About Trend Micro IntelliScan™ Parent topic

Most antivirus solutions offer you two options for determining which files to scan for potential threats. PortalProtect will either scan all files—the safest approach—or true file types and those files with certain file extensions. It is important to note however, that there is an increasing number of attempts to disguise files by changing the extension, which renders the latter option less effective.
IntelliScan is a Trend Micro technology that identifies a file’s true file type, regardless of the file extension name. IntelliScan uses a method that can identify which files to scan and is more efficient than the Scan All files option.
Note
Note
IntelliScan examines the header of every file, but based on certain indicators, selects only files that it determines are susceptible for security risk scanning.
Because IntelliScan scans only files that are vulnerable to infection it provides the following benefits:
  • Performance optimization. IntelliScan uses fewer system resources than the Scan All option.
  • Shorter scanning period. The scan time is shorter than when you Scan All files.
