Hi AegisRose,
Have you installed CCleaner on this machine? I think that by default it installs Yahoo Toolbar along with itself so that may be where it came from.
I can't see any malware in your log, that doesn't guarantee your machine is clean but it's a good sign. If you have no other symptoms or concerns then from what you have said I would expect the machine is very likely to be clean. If however you are concerned or have other symptoms to report then we can have a closer look.
Please let me know how you would like to proceed.
