The "Security Center" is a minor part of both McAfee suites which provides login security and a single system tray icon to monitor all included programs..

My 2 year subscription to Mcafee Security Center has just run out and now they want to charge me $70 bucks to update it. I was wondering if there is much of an advantage to getting the full 'Security Center' update over the much cheaper 'Virus Scan Plus', is this just a ploy to charge a lot more money or is there good stuff in there? Thank you.
