WinXP Pro hangs on startup - virus/malware problem?

Came in to work this morning and noticed my screen was black with white writing - with the F2 and F12 options listed on top. Tried choosing F2, but the computer wouldn't finish booting up. Restarted a few times and finally it booted up correctly, but I'm concerned that this crash is just a precursor...

Maybe during a windows update overnight, something happened?

Anyway, here is my hijackthis log. I would like to get rid of all non-essential items. But keep LogMeIn to start at startup, if possible. I don't know why it looks like my homepage is Yahoo - my homepage is set to Google.

Thanks,
Janet
