Thank you Rat Rage Kid for posting the note and the instructions on how to delete the files.

I don't know how Onflow got on my PC, but I didn't ask for it and didn't want it. I found an uninstall program that seemed to claim to remove the code but it didn't do anything except issue some warning that I needed to close any browsers and Windows Explorer.

If I didn't have a firewall in place I wonder whether I would have known that someone had put this crap on MY machine.

Thanks again.
