The majority of malware is spread through social engineering, targeting users with limited computer security knowledge, particularly among Windows users. Windows has a larger user base, with approximately 1.6 billion devices and over 70% market share, making it a prime target for malware. In contrast, Macs account for about 15% of the market and benefit from robust security protocols, while Linux holds around 5% and its users generally possess higher technical expertise. Windows allows many applications to run with administrator access by default, which can create vulnerabilities, whereas Mac and Linux require explicit permissions for actions, enhancing security. Apple uses digital signatures and sandboxing to protect against malicious software, while Windows' security features are often limited to Pro and Enterprise editions. User behavior and knowledge significantly influence the likelihood of encountering malware, regardless of the operating system used.
