Some additional info., my wife tells me everything was working o.k. last night but when she shut the system down she received a message on screen saying one update was being installed before the machine shut down. Because of this she left it to shut down automatically after the installation. Unfortunately she did not check what was being installed. We use Kaspersky Internet Security 2013 so there should not have been anything hidden within the update program but I wondered if this may have been the start of the problem and if anyone else has had this happen after installing this update?
