Hi Monique and welcome to TSF! Your log is clean, but I will share a few recommendations:
SpyKiller is a barebones spyware removal tool that provides little more than the most basic detection functionality. It does not provide detailed scan results and you're unable to conclusively determine its effectiveness. However, SpyKiller may be finding “false positives” in an effort to goad users into purchasing the product.
To help prevent future spyware installations/infections, please read the
Anti-Spyware Section and use the tools provided.
I would also recommend removing WildTangent. This is an online gaming package that is installed by a number of third party applications and even OEMs, ISPs and AIM. The games aspect of this is really rather cool. The being installed without you asking for it isn't cool at all. They collect information about you and your usage.
Make sure to update Windows and Internet Explorer at
