Auto-Protect stopped working?

So this afternoon when I got home, I went to turn my computer on (after it had done windows updates the previous night when shutting down) and it was playing up strangely. After a couple errors telling me it can't start my computer for whatever reason, I restarted once more and I was able to sign in as per usual.

Upon signing into my computer, things were acting all slow and not normal, so I decided to open norton to run a scan. When I opened norton I saw a big red "at risk" sign so I went to run a scan but it failed to run for some reason. After that it told me that my PC is not protected, so I fixed 3/4 with the repair but the Auto-Protect did no repair itself.

Sonar protection        Fixed

Antispyware               Fixed,

Auto Protect              Not Fixed

Email Protection        Fixed

 

Currently this is what it looks like: http://gyazo.com/4c9f6129838ee2e0d2243f39267d0839.

After trying a couple more times I still get the error that it cannot be repaired: http://gyazo.com/0a5be9f0f20772a79efcf8d7b6398b15

If anyone knows a solution to this it would greatly be appreciated. I am still not sure how safe my computer currently is even after running a full system scan due to how it has been playing up today.
