9 multiple choice 2 points
how can you tell if a website is secure for entering personal information?
it starts with \https\ and has a padlock icon in the address bar
it has a lot of advertisements
it starts with \http\
it has a colorful background

Explanation:

• Question 7: Viruses and malware commonly spread through email attachments (which can carry malicious code), downloads (from untrusted sources that might bundle malware), or external devices (like USB drives that can be infected). Antivirus software updates are meant to protect, copying files between programs is a normal operation (not a common spread vector for malware unless the source is malicious), and changing computer settings automatically (without user - initiated action) is more of a symptom of an already - infected system rather than a spread method.
• Question 8: Emails or links from unknown sources are often phishing attempts. Phishing aims to steal information (like passwords, credit card details) or install malware. Making a computer overheat is usually due to hardware issues or resource - intensive legitimate tasks (not typical of unknown emails/links), using too much internet data is more related to large downloads (not the main risk of unknown sources), and slowing down a computer can be a result of many things (but phishing/ malware installation is a more specific and common risk).
• Question 9: A secure website for entering personal information starts with "https" (the "s" stands for secure, using SSL/TLS encryption) and has a padlock icon (indicating a secure connection). A lot of advertisements can be a sign of an un - trustworthy site (but not a security indicator for personal information entry), "http" is not secure (no encryption for data transfer), and a colorful background has nothing to do with website security.
