From Trend Micro:
Trend Micro HouseCall (64-bit) can quickly identify and fix a wide range of threats including viruses, worms, Trojans, and spyware. It is now faster, more powerful and browser independent. When a user starts Trend Micro HouseCall (64-bit) for the first time, a small executable (1.8MB) is downloaded. This launcher application runs locally and manages the download of local scanning components, such as the scan engine, configuration files, and pattern files. On subsequent scans, the launcher checks for existing scanning components and downloads them only when they are outdated. If you save a local copy of the launcher, you can use it to open HouseCall anytime.
What's new in this version:
Version 8.0 has enhanced detection, cleanup, and scanning.
