text: There are trojans out there that appear as a Windows update but it isnt. If you want a secured windows update, you should go to http://www.microsoft.com and you should click on Microsoft Update to get the true secured update. There are a lot of spywares out there that can enter your computer and trojans can intercept your windows update and hack into your system to install more spywares into your system. You have to be careful where and how you download. I always go through the microsoft website.
