Beware the Trojan horse
Malware is software designed to maliciously interfere with the regular operation of computers or mobiles. This includes the destruction or gathering of data, presenting unwanted advertising, or rendering a device vulnerable to external control. There were 5.5 billion malware attacks in 2022 alone, down from 10.5 billion in 2018.
Trojan horses are the most common methods of infection, in which a user is tricked into downloading malware, disguised as a legitimate product.
Malware targeting Windows
While all users of devices connected to the internet are vulnerable to malware infections, certain systems are more vulnerable. Malware developers target windows-based systems more than any other, with 83.45 percent of newly detected malware programs in the first quarter of 2020 targeting machines running Windows. This is not to say that users of MacOS are immune, with malware such as Flashback, Macontrol, and Shlayer all designed to infect systems running MacOS.
