Sudden very heavy HD usage - malware? How do I identify the cause next time?

Yesterday evening, the HD on my laptop suddenly started going mad. I don't know what was causing it, but no other application could run.

I re-booted in safe-mode, and ran anti-malware scans (all just updated) - Microsoft Security Essentials, AntiMalwareBytes and SuperAntiSpyware. Nothing showed up, but the HD activity stopped. I also downloaded and ran Autoruns, but I couldn't see anything that was obviously alien.

Is there a reasonable explanation for this (perhaps index rebuilding, or something)? If not, is there a way I can tell next time what's causing this burst of activity, so I can deal with it?

Thanks
