Trouble with Search-Daily and AntiVirus popups

It started pretty recently. Yesterday, in fact. I tried to search on Yahoo and Google, but I'd be redirected to "Search-Daily" and their little affiliate sites. Urgh. Then, I keep getting pop ups regarding some "AntiVirus" scan that uploaded it's own little "Caution" wallpaper onto my Desktop. I tried searching for info regarding these two malwares, but it came to find that the ways to correct them differs with each PC. People would come up with things listed on their HijackThis log reports that I never had on mine. I'm just wondering if there's something I can do to get my PC back into the form it was prior to these two nasty little devils jumping aboard? I included my HijackThis log below. Please, I'd appreciate it if somebody could help me, and/or give me some advice on this matter. Thank you!
