Other than those annoying, but not realy symptomatic, redirects your log seems to be clean. Is there some problem occuring?

Here is something for you.

Get the latest version of hjackthis from http://www.hijackthis.de/downloads/hijackthis_199.zip

Then run it and save the log file

Then go to this page and upload your log file. It will analyze your log for you. Then if there are some entries that show up as unknown, you can ask questions about them (search for yourself first). The analyzer does a pretty good job though.
