please check out my log

background......
I am having starting issues. It takes about 2-5 minutes sometimes after I press the power button on my machine to actually go to my log on screen. It goes through the normal start up at the beginning, checking for drives and memory and all, but then its just a blank screen for a while till the windows logo appears and then my log on(password screen) screen I have had this issue for a while now. I also currently get when my desktop opens, a DLL error about an "adode" file missing in
"c:\documents and settings\Administrator\Local Settings\Application Data\Adobe"

here is my log from combofix, which I ran after scanning my computer with "Vipre" and "CCleaner"
