Hey guys, in all fairness, reminding you about the ms/free, witch seldom go together.
So, in the maybe 1% win7 usage I do, I do use Security Essentials. It is a little slower and has caught a few problems for me.
OK, sure it's not the best, but in the end, even with witch-ever anti virus one chooses to protect their $ms-os$ it still will likely fail, just because it is ms.
I try to never ever, go online without using PCLOS.
