This may or may not be a NOD32 problem, but I'm curious to know if anyone else has seen Power Management changes since installing v5. One of our Windows 7 machines went weird around the time v5 was installed. Just ran a power efficiency diagnostic to see if I could discover why the machine stopped sleeping. Got a number of "not entering the suspend state" errors. I think I'll take the machine back to v4 and see if the power management on this machine returns to acting normally.
