1) after norton security has been installed on a pc does it automatically protect all browsers pre-installed and also browsers post-installed? i installed browser CHROME and when i open this browser i can see the norton yellow icon in left/righthand upper corner. as far as i can remember i had to mark off about 5 different protection items when installing CHROME. however, when i installed browser OPERA i had problems and something went wrong. i removed OPERA and reinstalled but the same problem remains. .so when i open OPERA the norton icon is not visible. WHAT WRONG HAS BEEN DONE? HOW IS IT CORRECTED?
