I don’t see anything obvious in your HJT log and I’m not familiar with the runscanner logs.

However, you appear to have a very old JAVA version that could leave you vulnerable, the latest is JRE version 1.6.0_03.

Ensure you have the latest version of JRE (JAVA Runtime Enviroment) because older versions can be vulnerable to malware. First remove All Older Versions From Add/Remove Programs.
Then get the latest update from here http://www.java.com/en/download/index.jsp

You also appear to have some remnants of Symantec.
