What's new this time? There are no major changes, this release is more about gentle evolution of the product. But for the most part, once you've spent a minute or two browsing the Settings dialog you'll probably be able to leave MSE alone, perhaps even forget it's there: this isn't the type of program to get in your way. So you can, say, limit the program's CPU usage during a scan to reduce its impact on your PC. Microsoft Security Essentials does have a few useful configuration options, too. But you can also run scans on demand, or automatically (via a scheduler), to detect any malware which may have penetrated your defences. Strong real-time protection looks out for and removes threats before they can cause any harm. The core functionality works much like any other antivirus package. Microsoft Security Essentials 4 is the latest release of Microsoft's lightweight, straightforward antivirus tool.
