Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.263.800.0). This update will not install.
This has been going on for months. Definition Update for Windows Defender Antivirus - KB2267602 (Definition 1.263.800.0) will not install. It keeps trying to do it over and over but it never moves forward. It tries to install every single day but it has
never once been successful. I run McAfee Total Protection. I don't need Windows Defender but if I shut it off I get a relentless amount of notifications to turn it on even though I have notifications turned off. I have run the troubleshooter, downloaded a
fix from this site, and done several supposed fixes all for nothing. I have no idea what else I can do.
