I'm quite disappointed in Nod32. Today I found an antivirus-like program "checks" my system, imitates the Windows security alerts and disables any program I would like to open including task manager. I restarted, managed to kill the process before it appeared on screen. Installed Nod32, made a system check, nothing. Then I restarted again, to confront nod with the virus. Amazingly, the virus disabled nod's realtime protection (protection state said disabled, settings shown it was on). Then I had nod check the folder where this virus was located (/application data) - it had a single exe file. Nod found nothing. So wtf?
