You attached it OK, twice
I assume they are the same, I've only opened the last one.
I don't know where you got your copy of HJT but it is out of date, get it here:
FileHippo Download - HiJackThis and post the contents of the HJT log file here. This file is an executable installation file so you won't have to unzip and extract the files it will create its own program folder.
Here is a helpful tutorial - HJT Information
HiJackThis Tutorial.
So it would be best to get the new version and run the log again, now you know how to attach it.
If this entry appears the next time you Run HJT it can be fixed.
O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file)
Other than that I don't see anything obvious, but we can check again when you run the latest version of HJT.
Also you don't appear to be running an active firewall, or it is disabled or it is the XP firewall.
Your firewall should be capable of blocking unauthorised outbound Internet Connections.
Windows XP's firewall is better than no firewall but, it lulls you into a false sense of protection, it doesn't provide outbound protection. 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.
