Did my computer attack itself?

I opened a page to a website and Norton pops up saying a recent attack was blocked. Im not worried because norton is just doing its job but in the history logs it reads A intrusion attempt by Nate-PC was blocked, thats me. There is then an ip address 192.168 ect

 

The attacker url is google.analytics.tnnnssaxdwr.info/nte........

 

The destination address is google.analytics.tnnnssaxdwr.info (ip address)

 

It also says network traffic from Nate-pcmatches the signature of a known attack!!!

 

Can someone help me?

 

 

PS- risk name is HTTP Neospliot activity 2

 

WHY is the attack coming from MY pc???
