Intego has a range of dedicated apps and plans for both Windows and Mac. The Mac app is far more extensive than the Windows one, with extra features like a Mac optimizer and parental controls. There used to be an iOS antivirus as well, but Apple pulled it from the App store. If you already own it you can still get support, but otherwise, you can only scan iOS devices for malware by connecting them to your Mac first. Then run a scan while both are connected, and Intego will search your iOS device as an external drive.
