MSE: Introducing Microsoft Security Essentials

Hi – I would like to share some information about Microsoft Security Essential (MSE) and
more information about how viruses and antivirus programs work.

Introducing MSE
Microsoft Security Essential (MSE) is Microsofts latest antivirus (and antimalware) program. MSE works like many other antivirus programs, however, what so special with MSE is that it doesn’t require much system resources (e.g. CPU, RAM and the latest Windows® OS).
MSE is also very user friendly, it has a very nice UI.
