Hope someone here can help.
In the last 5 days I have noticed my definitions for window defender KB915597 is at 1.43.801.0 and hasn`t changed at all... Generally i have seen defender updates definitions install without any problems , sometimes several times a week . Both my PC and my wife are Dell desktop machines on Vista Home Premium Edition IE 7 SP 1 for several months and the updates were being installed without any problems until the last one on Sept.26. Nothing in the configuration of Windows Update - Control Panel - Change setting has been adjusted in months.
Has anyone else expierenced this and know what is causing the no updates for defender. One machine has the Symantec anti-virus expired and the other has the McAfee expired but that shouldn`t be the cause since they have been expired for several months and definitions were being installed in the background for months , unless there is some connection now.
thanks for any ideas
