55 attemps to open file

I did a full system scan 20 minutes ago. I left my computer during that time and I woke it up when it was asleep. I noticed 55 medium alerts on in the security history (see attached pdf). Something is attempting to open different norton files. Should I scan my computer with malware bytes? I recently did a full restore and it's possible something got into my computer before all the windows 7 updates could install themselves on my computer. It's nice that norton is catching all these but what if there is one it won't catch...what should I do?

 

I mentioned in another post that these occured during my time on youtube and now they happen when my computer goes to sleep.

Hi darnbugs,

 

You can ignore these completely.  Svchost.exe, a Windows process, is trying to access a Norton file.  Norton is blocking it, as it would any other process, and logging the event to assist in any potential future troubleshooting.  It is not an attack and there is no malware involved.  It's simply Norton isolating itself from any outside influence and keeping logs of any events that occur.
