The avast! icon is not rotating. The network connection icon may be an artifact of the wireless connection to my DSL gateway? The lights on the gateway blink regularly, like it is verifying the connection. There does not seem to be anything overt using CPU power when this is happening. As I said, running Filemon and Procmon reveal nothing unusual. I am wondering if this might be windows indexing for search? To be honest, I only noticed it a little over a week ago. It may have been happening longer.
