Norton AV is always among the top when AV comparison tests are done, yet I see it constantly miss viruses and computer with NAV updated and installed massively infected. Well, my boss just asked me, hey this looks like a virus, I siad it sure did. It was a small 146k attachment named message.zip. I said to save it to your hard drive and scan it without opening it. He did. NAV say all clean. So I extract the zip to find message.zip.cmd. I knew it was a virus, but NAV said it was clean. I decided to send it to virusscan.jotti.org and here are the results: AntiVir Found Worm/Stration.C ArcaVir Found Heur.Win32 Avast Found nothing AVG Antivirus Found I-Worm/Stration BitDefender Found Win32.Worm.Stration.AH@mm ClamAV Found Worm.Stration.EK Dr.Web Found Win32.HLLM.Limar F-Prot Antivirus Found W32/Warezov.CK Fortinet Found nothing Kaspersky Anti-Virus Found Email-Worm.Win32.Warezov.bi NOD32 Found nothing Norman Virus Control Found W32/Stration.OZ UNA Found nothing VirusBuster Found Trojan.Opnis.Gen!Pac2 VBA32 Found Email-Worm.Win32.Warezov.bi NOD32, AVAST!, UNA, Fortinet and Norton [on my bosses PC] missed it, everyone else found it, including AVG, which seems to always get blasted in those comparison tests. The morale of the story is, don't use Norton AV. Yet the powers that be here, still think that you need Norton and not someone else, I just don't understand it. Although it probably explains why Microsoft is so popular, they might have a terrible track record, but you still recognize the name.
