Can't remove Trojan on PC. Help.

[Laraa]

Hi,
I have a Trojan on my computer, have tried everything I can find. I've scanned using Malwarebytes Anti-Malware, SUPERAntiSpyware Free Edition, Exterminate it! Free Edition (Deleted found malware with Registry Editor), and Max Spyware Detector.
With the Malwarebytes Anti-Malware Quick Scan, It says there is 1 called Trojan.bho. It comes up on every Quick Scan. When I 'Jump to location' it jumps to HKEY_CLASSES_ROOT\{2C256447-3F0D-4CBB-9D12575BB20CDA0A, but in the log it says HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Ext\Settings\{3F5A62E2-51F2-11D3-A075-CC7364CAE42A}. Plus, when I try to 'Jump to location' and delete it from the Registry Editor, It says there was and error while deleting.
Next, on the Max Spyware Detector Quick Scan. It says there is Trojan.Agent, Downloader.Cmjdown, and Spyware.IEToolbar.
But it won't go away when apparently 'clean'.
Those are the scanners that I have the most concern for.
Logs attached.
Thanks.
