What is IntelliScan?

IntelliScan is a Trend Micro technology that determines which files to scan for malware based on the actual file type, rather than just the file extension. This is done by analyzing the file header, allowing Deep Security to correctly scan files even if their extension has been changed to disguise their true nature.

From the official documentation:

“IntelliScan is a scanning method that identifies the true file type by examining the file header, instead of relying only on the file extension. This ensures that malicious files cannot evade detection simply by renaming extensions.”

Option A is correct and matches the official explanation.

Options B, C, and D are incorrect and describe features not provided by IntelliScan.
