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.

NoteIntelliScan 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.
