I hope someone out there can help me. After installing Norton Antivirus 2011 my computer refuses to remain in sleep mode. What gives with this situation? When I put my PC to sleep, just a few short seconds later my PC wakes again! I have clicked on eveything in the Norton Window and have found nothing that pertains to the sleep mode. I went into my power options and everything is the same as it was before I downloaded Norton Antivirus. So someone help me please. Thanks a head of time.
