What is the main difference between static analysis and dynamic analysis in antivirus programs?
What is the main difference between static analysis and dynamic analysis in antivirus programs?
- Static analysis compares potentially dangerous code to rules and patterns while dynamic analysis tests for malicious activity. (correct)
- Static analysis matches known malicious code while dynamic analysis looks for virus signatures.
- Static analysis tests for malicious activity while dynamic analysis compares code to a set of patterns.
- Static analysis updates antivirus definitions regularly while dynamic analysis uses fast pattern matching techniques.
How do antivirus programs detect viruses through signature-based detection?
How do antivirus programs detect viruses through signature-based detection?
- By trying to replace every file on the hard drive every 30 seconds.
- By looking for digital signatures embedded in the virus code.
- By searching for large sections of the virus code within files.
- By comparing the analyzed object with a database of signatures. (correct)
