Virus problem redirecting my firefox and slows my net connection please help.?

Whenever I do a search on my firefox it will sometimes redirect me to different websites like shopping websites or ones that AVG flags and closes. I had run all of my anti virus programs and nothing is picking it up. * Hitman pro 3.5, AVG, Spybot S&D and Maleware bytes. I also ran a Hijack This and saved its log to paste bellow.
