I've got a Sony Vaio laptop. Pretty standard running Vista.
The AV i was using was avast, i have been using it for 3 years now. I reinstalled Windows on the laptop the other day to clear out everything on it and added Avast with no problems. 3 days later and all of a sudden this happens? I havent downloaded anything else before then and only used it for ebay. It has just happened out of the blue this morning.
