Stop redirects to the 'Mac System currently outdated and corrupted' scam

Also Known As: Mac System currently outdated and corrupted pop-up
Type: Mac Virus
Damage level: Medium

What is "Mac System currently outdated and corrupted"?

"Mac System currently outdated and corrupted" is a notification on a deceptive scam site, which is used to trick people into installing a dubious app called My Mac Speedup.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Mac System currently outdated and corrupted scam

When visited, this website displays a pop-up window with a message stating that the MacOS system is outdated and corrupted, and will automatically erase all system files.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The "Mac System currently outdated and corrupted" scam page is similar to many other websites such as "Your Apple iPhone Is Infected By (17) Viruses", "Your System Is Seriously Damaged, Found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.

Text in the pop-up window:

How to identify a pop-up scam?

Pop-up windows with various fake messages are a common type of lures cybercriminals use. They collect sensitive personal data, trick Internet users into calling fake tech support numbers, subscribe to useless online services, invest in shady cryptocurrency schemes, etc.

While in the majority of cases these pop-ups don't infect users' devices with malware, they can cause direct monetary loss or could result in identity theft.

Cybercriminals strive to create their rogue pop-up windows to look trustworthy, however, scams typically have the following characteristics:

  • Spelling mistakes and non-professional images - Closely inspect the information displayed in a pop-up. Spelling mistakes and unprofessional images could be a sign of a scam.
  • Sense of urgency - Countdown timer with a couple of minutes on it, asking you to enter your personal information or subscribe to some online service.
  • Statements that you won something - If you haven't participated in a lottery, online competition, etc., and you see a pop-up window stating that you won.
  • Computer or mobile device scan - A pop-up window that scans your device and informs of detected issues - is undoubtedly a scam; webpages cannot perform such actions.
  • Exclusivity - Pop-up windows stating that only you are given secret access to a financial scheme that can quickly make you rich.

How do pop-up scams work?

Cybercriminals and deceptive marketers usually use various advertising networks, search engine poisoning techniques, and shady websites to generate traffic to their pop-ups. Users land on their online lures after clicking on fake download buttons, using a torrent website, or simply clicking on an Internet search engine result.

Based on users' location and device information, they are presented with a scam pop-up. Lures presented in such pop-ups range from get-rich-quick schemes to fake virus scans.

How to remove fake pop-ups?

In most cases, pop-up scams do not infect users' devices with malware. If you encountered a scam pop-up, simply closing it should be enough. In some cases scam, pop-ups may be hard to close; in such cases - close your Internet browser and restart it.

In extremely rare cases, you might need to reset your Internet browser. For this, use our instructions explaining how to reset Internet browser settings.

How to prevent fake pop-ups?

To prevent seeing pop-up scams, you should visit only reputable websites. Torrent, Crack, free online movie streaming, YouTube video download, and other websites of similar reputation commonly redirect Internet users to pop-up scams.

To minimize the risk of encountering pop-up scams, you should keep your Internet browsers up-to-date and use reputable anti-malware application. For this purpose, we recommend Combo Cleaner Antivirus for macOS.

What to do if you fell for a pop-up scam?

This depends on the type of scam that you fell for. Most commonly, pop-up scams try to trick users into sending money, giving away personal information, or giving access to one's device.

  • If you sent money to scammers: You should contact your financial institution and explain that you were scammed. If informed promptly, there's a chance to get your money back.
  • If you gave away your personal information: You should change your passwords and enable two-factor authentication in all online services that you use. Visit Federal Trade Commission to report identity theft and get personalized recovery steps.
  • If you let scammers connect to your device: You should scan your computer with reputable anti-malware (we recommend Combo Cleaner Antivirus for macOS) - cyber criminals could have planted trojans, keyloggers, and other malware, don't use your computer until removing possible threats.
  • Help other Internet users: report Internet scams to Federal Trade Commission.
