You appear to have a lot of nasties in there. I'm talking worms and stuff, not just a browser hijack.
So probably the best place to start is to go to http://www.trendmicro.com/download/dcs.asp and download sysclean, and this page http://www.trendmicro.com/download/pattern.asp for the latest pattern file.
Unzip the pattern file into the same folder as sysclean, then run sysclean. It will take a while but hopefully will remove some of those worms. Make sure it's in a user area with administrator priviledges.
