I have been using beta and beta 1a, for a while now, NO errors! I must say I love NOD32, and always have. I am using Vista Ultimate and am happy with the progress of this application, Vista just needed a good firewall. And I had been saying to my co-workers "Man it is too bad ESET doesn't make a firewall" and low and behold! Awesome, Just Awesome!!! Anyhow, on to the ONE thing I have noticed. I see in taskbar properties, Customize Notifications, that the Title of the app is missing. That is all I have to report so far, NO ERRORS! Image of what I mean http://i12.tinypic.com/6af1tow.jpg Will definitely look forward to purchasing this product!
