Spybot detected a BHO and reg entry of "Virtumonde.Generic", and purportedly removed it. However, on the next restart, it was back.
I've tried both Spybot and SUPERAntiSpyware, which found a few more registry entries, and still the BHO keeps coming back. I've tried all the specialised removal tools, and they don't pick it up, and the values listed in step-by-step removals aren't present. I've even manually deleted all the registry entries that refer to its ID, without any difference. As the log shows, the problem is that the detection doesn't refer to a file which I can delete, but there's something that keeps it coming back.
