At the moment, my sys tray icon is green, so at least I'm fully protected, but if I right-click and choose "open window", I simply get a "minimised" ESET NOD32 Antivirus in the taskbar...any attempt to open/maximise/etc fails, it just sits there. Had v4.0, upgraded to 4.2, no change. Uninstall, reboot, re-install, no change. I have NOD deployed throughout my estate at work (XP, Vista, Win7), yet this is my home Win7 ... so far more important Anyone else encountered this? Thanks for looking. Zad.
