I can't start windows security center since installing Nod32, I keep getting the error message. is there a known fix? "The Security Center service failed to start due to the following error: The service did not respond to the start or control request in a timely fashion" I have search for about 2 weeks for a solution until finally contacting Hp support group and this is a part of the chat: Annice A : Ronnell, the Nod32 antivirus will block the windows security center. Annice A : I recommend that you remove Nod32 and check whether the issue is resolved. Annice A : You are Welcome. Annice A : This is a known issue with Windows Vista and some anti-virus applications.
