back to this virus, I don't know if my version is different (can it be different?) but I can't find this registry key.  However I did find a registry entry for the .KAK suffix, Can I remove this?  BTW,  it activated the other day and I got round it by <Crtl-alt-del>-ing and telling it to end the task.  It removed the box without shutting windows down.
 
Thanks!
