I tried using msconfig, regseeker, regcleaner, and the startup control panel - and in each of these, when I delete or disable the startup registry entry, something is immediately rewriting it in! So it appears as a second entry, under "run" instead of "run/disabled"
Here's my HijackThis logfile: any suggestions?
