How to prevent redirects to 'Your Mac OS Might Be Infected' on Mac computers

What is 'Your Mac OS Might Be Infected'?

Many deceptive websites display fake pop-up messages and trick visitors into downloading and installing dubious applications. They often display an identical pop-up window and message. This web page is one example and is used to distribute Smart Mac Booster, however, it might also be used to promote other, similar applications. Typically, visitors are encouraged to install the app and use it for removal of detected malware. We advise against downloading or installing apps that are advertised though websites of this type. Browsers often open these sites due to potentially unwanted applications (PUAs) installed on them.

Once opened, this deceptive site displays a pop-up window with a notification stating that the MacOS might be infected. To begin the repair process, visitors are urged to click the 'OK' button. The main page states that the operating system (in this case, MacOS High Sierra) is infected with three viruses. To avoid further system damage (loss of photos, apps, and other data), visitors are encouraged to remove the viruses immediately. It is also mentioned that banking information is at risk. Visitors are supposedly able to remove detected malware after scanning their systems by clicking the 'Scan Now' button. This web page runs a fake scanner, which detects certain malicious software and then offers to remove it by downloading the maccleaner.pkg file, which it uses to install the Smart Mac Booster app. In fact, this web page might also be used to promote other dubious apps. Some examples of apps of this kind are Mac Clean Pro, Advanced Mac Booster, and Qbit Mac Speedup. In any case, do not download or install any apps that are distributed through dubious sites such as this.

Apps that force browsers to open deceptive and untrustworthy websites often gather information relating to users and display unwanted ads. They record details such as IP addresses, geolocations, addresses of visited websites, entered search queries, etc. Some PUAs might be designed to collect personal information. Typically, developers share the details with third parties who misuse them to generate revenue. Furthermore, these apps might serve coupons, surveys, banners, pop-ups, and other intrusive, unwanted ads. These usually conceal underlying content of visited websites. Furthermore, people who click them are redirected to dubious web pages, or they cause download/installation of unwanted applications.

'Your Mac OS Might Be Infected' is a message that is displayed in pop-up windows on many deceptive web pages, which are used to trick visitors into downloading and installing untrustworthy software. Other examples of similar sites are Mondaysunday, apple.com-guard-device[.]live, and apple.com-optimize-mac[.]live. We recommend that you ignore these websites and never download anything from them. PUAs (apps that force browsers to open the web pages) are usually advertised as 'useful applications', however, most are useless and cause only problems. People who have them installed on their systems risk problems with browsing safety, privacy, or they might even have their identities stolen.

How did potentially unwanted applications install on my computer?

People often cause download/installation of PUAs unintentionally. This happens when they click deceptive ads that execute scripts designed to cause unwanted downloads/installations, or when developers use a deceptive marketing method called 'bundling'. When they distribute PUAs using this method, they include unwanted apps into the set-ups of other software. They hide offers to download or install additional apps in 'Custom', 'Advanced', 'Manual', and other similar settings. In many cases, people cause installation/downloads of various unwanted apps simply by leaving all available settings unchecked and unchanged.

How to avoid installation of potentially unwanted applications

Do not download or install programs using third party downloaders, Peer-to-Peer networks such as torrent clients, eMule, untrustworthy (unofficial) websites, and so on. The best way is to use official websites and direct download links. Check 'Advanced', 'Custom' and other settings of any download or installation setup and deselect offers to download or install unwanted applications. Do not click intrusive advertisements, since these can redirect to untrustworthy websites or lead to unwanted downloads/installations. If the browser causes unwanted redirects or displays ads, check for unwanted extensions, plug-ins, and add-ons installed on it. Also check the list of installed programs on the computer. Remove all unwanted, suspicious software immediately. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
