Which of the following is an effective countermeasure against ransomware attacks?

Question

Options

• ARegularly updating antivirus software
• BAllowing macro execution in all documents
• CDisabling system updates
• DIgnoring phishing awareness training

• A
  92% (22)
• C
  4% (1)
• D
  4% (1)

Explanation

Regularly updating antivirus software (A) is a proven defense against ransomware because modern antivirus tools include signature databases and behavioral detection that recognize and block known ransomware strains before they can encrypt files. Option B is the opposite of safe practice - enabling macros in all documents is a primary ransomware delivery vector, since malicious Office macros are commonly used to drop payloads. Option C removes critical security patches that close the very vulnerabilities ransomware exploits to gain initial access or spread laterally. Option D eliminates your most effective human-layer defense; phishing emails are the #1 ransomware delivery method, so untrained users are easy targets.

Memory tip: Think "UPDATE to PROTECT" - the one action that keeps your defenses current is always the right answer; the distractors all remove a layer of defense rather than adding one.
