How can you safeguard your computer from malware?

• A. By avoiding the internet
• B. By using antivirus software and keeping it updated
• C. By closing all applications regularly
• D. By installing multiple operating systems

Answer: (B)

Using antivirus software and keeping it updated is a critical strategy for safeguarding your computer from malware. Antivirus programs are specifically designed to detect, quarantine, and eliminate various forms of malware, such as viruses, worms, trojans, and spyware. They continuously scan files and incoming data to identify any malicious content before it can infect your system.

Keeping the antivirus software updated is equally important because new malware threats are constantly being developed by cybercriminals, and updates ensure that the software can recognize and defend against the latest threats. Regular updates provide access to the newest virus definitions and security improvements, which significantly enhances the protection offered by the antivirus software.

The other strategies mentioned, such as avoiding the internet or closing applications regularly, do not adequately address the potential for malware to invade a computer. Avoiding the internet is impractical for most users, and simply closing applications does not prevent malware from gaining access to the system in the first place. Installing multiple operating systems can introduce complexities and may not provide a straightforward method for malware defense. Thus, using and consistently updating antivirus software is the most effective measure for maintaining computer security against malware.
