Which practice is discouraged when protecting against malware threats?

Installing software from unverified sources is discouraged as it significantly increases the risk of introducing malware into a system. Software from unverified sources may lack proper security checks and could be bundled with malicious code. This practice stands in stark contrast to utilizing legitimate software sources, which provide verified and safe applications.

By choosing to install software from trusted platforms or providers, users can reduce the likelihood of downloading ransomware, spyware, or other types of harmful software that can compromise security. Additionally, reliable software vendors often provide updates and support that help mitigate security vulnerabilities over time. Keeping software updated and running regular virus scans are also proactive measures that enhance overall protection against malware threats.
