I am using Microsoft Securty Essentials only as the security tool in my system. I had not opted for any other service rather than this. I just don't want to make my system slower by adding softwares and applications in the system. I want to know that does Microsoft Security Essentials can possibly scan incoming and outgoing mails from the various email programs like Microsoft Oulook, outlook or incredicmail. I want to use ClamWin Antivirus in that place how is it.
