It's quite unlikely that the doctor forgot to do his job. The doctor is very particular. Maybe the spyware has more copies which replaced. I remember having a virus similar to your spyware. Try and search for more files which resemble the spyware file.

Or just open your processes tab in Windows Task Manager. If your a regualr process viewer, you might as well know the processes that usually run. If you spot a process with an unusual name (for eg - loveslow.exe), note it's name, search for it and delete it. Also goto run, type msconfig. In the startup tab, usually you should have your antivirus process and a few more usual processes. If over there you notice a program which you haven't installed, or you don't want to be loaded at startup, remove the check from it, and press OK.
