All the Best,
There was/is no Help button anywhere in the Interface?
Manuals used to be published but now no longer are, sorry.
Technical Support is free of charge by phone or online chat:
This is why I recommended (Clicking) on Support with-in the Link.
Although the (Url) issue (No Cookies) will not allow me to properly insert.
I just finished a worthless chat session with Mcafee support in which they failed to acknowledge any responsibility for this software despite their copyright all over it. I even provide the serial number provided me when I dowloaded it but they claimed to have no record and tried to throw the blame on AT&T who offered it as part of their internet package. I will try following up with AT&T but hold little hope for support there and I really believe there is absolutely no documentation available for this software which is ridiculous for something that takes direct control of system routines. So I will be uninstalling it and would not recommend it to anyone in the future.
Unfortunately the software provided by AT & T and other ISP's and some computer manufacturer's is controlled by them and often not quite the same as that provided directly by Intel/McAfee.
If there is nothing in the help section of the user interface, all you can really refer to are the FAQ's here: Consumer Support
However, I will inquire internally if there is a manual somewhere in the system.
