While cruising through the TechRepublic forums, I found this question from a member who goes by the alias HeavyDuty: “I’m looking to switch from Command Antivirus to some other AV solution. I have Win9x, NT 4.0, NetWare 4.11, and will soon be addingWin2K Pro and Win2K server. I want real examples of why not to use Product X, or why I should choose Product Z.” Great question, and I’ve decided to promote it to this week’s Microsoft Challenge! I’ll add my specific concerns: It should be foolproofto update and ideally should have a way of detecting new viruses before they can do damage to networked PCs. If you think your antivirus software is the very best (or if you have a cautionary tale to share about an AV program you don’t recommend), add your insights here.
