It's been a whole year since Microsoft released its first truly competent antivirus, and the company is celebrating its anniversary by sharing a number of user statistics and other Microsoft recently opened its arms to small business users. Starting next month, office settings of up to 10 computers will be allowed run MSE free of charge. Also, HP will be shipping MSE preinstalled on its new Envy 14 notebook series (which we're in the middle of reviewing, by the way). The next version of Microsoft Security Essentials is currently in beta and it should arrive sometime early next year.
