Has anyone had any problems in the last month or so updating Defender definitions on their Win 7 drives? I keep getting errors on 2 different drives, also a new Win 7 install. Has MS maybe dumped Defender so it can't be updated anymore? The normal Windows updates are working fine, it's just Defender. Also must note I have downloaded the manual definition update file and still no love. I have an Ultimate and an Enterprise version that are having these issues.
