What is a common way malicious code can get into your system?

• A. Opening a harmless screensaver
• B. Clicking an e-mail link or attachment
• C. Running antivirus software
• D. Using a trusted program downloaded from a reputable source

Answer: (B)

The key idea is that user interaction with email is a primary path for malware to enter a system. Attackers frequently embed malicious code in email attachments or place harmful links inside messages. When you click a link or open an attachment, the payload can download and install malware or trigger a drive-by download, often hiding as something legitimate like an invoice or receipt. That combination of social engineering and a link or attachment is what makes this a common infection method. Running antivirus software and downloading programs from reputable sources are protective actions that reduce risk, not typical ways malware gets in. Opening a screensaver labeled as harmless is generally not a dependable route for infection, especially if it’s truly safe.
