Zango on Spybot

I've got a strange one here. Today my Spybot picked up 8 Zango registry keys. I've tried to delete them with Spybot but I always get an error message saying:

"Some problems couldn't be fixed; the reason could be that the associated files are still in use (in memory)."

My Ad-Aware got rid of 4 registry keys, but doesn't notice the other 4, nor do Nortan 360, AVG 9, Malwarebytes or VIPERescue. The Spybot report is as follows:

Zango: [SBI $9DB49993] Interface (Registry key, fixing failed)
HKEY_CLASSES_ROOT\Interface\{30B15818-E110-4527-9C05-46ACE5A3460D}
Zango: [SBI $689E03A0] Interface (Registry key, fixing failed)
HKEY_CLASSES_ROOT\Interface\{618AAD04-921F-44C2-BE38-C0818AF69861}
Zango: [SBI $411F0828] Interface (Registry key, fixing failed)
HKEY_CLASSES_ROOT\Interface\{B5D2ED96-62F9-4C2C-956D-E425B1F67337}
Zango: [SBI $9432A0E4] Interface (Registry key, fixing failed)
HKEY_CLASSES_ROOT\Interface\{D3A412E8-1E4B-47D2-9B12-F88291F5AFBB}

And nope, I've got absolutely no sign of Zango in my program files, so a simple program delete is out of the question. Any idea of how to delete this pest and why it only shows up on Spybot?

Hi, Chips.

Try removing in Safe Mode.

Restart your computer in SafeMode by doing the following:

• Restart your computer
• After hearing your computer beep once during startup, but before the Windows icon appears, press F8.
• Instead of Windows loading as normal, a menu should appear
• Select the first option, to run Windows in Safe Mode.

Thanks a lot, that did just the trick!

Excellent! Thanks for letting us know.
