The wireless network it's been is password-protected and all networks it's on have been firewalled. I ran a full scan via AdAware, Spybot, and Norton2004 (after getting the most recent update for all of them) on Friday, caught a few things but nothing horribly evil. But virii/spyware is tricksy and I can't absolutely rule it out. I got an external case for the 180-gig HD that's in my desktop PC and haven't taken the OS off it yet, so I can take out the laptop's hard drive, plug in the 180-gig, and it should just boot and run (I'm fairly certain it can boot from the USB port, since it tries to boot from just about anything plugged into it). We'll see how that goes when I get home from work.
