At the LinuxWorld Expo in San Francisco earlier this week, a live test of antivirus products was conducted on the last night.

This time, I want to talk about one of my suggestions - whitelisting. It's a technology that's been around for a while now, but it's something that antivirus companies probably don't want you to know too much about.

When Microsoft bought Sybari earlier this year, you figured this was where they were headed. I certainly didn’t expect them to give away enterprise antivrus solutions (even if the argument could be made they maybe they should give away antivirus software to protect their operating systems). Today, Microsoft finished its acquisition of Sybari and basically announced that it will be selling Sybari’s Antigen antivirus products. Antigen is my favorite antivirus solution for Exchange. It always protected me well when I was running Exchange in my last job. I hope Microsoft keeps making the product better because it’s a nice piece of software.

Microsoft intends to create an antivirus service in the near future, but has not finalized its plans, a company executive said Tuesday.
