First you have tools to tell if you have a bot but noting to stop one getting established, e.g. an active firewall.
You don't appear to have an active firewall - It should be capable of blocking unauthorised outbound Internet Connections.
Whilst the windows XP firewall is usually good at keeping your ports stealthed (hidden) it provides no outbound protection and you should consider a third party firewall.
Any malware that manages to get past your defences will have free reign to connect to the internet to either download more of the same, pass your personal data (sensitive or otherwise, user names, passwords, keylogger retrieved data, etc.) or open a backdoor to your computer, so outbound protection is essential.
Other than that I don't see anything obvious, but there is a possibility that HJT isn't seeing everything that is running. I have no experience of BotHunter so I don't know if this is an inbound attack detection or an outbound connection attempt and it really doesn't give much information to work with, certainly not for me.
If you haven't already got this software (freeware), download, install, update and run it and report the findings (it should product a log file).
Don't worry about reported tracking cookies they are a minor issue and not one of security, allow SAS to deal with them though. - See
