install additionally included, unwanted apps. Also, it is recommended not to use third party downloaders, installers, Peer-to-Peer networks (like torrent clients, eMule), unofficial sites, and other similar sources as tools to download or install any software. Files and programs should be downloaded from official, trustworthy websites, and via direct links. Intrusive advertisements that appear on suspicious, questionable websites should not be clicked as well - more often than not those ads re designed to promote various untrustworthy websites or even to download, installation of some unwanted application by running certain scripts. If there are any unwanted apps (extensions plug-ins, and/or add-ons) installed on a browser, then they should be removed from it. Programs of this kind that are installed on a computer should be uninstalled too. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
