Update Components

Virus pattern file: Trend Micro antivirus scan software uses a detection method called pattern matching. Files on a computer are examined and compared to the virus pattern file that contains the "electronic fingerprint" of thousands of known computer viruses. If a file on your computer matches one in the pattern file, the antivirus scan software detects it as being infected.

Spyware pattern file: The spyware pattern identifies spyware/grayware in files, programs and modules in memory, Windows registry and URL shortcuts.

Scan engine (for 32-bit and 64-bit Windows and NetWare platform): The scan engine is the software component that performs the actual virus detect operations.

Virus Cleanup Engine (for 32-bit and 64-bit Windows): the Engine scans for and removes Trojans and Trojan processes. It supports 32-bit and 64-bit platforms.

Virus Cleanup Template: The Virus Cleanup Template is used by the Virus Cleanup Engine to identify Trojan files and processes so the VCE can eliminate them.

Anti-Rootkit Driver (for 32-bit Windows only): Anti-rootkit Driver is a kernel mode driver used by the Damage Cleanup Engine that provides functionality to bypass any potential redirection by rootkits.
