I ran HijackThis but I'm totally clueless on what to do with the results.
If you want you can Freepmail me the results. It is pretty easy to read once you know what you are looking at. Most of the entries will be items running on your system. If you recognize the application, ie McAfee, then it is an ok entry. Entries that you are looking for are miscellaneous ones for internet homepages or unfamiliar applications.
Like I said, I can look at it if you want.
