I really like NOD32 antivirus  but I'm facing issue that I don't seem to be able fix it. I have several internal HDDs that are turned off after 10 min. and they stay that way until I need it. My OS its on SSD and here is the issue...when HDDs are in sleep mode they will stay that way but as soon I open NOD32 either via tray icon or main UI all of the drives are waking up, they will go to sleep after giving time even with UI been open, but as soon I close main UI and reopen it wakes HDDs again.
