For several years I use Norton Internet Security with satisfaction but now I feel I make a big leap in the past, when its use became very slow computer. With this update, 2013, using Vault freezes Internet Explorer 9! It takes several seconds before the vault opens, and then again several seconds for the login and password appear! And the same phenomenon appears on all three computers on which I installed this update, including a downloaded online for a netbook. Distressing!
