Various Spyware Issues: Dr. Temp, Xlme, ShopNav, etc.

I've got a load of Spyware issues on my computer. The most annoying, Xlime Offer Optimizer, has been terrorizing me for weeks, and I can't get rid of it. The other seems to place a folder called "Dr. Temp" on my desktop repeatedly after I've tried deleting it. Another one is Shopnav, which I've uninstalled, and within days, it returns. There are more, like Ebates Money Maker, which have folders in Ad/Remove Programs that won't let me uninstall, as well as Ebates Web Savings.

Here's my Hijack This! Log, so hopefully someone can help me solve all of my issues. A step by step guide would be easiest for me, because I'm not too computer-literate. Thanks
