Windows has traditionally been the operating system most threatened by cybercriminals, mainly due to its high penetration rate on desktop computers around the world. However, more and more people are buying Mac computers, which are powered by the macOS operating system, so it is not surprising that attacks by cybercriminals have increased on Apple devices in recent years. One such example is Silver Sparrow, a malware that infected more than 30,000 macOS devices in 2021.

How to know if your Mac has a virus or malware

One sign that your Mac is running slower than usual is the spinning color wheel, which indicates that your computer is trying to do too many things at once. Also, your Mac may behave erratically, freezing and rebooting suddenly.
  2. Browser home page has changed: Another symptom that your Mac is infected is that the home page of the browser has changed. The browser may also start to crash regularly or even become unresponsive.

Although these are some of the most common symptoms to tell if your Mac is infected, viruses and malware can run silently in the background. This makes them more difficult to detect.
