I just wasn't sure what to look for
Just type in the name of the file in Google and you will get a lot of results. But be carefull from what sites you accept the information. Some aren't giving you the correct info. Sites like liutilities, iamnotageek and 2-spyware are very trustfull and acurate with the information. But others may not be.
If you find things with HijackThis and want to know about them....... Use my HJT log analyzer, it is not perfect nor does it recognize everything, but everything it is recognizing is personally checked by me. And after releasing (about) 35 versions of it, there where only two things that where recognized wrong. Also have a look at the HJT section at my website. It has (links to) a lot of usefull information.
About the firewall:
It looks like a problem with the firewall itself. There should be no reason why rebooting is resetting the firewall. Perhaps remove it, reboot and reinstall (and setup again ofcourse) may solve the problems.
