Hi. I just found your other log posted at ComputerCops.They get very bogged down with logs there & can take a little while to get to you, but it is well worth the wait.
You have a couple of things there that need fixing, but can you also let us know the problems you are experiencing please.
Close all (browser) windows & rescan with hijackthis. When the scan is finished place a check in the box to the left of the following entries & click 'fix checked' :
