Recently, for about a few weeks now when I go online with my Mozilla browser a window pops up claiming to be from Microsoft. In the upper corner it says Microsoft Internet Security. Then warns that my browser is in high risk for infection unless I give permission to install Online Protection Tool by Microsoft Windows. Has anyone seen this before? Is this legitimate software from Windows? I Help! Been to other forums and no one is helping. I saved the download and it is from this site http://tresstklos.com .this security software is very legit looking as windows software but I just don't know and wonder if anyone else has seen this, no response from windows. please answer me if you can, greatly appreciated
