In case you were not aware, Microsoft has been working on a new free antivirus program to replace their OneCare security product. This program was codenamed “Morro” but has recently been announced as “Microsoft Security Essentials”. While the public beta was limited to 75,000 people, the installer was quickly mirrored elsewhere, so here is a link to Softpedia’s page for it. I’m using it on a few PCs and I’m thoroughly impressed. Give it a shot, especially if your current A/V subscription is expired.
