Windows defender was started a long time after McAfee was initially installed on a Vista Home OS.
Today, McAfee does not work any longer.
I have stopped defender with msconfig to update McAfee being succesfully with a 20 MB download.
McAfee is controlling now the firewall and all other functions of security.
At this time McAfee wants to boot and I have started the vista home again.
With the new system McAfee Control User Interface (CUI) is empty (in white color).
The only function which offer McAfee to me is scanning.
Does anybody have a hint?
Could you please let us know what is the version of your Internet explorer ?
Did we make any new changes to the computer like a system restore ?
