I've been suffering, like many others, with the slow shutdowns and logoffs. As an experiment I tried turning things off, and I found that with AV off shutdowns and logoffs are fast.
As a temporary measure I've left ZA AV off and installed the free AVG. No problems so far running with this combination. I'll post again if I notice any problems.
As soon as a fix is available I'll uninstall AVG and upgrade to the latest ZAISS.
