Microsoft Security Essentials

The release of Microsoft Security Essentials has changed the landscape of antivirus software. We've finally got a completely free application that protects against viruses, spyware, and other malware—without killing system performance like some of the "suites" tend to do. In my personal experience, it barely slows down the machine and rarely affects my work—and during a deliberate attempt to download some viruses (for testing purposes), it immediately found and blocked them from doing anything.
You don't have to take my word for it, however. Not only did AV-Test.org find that it detects 98% of their enormous malware database, but AV-Comparatives (a widely known anti-malware testing group) found that MSE was one of only three products that did well at both finding and removing malware, including the leftovers. It was also the only free product to grab their "Advanced+" rating—the top honor for an anti-malware solution.
