You got the peper trojan. Once you run the following tool you may want to post the entire log. You have other stuff that I can see that needs to be removed.
Clear the contents of the following folder in safe mode;
C:\docume~1\owner\locals~1\
temp
In order to view these files you may have to select 'show hidden files/folders.' Instructions on how to
here.
Uninstal *Mywebsearch* from add remove programs. Also uninstall 'Window Search', 'Window Searching', 'Lop.com', 'LOP SEARCH', 'Browser Enhancer', or 'Ultimate Browser Enhancer' if listed. You may be given a code to insert, do so and reboot when done. If not listed there, run this uninstaller:
http://lop.com/new_uninstall.exe
Download the PeperFix.exe tool from here:
http://downloads.subratam.org/PeperFix.exe
Click on the PeperFix.exe to launch it.
Click the Find and Fix button.
It will scan the %Systemroot% folder and locate all the peper files. You will be prompted to reboot. Reboot and it will delete the peper files.
Ensure that you are online before starting the fix. Make sure to run the fix twice.
