Question 3

What are the two ways antivirus software detects malicious code?

Accepted Answer

Antivirus software works by detecting malicious code that has been previously identified in general. It may work using signature detection, which looks for recognizable patterns in executable code that match known malware. A more advanced version uses more general heuristics that look for even more general patterns in order to catch malware that has deliberately mutated in an attempt to avoid detection.
