Hi,
Try Spysweeper http://www.webroot.com/downloads/
Also make sure all security patchs are installed.

>My daughter caught this trojan and we can't seem to get rid of it. McAfee finds it every 10 seconds, says that it removes and cleans the file, and immediately pops again with the same problem. We tried to scan the computer with McAfee but to no avail. Also, downloaded Ad-Aware PE, ran it, no help. Google search didn't give much help. Interesting that McAfee info about this trojan says "low risk" but to me it seems as annoying as hell.
