I was working this at the same time as mgorman87 - please follow his advice prior to mine.
Perfmon shows many, many issues with the dynamic updates for Microsoft Security Essentials. This is either (IMO) a corruption of the MSSE or a virus infection. Please try a couple of these free scans to rule out the virus': Free Online AntiMalware Scanners (read the details at the link)
If the system comes up clean (and only if it comes up clean) - please uninstall MSSE, then go into Device Manager and remove (uninstall) all devices that start with "MpKsl". Then reboot the system and download/install a fresh copy of MSSE.
FWIW - here's a list of the MSSE corrupted dynamic updated drivers:

I would also uninstall your Acronis software and your BitDefender software - and then install a freshly downloaded copy.
Also, please do the following:
