Hi Ken Sorry, I don't know the version they are made on as they are competition entries, I would assume it would be a version of PTE6 as they are from two of Britain's top workers. - I have moved them to the virus vault for now and updated AVG (free version) which is now 9.0.733 the Virus db is 271.1.1/2728 - I then inserted the CD I received with one on and it still finds the virus.
