Start of entries inserted by Spybot - Search & Destroy
That is a good sign - the entries have been added by S&D to point to the local loopback address (127.0.0.1) to prevent your browser ever going to the real sites.
So far so good.
It then lools like AdAware is choking on something that Spybot has done to the hosts file - but since Spybot is benign, I would suspect that AdAware is just flagging a false positive.
It does look like the 12 entries might be like the

entry in your hosts file - I too have 163.com in the hosts file, but not with that character string.
I suggest you edit the file to remove any such corrupted? entries - especially if there are 12.
