Help, my homepage is stuck.

My homepage is stuck on google.ca (which I did set as my homepage at one time) and won't change regardless what I try. My computer has been slow lately, but functioning relatively normally otherwise. I've run Spybot, Spysweeper, Trojan Hunter, Twister, Spy Ferret, and others, but not much has come up except for cookies. I barely know what I am talking about, so please excuse my ignorance, but I would love to get whatever is keeping my homepage stuck gone! I ran Hijack This and what follows below is my log. Thanks in advance for your help. Sorry if I've left out necessary or obvious info in the explanation above, or failed to properly do something before seeking your help.
