I'll play a little without researching the entries - get rid of everything that says
http://srch-us4.hpwis.com/
see if this is a legit program - Program Files\Zero Knowledge\Freedom\FreeBHOR.dll if not get rid of it, all entries to it
and anything your not sure of google it and see if its a legit program..
and you should be doing this in safe mode with sys restore off, so I would take out everthing with this
http://srch-us4.hpwis.com/ reboot and run everything again and post another log and see if your ok - and also dont surf unless you download all the ms patches
