Traffic has been blocked from this application: (svchost.exe)

I know this has probably been brought up many times, but Ive yet to find anything to help me.

I am using SEP 12.1.1000.157 RU1.

Basically I want to try and find out if I have been infected by a virus or some malware, or if SEP is just going crazy. I have not been able to find logs or anything so I dont have much to post however if they are needed and someone can give me directions on where to find them, I can post them.

I'm running Windwos 7 Home Premium 64 bit.
