Free Service description - PC-Cillin  HouseCall
Trendsetter HouseCall from Trend Micro is a no-brainer to use. Connect to Trend Micro's Web site using Internet Explorer, and the ActiveX-based scanner will download automatically. (HouseCall supports Netscape Navigator too but requires Java resources.) From there you simply choose the drives you want to scan and click on the Scan button.

HouseCall's performance is snappy; it checked for all the latest viruses in a little less than 5 minutes, depending of your hard disk size. It also found and zapped all the viruses on our test system without losing data or damaging files.
