Does anyone know what this ALSysIO service is and/or does? Googling it reveals surprisingly little useful information.

I figured this out... for some reason this is part of Coretemp and it runs whenever you load the app. Why is that not documented anywhere?!

Coretemp doesn't install any services or extra erroneous files afaik as it's just a standalone program I think. I'd do a few spyware scans and delete your firewall settings and start over. Or post a hijackthis log to one of those other security related forums.

Ran ad aware, sbybot, and a squared. Firewall settings look good. I am totally sure it's a coretemp thing.

It's CoreTemp. Stop CoreTemp and check your event viewer. Then restart CoreTemp. Viola... new entry about ALSysIO starting up a.k.a. core temp.
