Constant notifications of joining a new network?

Hi everyone. My computer began acting up all of a sudden and I decided to check my event logs. As I was strolling through what my the event viewer has recorded, I found this :

Subject:
Security ID: ANONYMOUS LOGON
Account Name: ANONYMOUS LOGON
Account Domain: XXXXXXXXXXX
Logon ID: XXXXXXXXXX

This event is generated when a logon session is destroyed. It may be positively correlated with a logon event using the Logon ID value. Logon IDs are only unique between reboots on the same computer.

AND

Subject:
Security ID: NULL SID
Account Name: -
Account Domain: -
Logon ID: XXXXXXXXXXXXX

New Logon:
Security ID: ANONYMOUS LOGON
Account Name: ANONYMOUS LOGON
Account Domain: XXXXXXXXXXX

Also, Comodo Firewall has constantly been notifying me that my computer has joined to a new and different network that looked weird. My scvhost.exe is some how connected to that weird ip with over 200 connections to that ip. What shall I do?
