Problem:
I have installed Norman Virus Control 5.6/5.7, but after installation nothing happens. I am not able to find the Norman program group, and there is no other indications that the program is installed and running.

Solution:
This is a known issue with some older versions of NVC. More information is available here.

Problem:
Windows Security Center reports that NVC is not up-to-date, even if I update it regulary.

Solution:
There is a known update issue related to older versions of NVC. Please verify that you are running NVC 5.8 or newer. More info here.
