Trojan.Powelik & Trojan.AdClicker infection

I am experiencing an issue where dllhost*32 has multiple processes, monopolizing my processor (100% usage) and finally causing a crash with blue screen.

Norton 360 failed to find, block, or warn of this malicious threat and I've tried a few of the COTS remedies without success. Any assistance from someone with a greater understanding of how to resolve this would be appreciated.

Thanks in advance for any/ all advice or assistance.

 

Thanks for the assistance. While it was difficult to remove my issue, at least at this time, seems to have be resolved.

Thank you.
