Hi, After reading all the mixed reviews about NOD32 v3, I decided to try it out myself and install it on my Windows 2003 Server. At first, everything seemed fine. I can honestly say that I did not notice all the complaints about slowdowns. I actually went a few days without noticing any problems or conflicts. Then, I started noticing that my Windows Backups were failing. The built-in NTBACKUP.EXE that comes with Windows was failing to start. Then I attempted to restart the pc by going to the Start menu on the task bar and selecting SHUTDOWN. That's when I noticed the second problem. SHUTDOWN no longer worked! In fact, it causes the entire windows taskbar to lock up and you can no longer click on the Start button or any system tray applications running including NOD32. After uninstalling NOD32 V3, both the Windows Backup and the WIndows SHUTDOWN option started working again. I hope ESET can fix this... I liked the program otherwise.
