Similar scams in general
Technical support scam websites usually are disguised as legitimate Apple, Microsoft, or other company pages. They claim that a computer is infected or there is another problem that visitors must solve immediately. It is important to mention that cybercriminals can use these pages to trick visitors into infecting their computers with malware.
Examples of similar scams are "Your MAC Has Been Blocked Due To Suspicious Activity!", "Your System Is Infected With 3 Viruses", and "Error Code: #2c522hq8wwj791".
How did I open a scam website?
Websites running pop-up scams (displaying fake security or other alerts) are promoted via other (deceptive) pages, shady advertisements, advertising-supported apps, pages that use rogue advertising networks, browser notifications displayed by dubious websites, etc.
Also, scammers use search engine poisoning techniques to promote their scams. Either way, pages running such scams are not visited on purpose.
How to avoid visiting scam websites?
Do not click on suspicious advertisements or browser notifications (especially when they are displayed by questionable pages). Use official pages and platforms as sources for downloading apps (do not use third-party downloaders, shady pages, P2P networks, etc.). Do not allow dubious pages to show notifications.
It is also advisable to check downloaders/installers for unwanted apps and deselect them before downloading/installing software. If your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate all threats.
