I have used Nod32 for the last two years successfully. I renewed the license in November 2002 because it's the best AV I've found. I installed it the other day on top of version 1 and had some minor issues so yesterday I uninstalled it, cleaned the registry, and deleted all the folders. I reinstalled it and it works fine except....I have it set to check every couple of hours for an update. I checked today to see if it had updated and noticed the log showed "update attempt terminated with error (Incorrect username or password)." I copied and pasted (again) my username and password and was able to manually update it. What is up with that? I'm running XP Pro.
