Exam 312-50v12 topic 1 question 313 discussion

A. Tunneling virus Attempts to intercept or bypass antivirus detection by operating below security software (e.g., by hooking into low-level OS functions). B. Cavity virus Hides itself by overwriting unused space within legitimate files. C. Encryption virus Type of self-replicating malware that encrypts its own code to avoid detection. Each time it replicates, it may use a different encryption key, making every copy look different — a technique that helps it evade signature-based antivirus detection. D. Stealth virus Hides its presence by intercepting system requests and returning false information. While stealthy, it doesn’t necessarily encrypt or mutate its code like an encryption virus does.
