I have tried elsewhere and searched google far and wide but alas, I cannot remove this god awful thing.
It resides in my Temp folder in my main user account.
I have 6 instances of it dated today and yesterday, all 8.17kb in size. They are named randomly with numbers for names, E.G. 12345.exe.
AVG detects it and deletes it, but it comes back within a couple of hours or so.
Here is a HJT log:
