1368070 2014-02-19 05:29:00 How do I start the programme? When I click on it I get the message that its switched off and I have no idea how to switch it on. Greg (193)
1368071 2014-02-19 05:53:00 It does that sometimes, (used to do it when I removed MSE in Win7, because it doubled the boot time), why I have no idea. Try rebooting see if that fixes it. Then update windows again. There are updates after 8.1 Speedy Gonzales (78)
1368072 2014-02-19 06:01:00 Are you in Win8? I understand that in 8, if you have an antivirus installed, Defender will not install as it has an antivirus component in it that would clash with your antivirus. Bryan (147)
1368073 2014-02-19 06:04:00 Win 8 comes with windows defender. You can't install security essentials. But you can install anything else Speedy Gonzales (78)
1368074 2014-02-19 06:07:00 Windows 8 or 8.1 will auto disable if another antivirus is installed and you cant turn it on.


Usual reason:
If the other AV is uninstalled and Defender doesn't turn back on after a reboot its generally because the previous AV has left components behind.

What you sometimes have to do is manually turn it on.

W8 /8.1 go to the start tiles. type in Action Center open security and see if teh option to turn it on is there.

1368075 2014-02-19 06:41:00 Thanks guys. I have the stupid trial version of Nortons - was reluctant to uninstall it until I got Defender running first. Guess I'll; do it the other way round. Greg (193)
1368076 2014-02-19 07:13:00 Run "Nortons' removal tool" to get the lot. Bryan (147)
1368077 2014-02-19 18:32:00 How do I start the programme?

Why bother? It's pretty useless too.
Get something decent instead.

1368078 2014-02-19 19:51:00 Sorted - uninstalled Norton and Defender is now active. Greg (193)
1368079 2014-02-19 20:22:00 I am glad I came upon this thread, I have a friend who has McAfee installed on his Windows 8.1 machine. McAfee trial is about to expire and he wanted to be reassured that Windows Defender would automatically kick in.
I told him I don't know for certain, but to remove McAfee, and have a look in the Action Center and see if Defender is switched on.
He tried to remove McAfee through Programs and Features but it would not go! He is pretty much a techphobe, so I guess he is missing a step somewhere. I might have to go there and sort it for him.

I'll try to get him to buy Nod 32, but he is a pensioner and can't afford much.
