64-bit Trend Micro Housecall can be used to identify many potential threats to your computer. Unlike many other types of security software, this program is primarily used to identify existing problems through system scans and file configuration rather than to protect your computer from incoming threats. That said, once it finds problems, such as spyware, Trojans, or viruses, it can be used to fix the problems and get your computer running faster in doing so.
The program runs independently of your browser, and the download file is just 1.8MB. It automatically scans for updates to existing scan components, so it stays up to date with the latest threats. You can keep a local copy of the launcher and open HouseCall with it whenever you want to run it.
