Hello TwinHeadedEagle I hope support for this topic is still supported, as I am having the exact same problem.
Over the past few days the only thing that has worked for me is to disable the processes, eventually the DLLHost.exe COM SURROGATE come back and will grow to around 40,000k-500,000k (Not including the few stragglers at about 1,000k-20,000k).
I use MacAfee, and Malwarebytes Anti-malware software, and neither program gives me any warnings of infection. Updates are current, and I always try to keep a clean system provided by the tools from MacAfee. I also defrag my HDD regularly.
My Operating System is Windows 7 64 bit
I'd be happy to provide any info, please help!
