I have installed Norton Antivirus 2002 and 2003 in many computers at my work and i am very dissapointed with its results. Especially with Opaserv, we had many clients infected with this virus, always from e-mails from Outllook or Outllook Express even with the latest update from the internet. I would be gratefull if someone could post some tips for norton antivirus for better results and alternative antivirus. I am mostly interested in Outlook or Outlook Express protection. Tahnks!
