How to avoid redirects to "Mac System currently outdated and corrupted" on Mac

What is "Mac System currently outdated and corrupted"?

"Mac System currently outdated and corrupted" is a notification on a deceptive scam site, which is used to trick people into installing a dubious app called My Mac Speedup. Visitors supposedly use this app to fix an 'issue' that was detected by this scam site. We strongly advise that you do NOT trust websites of this type or apps that they promote. If the browser opens these web pages regularly, it is likely that a potentially unwanted application (PUA) is installed on the system and is responsible.

Mac System currently outdated and corrupted scam

When visited, this website displays a pop-up window with a message stating that the MacOS system is outdated and corrupted, and will automatically erase all system files. To resolve this problem, visitors are encouraged to follow further instructions, however, they can only click the "Continue" button, which is displayed on the background of the web page. If clicked, this opens another website, a download page for the My Mac Speedup application. Apps that are promoted through deceptive websites should not be trusted even if they are not malicious or dangerous in any other way. They are often useless, provide none of the advertised features, and cannot be fully used unless they are activated (usually, by making payments). These scam web pages and dubious apps can never be trusted.

Scam sites and other untrustworthy web pages are generally opened by PUAs installed on the system. Unfortunately, redirects to dubious web pages are not the only problem with these apps. Frequently, PUAs collect information relating to users' browsing activities and display annoying, intrusive advertisements. PUAs record data that usually includes IP addresses, entered search queries, addresses of visited websites, geolocations, and other details of this kind. In most cases, the people responsible for these apps share the details with other parties (potentially cyber criminals) who misuse them to generate revenue. Ads displayed by PUAs include coupons, banners, surveys, pop-ups, etc. People who click them are usually redirected to potentially malicious, deceptive and untrustworthy websites. In some cases, the ads run scripts that download and install other PUAs.

The "Mac System currently outdated and corrupted" scam page is similar to many other websites such as "Your Apple iPhone Is Infected By (17) Viruses", "Your System Is Seriously Damaged, Found (4) Viruses!", and "You Have Been Redirected To Apple Support Page". They are used to trick people into believing that there is an issue with their mobile or desktop devices. They then promote dubious applications that supposedly resolve the problem. PUAs that open these sites are also very similar. They are advertised as legitimate, useful apps, however, most are useless and often lead to various problems relating to browsing safety, privacy, etc.

How did potentially unwanted applications install on my computer?

Typically, people download and/or install unwanted apps through clicked intrusive ads (that cause unwanted downloads or installations) or when software developers use the "bundling" method. Bundling is used to trick people into downloading/installing additional applications together with other regular software. To achieve this, developers hide offers to download or install PUAs in "Custom", "Advanced", and other similar options/settings of the software set-ups. Leaving these settings unchanged accepts the offers (of additional software) in the setup by default.

How to avoid installation of potentially unwanted applications

To avoid unwanted downloads and installations, download software from official websites. Do not use other sources or tools such as third party downloaders/installers, Peer-to-Peer networks, and so on. If set-ups include offers to download or install unwanted applications, dismiss them before completing the download or installation processes. Do not click intrusive ads displayed on dubious web pages (typically, relating to gambling, adult dating, pornography, etc.). Generally, they open potentially malicious websites or run scripts that download or install PUAs. In most cases, browsers open dubious web pages and/or display ads when PUAs are installed on them. To prevent this, uninstall all unwanted apps (extensions, plug-ins, add-ons) on the browser and programs installed on the computer. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
