Two things - my wireless connection disconnects once my pc goes to sleep and now my Microsoft Security Essentials keeps telling me it is off and I need to turn it on.

I haven't changed anything recently to cause this.  My firewall is on and Windows Defender is off.  I use Microsoft Win 7 and get all the updates (wonder if it is a Windows update problem.) I have used only Microsoft Sec Essentials on this pc so there was never another security loaded on it.

These problems (first the wireless)  started a few months ago and I live with it. The MSE problem just started a week ago.
