I recently downloaded and installed the new 2.12.2 version of Nod32. I had to fill in the User ID and password before I downloaded the file--which is the normal process. Now -and it doesn't happen every time--it is intermittent--when I check on Update now, it asks for my password. After deleting and filling in the User ID and password a few times, it will accept it. Anything I can do to correct this? I know that the User ID and password are case sensitive, that is not the problem.
