My sister, (bless her!!) tells me she is getting an odd programme running when she has accessed the internet. A message is displayed that says "Optimise your privacy & washout your internet tracks clean" Then the screen goes blue and a percentage 'search' is started. This only ever gets to around 60% and the computer hangs. A soft reset will clear this and restart the computer.
The safe money says it some sort of virus but what?
