This problem started yesterday at the same time as another, probably related, issue arose. I'm getting regular updates from my router telling me the following:
TCP Packet - Source:192.168.0.2,2492 Destination:184.108.40.206,80 - [BLOCK]These messages are coming every 15 minutes or so and the 4 digit number after 192.168.0.2 changes each time. That second IP address - 220.127.116.11 - belongs to blogger, I think.
Does anyone have any ideas?
