Most antivirus solutions today offer you two options in determining which files to scan for potential threats. PortalProtect will either scan all files (the safest approach), or only true file types and those files with certain file extensions. However, a trend of disguising files by changing the extension makes the latter option less effective.
IntelliScan™ is a Trend Micro technology that identifies a file’s true file type, regardless of the file name extension. IntelliScan uses a method of identifying which files to scan that is more efficient than the standard Scan All files option.
IntelliScan examines the header of every file, but based on certain indicators, selects only files that it determines are susceptible for virus scanning.
Because IntelliScan scans only files that are vulnerable to infection, using IntelliScan brings you 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.
