I'm calling here for help to get rid of a nasty key from a trojan infection.
My laptop was infected with a couple of viruses, Trojan.BHO being one.
I ran MBAM to remove it and that worked. Only a key entry in the windows registry remains. When I want to remove it manually I get an error message that the key is invalid. Last scans show no signs of an active virus, but the key still remains. I tried to assign all rights to this key and to delete it manually, but I simply can't.
I created a log with dds, which is included here.

======== end of MBAM LOG =======
It says the key will be deleted on reboot, but as I said, that doesn't happen and manual deletion is not possible.
I've searched on many places but I can't find out what I could do next. Attachment of this post includes the ATTACH report from DDS. Advice on how to proceed is very welcome.
