I experienced this issue myself. In my environment it only seemed to affect 32-bit Windows 2003 and Windows 7. I saw problems with services on desktops/laptops and servers not starting during boot. It was especially problematic on laptop where the WLAN service would not start so the user could not use Wi-Fi. I also experienced problems with services on Citrix XenApp servers not starting after a reboot (I reboot them every night).
Here's the contents of the posting:
"Some users of Microsoft antimalware products have reported a performance issue with signature definition versions starting with 1.141.2400.0 (12/21/2012 1920 UTC).
The current definition files, since 1.141.2639.0 (12/27/2012 0625 UTC), resolve this issue. If you have a signature set in the affected range, please update to the current definition files."
I'm interested in knowing if anyone else was impacted by this.
Monday, December 31, 2012 2:39 PMYes, we encountered some strange issues which we finally attributed toForefront definitions.In our case, people could not log on for up to 45 minutes in variousconfigurations where they could not get past the GINA or were stuck atapplying personal settings.We determined it was for front by finally getting the computers tostart in safe mode and disabling the Microsoft Antimalware Service andrebooting. After that, it behaved as normal, but if it was re-enabledand rebooted it went back to being a problem.So finally after forcing a definition update the issue came clear.In our case, I think all affected computers also had a CiscoAnyConnect VPN software installed, although the symptoms appeared evenwithout a VPN connection and in some cases even without a networkconnection.EdwB wrote:>Some users of Microsoft antimalware products have reported a performance issue with signature definition versions starting wi

I agree it was strange not to see lots of activity as it sure caused us some grief and definitely consumed lots of time. :-)
