When I start he scan, I get this warning that I am running two Spybots and am only licenced to run it on one computer. This is the only computer on which I have installed the licensed version. I do have the freeware on another computer that I seldom use, but the two computers are not linked. What's happening? Also when I start the scan it takes 2 or 3 hours--is that normal?

Will appreciate help.
