Warning of possible "Slow Shut Down Bug"

I for several years using the Internal Security products from Symantec and has always been very satisfied. After updating to the 2015er Version (22.xx ...) much to me that my computer suddenly reboot or shutdown will take several minutes despite SSD! I've been using Windows 8.1 x64.

After a few minutes research then my suspicion was confirmed that it is up to Norton Internet Security. The bug is apparently known for some time was not as yet fixed however.

Although Norton Internet Security lt. C't current test is very safe, I can not use the product, unfortunately. After clean uninstallation of restarting work again in a few seconds. I am now switched to a competitor of a Russian provider and the system is now running again.

The problem seems well not to insist on all systems but who has no desire to "Lotto" should grab the same to a competitor!
