There’s no such thing as a 100% safe computer, and this implies to Apple computers as well. A system believed to be immune to viruses and malware, has a list of its very own attacks and security threats.
While it is true that Macs are more secure than PCs, they’re still vulnerable to online threats.
Crossrider aka OSX/Shlayer
Mac users are being warned of this adware that poses as Adorbe Flash Player installer. The fake Flash Player installer releases a copy of Advanced Mac Cleaner which notifies the user in Siri’s voice that there’s a problem on the system.
