Why do I get this message of the defender of the widow? -error: 0x800705b4

When I go to windows defender, he says that it does not protect me because it is not lit, but whenever I click to turn it on it gives me this erroe message. Anyone know what this means or what I can do about it?

Perhaps it is because you have the following installed antivirus (AV):
Norton
McAfee
AVG
Microsoft Security Essentials.

The AVs have their own advocates. Having 2 defenders on the same machine will create conflict. Thus, they will stop Windows Defender.
If you have one of those installed, you're OK. You have no problem.

If the above does not apply to start you, here's a way to re - Windows Defender;
Start button > in the search box, type Services > press the Enter key > scroll to find Windows Defender, click on it >...
topic status , it must be said... Has begun
under Startup Type, it must be said... Automatic
If it does not say that, right click on Windows Defender > click Properties > in the new window, make the necessary changes, as above > click OK when the fact of the advantages of others looking for answers, please mark as answer suggestion if it solves your problem.
