My Comodo Firewall security log says

"Outbond policy violation (Access Denied, IP =..."

When I look under details, the log says:

"DESCRIPTION: Outbound Policy Violation (Access Denied, ICMP =  PORT 
UNREACHABLE)
PROTOCOL: ICMP Outgoing
SOURCE: 66.19.112.129
DESTINATION: 216.126.128.40
MESSAGE: PORT UNREACHABLE"

WhoIs says that 66.19.112.129 as above is the USLEC Corp., 6801 Morrison 
Blvd., Charlotte, NC 28211 and that 216.127.128.40 is the same place.

Does the above indicate that I've got a virus or something on this thing 
and it is trying to "phone home?" I've scanned this computer with 
everything I can find and nothing has shown up.  Could it be a "rootkit" 
or something like that?

Thanks...
