hello sorry I don't think its any thing to do with mirc, I have a better understanding of what is actually going on.. and Yes definitely infected with something causing my specific problems.. obviously I am trying to test drive windows 8.1 Pro for personal and business purposes but the version i have picked up has been brutalized by 1 or more trojan/bit coin miner...
I will share with you my notes thus far

-----------------------------------------
After clean install noticed high CPU utilization levels causing turbo mode to be permanently on
after examining processes and command lines in task manager
We find attempts to hides by switching off intensive cpu code when Task Manager is active.
We find cvtres.exe executing:
*stratum+tcp://stratum3.dogehouse.org:8080*dmk001.5*x*
Located in HKLM/ Software/Mircrosoft/Systernals
Some hours later machine starts to exhibit high cpu utilization again
after rexamnine of task manager Wscript seen running 27218346293184.vbs
Located in c:\ProgramData\{$1284-9213-2940-1289$}
File: 27218346293184
File: BMDStreamingServer.exe
Termination of .vbs script does not reduce processor utilization.
Termination of BMDStreamingServer.exe alleviated high load.
Removed Autorun entrys for BMDStreamingServer and deleted {$1284-9213-2940-1289$} from C:\programData\
All Clear for now!
