Signatures should be checked before scan
Why This Matters
Running antivirus scans with outdated signature definitions leaves endpoints vulnerable to newly identified threats. If signature updates are not verified before each scan, the scanner may miss recently discovered malware, ransomware, or other malicious code. This control ensures scans operate with the latest protection intelligence, reducing the window of exposure between signature release and application.
