There is no exact cure because there are now many trojans and other things that cause this. I know this doesn't sound helpful at first but I'd start the scans like you read in prior discussions like

Since there are now over a few hundred causes your best hope is the usual scans you see at bleepingcomputer and the malwarebytes forums find it.

I keep getting multiple instances of COM Surrogate Syswow 64 dllhost.exe 32 eating up CPU, and from the Task manager, no matter how many I kill it from task manager, or how many times I run Hitman Pro and MalwareBytes to get rid of Trojans, pups, rootkits, I still keep getting these, and messages from Norton that outgoing access is being blocked to a shady looking website and IP address. I have seen a few videos on YouTube how to "RegEdit" an entry in CLSID {AB8902B4-09CA-4bb6-B78D-A8F5-9079A885} but this may be risky. Has anybody encountered this problem. I was told it's not a virus, but according to me, anything that makes my computer go crazy is a virus. I run Windows 7 64 bit. I would appreciate any help, this is making me mad, and it's annoying. Thanks.
