I installed Windows 7 which came with Norton Security, a message just popped up saying that the free trial is about to expire and they want to charge me $30 a year for it (or 2 years for $75, which doesn't make sense to me because usually when you order something for more than one year you get a discount, the 2 year should be $50). Should I renew it? I know Norton got a bad rap about 7 years ago. Is there a better alternative? What are you guys using for your internet security for your home computers?
