Ever since I upgraded to Bitdefender Total Security 2015, every time I restart my PC, i get a message saying that windows automatic update is disabled, and every time I change it, and after a restart, windows automatic update is disabled. I have run multiple full scans with both Bitdefender and Malwarebytes Anti-Malware, and neither of them have turned up any kind of infection, so there's no known malware that keeps disabling it. I had this problem with Windows 8.1 Update 1, and the Windows 10 Technical Preview.
