All three elements—internet connection, an operating system, and a logged-on user—can contribute to the vulnerability of a computer system or device to malware, but they play different roles:
Internet Connection: Malware often spreads through the internet, whether via malicious websites, email attachments, or other online vectors. Having an internet connection increases the potential exposure to various types of malware.
Operating System: Malware is often designed to exploit vulnerabilities or weaknesses in operating systems. Regularly updating the operating system with security patches and using security features can help mitigate these risks.
Logged-on User: A user logged on to a system may inadvertently execute or download malicious software. User actions, such as clicking on malicious links, downloading infected files, or falling victim to social engineering attacks, can introduce malware to the system.
