Administrators AWS Posted April 11, 2013 Administrators Posted April 11, 2013 Today,4/11//13, I downloaded the recommended updates for Microsoft Security Essentials. Is it necessary to also download the optional one the Definition Update for Microsoft Security Essentials - KB2310138? It's listed as optional but I don't really know if it is necessary to download it. I don't know what changes it will have on the other download. So, I'm asking you - do I NEED it? Thank you for your time. *** Email address is removed for privacy ***, Barbara Emerson. View this thread
