Antivirus keeps shutting down

Microsoft Security Essentials keeps on shutting down for some reason. I have looked online, and have already done everything, but it keeps on telling me that windows is not protected, despite updating and scanning everyday. i dont get why. do i have some malware? I have used malwarebytes, hijackthis, and MSE itself, and nothing has come up. I have even installed AVG for a short time to try to find the problem, but nothing came up either

also, I have found it impossible to turn on windows defender. would that be why MSE is acting up?

hi there before we get to the complicated stuff have you tried un-installing and re-installing the security software? and its always best to not have more than one security software installed.

uh-oh. i used the wrong words in my original post. it originally made MSE tell me that it hasnt scanned for a while (orange banner and icon). i changed windows defender to auto, and when i restarted, MSE really shutdown (red banner and icon). and windows defender went back to manual, despite me having clicked both apply and ok

MSE includes Windows Defender, so you can disable that in "services".

Windows Defender and Microsoft Security Essentials

Applies To: Microsoft Security Essentials | Getting Started and Upgrading

Q: How is this different from Windows Defender?
A: Windows Defender detects and removes known spyware only. It is not designed to protect against the full breadth of malicious software, and specifically does not prevent viruses, worms, Trojans, and other malicious software from infecting your machine. The new no-cost solution will be a comprehensive anti-malware solution.

Q: Is Microsoft Security Essentials designed to replace Windows Defender?
A: No but if you are running Microsoft Security Essentials, you do not need to run Windows Defender. Microsoft Security Essentials is designed to disable Windows Defender in order to manage the PC’s real-time protection, including anti-virus, rootkits, Trojans and spyware.

Q: Does installing Microsoft Security Essentials disable Windows Defender
A: Microsoft Security Essentials should disable Windows Defender on Vista and Windows 7 and uninstall it from XP. In some cases, this does not happen automatically.
Q: Do I need to manually disable or uninstall Windows Defender if I am using Microsoft Security Essentials?
A: If Microsoft Security Essentials did not automatically disable Windows Defender on Vista or Windows 7, you should disable it to prevent conflicts. Windows Defender cannot be uninstalled from Vista or Windows 7.

If Microsoft Security Essentials did not automatically uninstall Windows Defender on XP, you should manually uninstall Windows Defender via Control Panel/Add or Remove Programs.

Q: What happens if I do not disable or uninstall Windows Defender if I am using Microsoft Security Essentials?
A: If Microsoft Security Essentials and Windows Defender are both running, your system may experience performance degradation and other problems caused by the conflict of two services providing real time protection simultaneously.
