Judging from other programs, bye bye other anti-viruses. Microsoft Essentials is light, good and free. It’s a matter of time to be the top anti-virus.

Do you think the same will be better than its previous versions as the same is light weight and thus question arises that will it be able to keep itself updated against the ever growing list of viruses and trojans.
