 Nick Mediati of PCWorld noted MSE 's " clear @-@ cut " and " cleanly designed " tabbed user interface . He did , however , find some of the settings to be cryptic and confusing , defaulting to " recommended action " , with the only explanation of what that action is to be found in the help file . He was also initially confused because the user interface failed to mention that Microsoft Security Essentials automatically updates itself , rather than having to be manually updated via the Update tab ; an explanation of this feature was included in the final release .
