Well guys, I think I have this one licked 
Think
It hasnt appeared in the last couple hours and usually it manefests its self about every 10 min.
I used the hijack analysis tool to identify the high risk processes/files. I then uses hijack to delete them all from safe mode with restore turned off.
So far, Ive been up and running for a while with no problems.
My fingers are crossed:)
Thanks again for all your help. It was very much appreciated!
Take care everyone and thanks for your replies.
