Have you tried or heard of Trend Micro?
They have a free online scan that I have used a few times.

click on free scan, it is very through.
Thanks, Rus.
I downloaded this. I scanned this morning and am now scanning again. I'm not sure that it finished this morning. It seemed as tho it died. I may have lost internet connection while it was scanning.
Hope I find something.
